Our hiring pipeline is filling up with senior-level mainframe candidates and I need the interviews handled by someone who speaks their language. The sole purpose of these sessions is to validate deep technical skill—no culture chats or HR-style screenings—so each call must drill straight into COBOL programming, JCL mastery and hands-on DB2 management. Here is what I need from you: • Craft a concise yet challenging question set that uncovers real‐world competence in those three areas. • Run remote, one-on-one video interviews (I’ll schedule them) and keep them within a 45-minute window. • Score every candidate against clear criteria and deliver a brief written report summarising strengths, gaps and overall hire/no-hire advice within 24 hours of each c...

I need a desktop-based tool that can speak the native, proprietary languages of three different DCS families—ABB 800xA, ABB AC450 and Mitsubishi DIASYS Netmation—and then use those links to send remote-control commands. The scope centres on building (or integrating) protocol drivers for each system, proving that they can log on, browse the tag database, write set-points and issue start/stop or mode-change commands exactly as an operator console would. Once the drivers are stable, they have to be wrapped in a single Windows desktop application with a clean UI where I can select the target DCS, pick a tag, send a command and view a confirmation/echo. Acceptance is straightforward: if the test script can alter a value or state on each DCS and the change is visible on the native ...

I want to build a full-stack desktop application that enables pharmacists in my store to manage daily operations from a single, intuitive interface. The core modules I need are: • Inventory management that keeps real-time stock levels, tracks expiry dates, and provides low-stock alerts. • Prescription handling with quick patient lookup, doctor information capture, and automated interaction checks. • Sales reporting that summarises daily and monthly revenue, highlights best-selling medicines, and exports to CSV or PDF. The entire workflow—from receiving a prescription to final sale—has to feel seamless on a desktop computer, so performance and an offline-friendly architecture are important. A clean UI/UX, role-based access, and straightforward installation o...

I need a self-contained Windows application that can handle end-to-end payouts through Indian banking rails—specifically IMPS and NEFT, nothing else. The tool must run locally on a Windows machine without relying on any existing ERP or web platform; everything from beneficiary management to transaction initiation and status tracking should sit inside this standalone executable. Core flow I have in mind: • Secure login for authorised staff. • Simple screens to add or import beneficiaries, store IFSC and account details, and mark KYC status. • Batch or single-click payout execution over IMPS or NEFT, selecting the rail automatically by cut-off time or allowing a manual toggle. • Real-time or near real-time acknowledgement retrieval and a clear ledger/history pa...