I already have an in-house email-sending tool paired with a verification platform. Before we scale further, I want a fresh set of expert eyes to confirm that everything is configured exactly as it should be and to tighten up any loose ends you spot. Here is what I expect: • A thorough review of the current sending application—server settings, DKIM/SPF/DMARC alignment, bounce and complaint handling, throttling rules, and any other factors that influence inbox placement. • Confirmation that the verification platform is running flawlessly and catching invalid or risky addresses without slowing campaigns down. • Clear, actionable fixes applied immediately where issues are found, plus concise notes explaining what was changed so I can trace the logic later. You are f...

I need a WordPress pro to bring every plugin on fully up to date, make sure nothing breaks in the process, and then re-organise all category listings so they appear in clean alphabetical order across the entire site. Plugin side: I’m not certain whether new extensions are required, so I’d like your advice on anything that could improve security, speed, or ease of maintenance while you’re inside the dashboard. We’ll take a backup first, run updates in a staging environment, then push to live only after everything checks out. If a premium licence is needed for a vital add-on, flag it before purchase. Category ordering: every front-end and back-end view that exposes the site’s categories needs to reflect the same alphabetical logic. I haven’t decid...

This project covers the end-to-end compliance layer for our web-based RegTech platform. The work spans user and business verification through to real-time transaction oversight, and every module must interoperate cleanly so auditors can follow a single, transparent trail. Scope The build must include: • KYC – onboarding flow, ID document capture, liveness checks, sanctions & PEP screening • KYB – business registry look-ups, UBO discovery, document management • AML Screening with ongoing monitoring – nightly batch re-screening plus instant alerts on match escalation • Transaction monitoring – rule engine able to flag velocity, amount, pattern and geo anomalies in real time • Risk logic – configurable risk scoring that b...

I’m ready to collaborate with a stateside programmer who speaks and writes English effortlessly and located in only US. The work revolves around building and refining products that lean heavily on Python, JavaScript, Java, and broader Artificial Intelligence concepts. Day to day you’ll be hands-on with Machine Learning pipelines, Natural Language Processing services, Computer Vision modules, and Retrieval-Augmented Generation (RAG) techniques, transforming ideas or research into clean, production-ready code. We will outline milestones together, but every sprint will share the same expectations: write maintainable code, test it thoroughly, push through Git, and discuss design decisions in real time during U.S. business hours. If you can point to recent projects that showcase de...

I need a fully automated workflow that reliably “watches” at least 1,000 Instagram ads every single day so I can collect the associated revenue. The script, bot, or cloud-based setup you deliver must exclusively target Instagram placements and be able to run without manual input once configured. Key expectations • Simulates authentic user behaviour—randomised watch times, scrolling, pauses, and account switching—to minimise the risk of detection. • Handles video, carousel, and story placements seamlessly; the system should not break when Instagram rotates formats. • Supports rotating residential proxies or another anti-fingerprinting approach so the view source appears organic. • Provides clear daily metrics (views achieved, ads skippe...

Google has warned me that my Play Console account will be closed for inactivity. I did try to trigger some activity on the account, yet the closure notice remains. What matters most right now is pushing an update for the existing app so data, reports, and overall access stay intact. I need someone who can: • Analyse the current state of the Play Console account and the warning notice • Prepare a minimal but compliant APK/AAB build (even a small version-code bump is fine) in Android Studio or a similar tool • Guide me through signing it with my original keystore and uploading it for review • Confirm the submission shows as “active” in the dashboard and that the account warning is lifted Acceptance criteria: 1. An updated release is successfully publis...

I already have an image-based AI model running locally; now I want a full desktop application wrapped around it so end-users can load an image, send it to the model, and immediately see the results. Your task is to build both the user-facing interface and the supporting backend layer that talks to the model. Frontend • Cross-platform desktop GUI with a clean, responsive layout. • Controls for selecting or drag-and-dropping images, triggering inference, and viewing the returned prediction or annotated image. • Space to display status messages (e.g., “processing…”) and basic settings the user might tweak before running the model. Backend • Lightweight service (Python Flask/FastAPI or similar) that wraps the existing model, handles image prepro...

I'm ready to commission a cloud-hosted order management tool that traders can access as a subscription service. The core of the platform must deliver real-time stock price tracking and the ability to fire off trades automatically; I also want the flexibility to toggle between fully automated and semi-automated order flows from the same interface. Order coverage should start with all type order instructions, and I'd like the architecture to be open enough that orders function can be added without a rewrite. Execution will route through leading brokerage APIs, so clean, well-documented connectors and a sandbox mode for testing are essential. Key deliverables • Web-side dashboard that streams live prices and order status with no latency. • Rule engine or scriptin...

I already run my store from an app I put together with Base44’s no-code builder, but the recurring subscription fees are no longer an option. I need that same application rebuilt for Android only and delivered as a standalone APK that I can install directly on my own devices. All current screens and flows—inventory, sales figures, simple customer alerts and the dashboard—must work exactly as they do now. I will share screenshots, credentials and a walkthrough video so you can mirror them pixel for pixel. Please wire the new build to Supabase (or another open-source backend you recommend) so I can self-host data, authentication and push notifications without ongoing costs. I’m still deciding whether to add new features, so structure the code cleanly and leave room f...

We are looking for an experienced Python Freelancer to work on our existing HRMS (Human Resource Management System). The HRMS is already developed and operational, and the freelancer will be responsible for modifying existing functionalities, adding new features, and making system enhancements based on our business and HR requirements.

Key Responsibilities • Modify and enhance existing HRMS functionalities as per business and HR requirements. • Develop and integrate new features and functionalities based on organizational needs. • Customize workflows, for...

I need a web-based ERP module dedicated to subcontractor work order management. The core of the build is a clean interface where I can create a work order, assign it to a subcontractor in just a few clicks, and later pull meaningful reports without having to wade through unnecessary screens. Key functions I must see working end-to-end: • Work order creation and assignment, including status, deadline, and cost fields. • Reporting and analytics that let me filter by date range, subcontractor, and project, then export to PDF or Excel. The system will run entirely in the browser, so please use a responsive front-end framework and any modern back-end stack you’re comfortable supporting. I’m not asking for broader ERP features such as full inventory, CRM, or HR at this ...

I want to turn a single Android phone into a 24-hour ad-viewing machine that can reliably play through roughly 1,000 video ads every day and credit each completed view to my account so the revenue comes straight to me. Your job is to build the full workflow—from launching the ad source, through watching the videos in the foreground or background, to confirming each view and moving on to the next one without manual taps. Key needs • 100 % Android-only solution (no Windows, macOS, or Linux tools in the loop). • Works on a standard, non-rooted smartphone running the latest public Android release. • Handles the entire cycle automatically: open ad, let it run to completion, wait for the “Close” or “Next” prompt, then continue. • Stays u...

I need a Windows-only desktop application that runs entirely offline. The workflow is straightforward: 1. I open the program, browse my local folders, and pick any .mp4 file. 2. Before the scan starts, I set the frame-sampling rate—this could be every frame, every nth frame, or even a custom decimal rate such as 2.5 fps. 3. The app then performs object detection on those chosen frames. I do not mind which framework you use (YOLO, TensorFlow, OpenCV, ONNX, etc.) as long as everything is bundled so the tool works without an internet connection. 4. When the run finishes, the program produces a plain .txt sheet: one line per analysed frame containing the timestamp and the symbols / class names it detected. No other file formats are required. Deliverables • Stand-alone ...

I have a time-series collection of remote sensing data—specifically multi-spectral satellite imagery—and I need an AI model that can reliably pinpoint and quantify changes that occur from one acquisition date to the next. The end goal is an automated workflow that flags where and when significant alterations appear, whether those are shifts in vegetation, newly built structures, or other surface transformations. To give you an idea of scope, the raw scenes are already orthorectified and radiometrically corrected. What I’m missing is the machine-learning layer that will take two (or more) aligned images, learn the patterns of normal variability, and then output clear, georeferenced change masks and summary statistics. Key expectations • Model architecture, trainin...

Project Description I am looking for an experienced Windows/Java developer to develop a very lightweight Windows EXE application for remote system management. The application should be optimized for low resource usage, with a target executable size of approximately 2–3 MB if technically possible. Required Features 1. Simple/Minimal Installation • No complicated infrastructure or installation process. • Prefer a simple standalone EXE. • No visible front-end/UI is required for the client application. • The application should operate in the background. 2.

I’m forming a small founding team and want a business partner whose strengths lie in intermediate-level backend development. You should be comfortable building reliable, scalable services in Python, from designing RESTful APIs and data models to deploying on a modern cloud stack. This is a partnership, not a one-off contract: you’ll help steer architecture, set coding standards and share in the product’s success. While Python is essential, experience with Java or Node.js would be a welcome bonus, not a requirement. First, we’ll co-create a concise technical roadmap; next, you’ll lead the build of an MVP service layer we can demo to early adopters. If you’ve recently shipped a Python backend and are eager to grow something from the ground up, let&rsqu...

I still have a working copy of our old “export” utility--a small .NET Windows Forms program that pulls voice recordings from our recorder software through its SDK--but the original source code is gone. I need someone who can decompile that executable, clean up the recovered code, and then refactor the tool so it runs purely from the Windows command prompt. Instead of the current dialog box, the new build must accept: • a start time and end time parameter that define the export window • a list of one or more phone extensions to filter the recordings Everything else about the workflow stays the same: the program will talk to the recorder SDK, fetch the selected recordings, and drop the files into a local folder on the same server where the recorder software already ...

I need a streamlined workflow that takes every contact-form submission from my existing website, drops the data straight into Airtable, and immediately assigns the enquiry to the practitioner who covers that postcode. Once matched, the practitioner must receive the details by WhatsApp with two quick-reply buttons: Accept or Decline. Their tap should update the Airtable record in real time so I can see at a glance which requests are confirmed and which need reassignment. After a response, the system should: • send a short follow-up asking whether the appointment actually went ahead (or, if you think a live calendar link is cleaner, auto-create the appointment instead and skip the follow-up) • log the outcome in Airtable for reporting and invoicing At month-end I want ...

I have an existing database that I need surfaced through a Laravel-based web portal. The application should let me log in with role-based permissions and then display the stored data as interactive charts, classic tables, and quick-view graphs. Here is the workflow I have in mind: after logging in, an Admin (full rights), Editor (limited CRUD), or Viewer (read-only) can browse to a section that lists users, devices, channels, and roles. From there we must be able to add, edit, or deactivate any of those records without leaving the app. The same roles also govern which export buttons are visible, so staff only see the options they are allowed to use. When someone chooses to export, the system will generate downloadable Excel or CSV files on the fly. I don’t need PDFs for now, ju...

We operate a fully–automated share-market desk from our office built in our residence in Sunder Vihar, West Delhi, and we need a systems-minded engineer beside the servers every trading day from 8:45 AM to 3:45 PM. The role revolves around keeping multiple Python algos, broker APIs and twin infrastructures (local rack + AWS EC2) running smoothly through the entire Indian market session. Each morning begins with launching and verifying every Python script, confirming token validity across all connected broker platforms, and checking that our cloud mirror is in sync so the secondary environment can take over at a moment’s notice. During live hours you will watch order flow, positions, P&L and latency, jump on API disconnections, restart any failed program, and document the s...

I’m looking to have a dedicated software tool built that streamlines data analysis for everyday business use. I specifically need a standalone desktop or cross-platform application rather than a website or mobile app, so please focus your solution accordingly. The goal is to load structured data (CSV, Excel, or a simple database), explore it quickly through filtering and pivot-style summaries, run common statistical or machine-learning routines, and then export clean visual or tabular reports. You’re free to choose the tech stack you feel delivers the best user experience—Python (PyQt, Tkinter, or Electron with a Python backend) or a modern compiled language such as C#/.NET or Java are all acceptable. What matters is that the interface remains intuitive for non-technical...

I need a pro who can walk me through creating a brand-new eBay developer account and make sure it is fully activated with production keys. My sole goal is to pull sold-price data via the eBay APIs, so once the account is live and the keys are confirmed to work in a quick test call (Postman or similar), your job is done. What I expect from you: • Clear, step-by-step guidance—screen-share or concise written instructions—covering registration, application creation, sandbox verification, and production key request. • Troubleshooting along the way if eBay flags anything or asks follow-up questions. • A brief demo call to prove the keys return sold-price results.

I keep all of my operational data in an Excel workbook and need a reliable way to move each row—both text and numbers—into a form inside a custom web application. Right now it’s all manual key-strokes; I want a script or small utility that can read the spreadsheet, match each column to its corresponding field on the site and submit the record automatically. The workflow is straightforward: open the sheet, loop through every populated row, log in to the web app (single username/password), fill the form, submit, then continue to the next row until the sheet is done. Mixed data types appear (dates, currency, free-text notes), so field-level validation and basic error handling are essential. A simple progress log—ideally a .csv or on-screen report—will let me see...

I’m working with a large collection of numeric datasets stored in CSV files and need them professionally cleaned so they’re ready for downstream reporting and analysis. The files contain only numbers—no text labels beyond the headers—yet they still suffer from common issues such as stray characters, inconsistent decimal formatting, empty rows, and duplicate records. Your job is to open each CSV, identify and correct every inconsistency, and return a set of error-free files that preserve the original column structure. Alongside the cleaned data, include a brief change log that lists what was fixed (e.g., “removed 27 duplicate rows in ”, “standardised thousand separators”, etc.) so the transformation is fully transparent.

I run several Django-based web applications that need ongoing feature development and maintenance. To keep up with our roadmap I’m looking for a developer who is comfortable settling in for the long haul, communicating clearly, and shipping production-ready code on a steady cadence. The immediate focus is on three areas that touch nearly every part of the stack: • Multi-factor user authentication – think TOTP, backup codes, and recovery flow all wired into Django’s auth system without breaking existing sessions. • Payment integration – we currently prototype on Stripe and will move to live transactions once the flow is stable, so expect webhooks, retries, and clean error handling. • API development – new and refactored REST endpoints power...

I have a CSV that holds between 1,000 and 10,000 phone numbers and I need the matching Telegram usernames for each one. Along with the username, please also capture the visible profile name; no other profile details are required. The workflow I picture is straightforward: you read the CSV, query Telegram through an API-friendly library such as Telethon or Pyrogram, respect any rate limits or privacy constraints, and return a clean file (CSV or XLSX) with three columns: phone number, username, and profile name. A brief read-me that explains how to run the script and obtain the same output on my side will complete the hand-off. Accuracy matters more than speed, so build in proper error handling and logging so I can track numbers that could not be matched.

I need Microsoft RMS Store Operations to hand transactions seamlessly to VIPay and route them to our Ingenico Lane 3000 terminals. The scope is narrow and clear: real-time transaction processing only—no inventory sync or back-office reporting. The integration must: • Launch from the standard RMS tender screen and pass sale totals to VIPay • Drive the Lane 3000 for EMV chip, mag-stripe and contactless payments • Return an approved/declined response to RMS and post it to the receipt journal Supported transaction types are credit and debit, and we must clear Visa/MasterCard, American Express and Discover through VIPay’s gateway. Please build whichever RMS add-in or external helper service you prefer, so long as it installs cleanly on our .NET RMS environm...

I need a complete WhatsApp Business API setup that focuses on turning incoming contacts into qualified leads. All outbound messages will be promotional offers, and the sequence has to adapt automatically to each user’s engagement level—high‐engagers get richer offers and follow-ups, colder prospects receive gentler nudges. Here’s what the job breaks down to: • Connect and configure the WhatsApp Business API with my existing CRM so every new opt-in is captured instantly. • Build a simple yet flexible tagging or scoring logic that ranks contacts by how often they open, click, or reply. • Create message templates (text, image, or button) for the initial promo, follow-up, and re-engagement stages and submit them for Meta approval. • Set up an auto...
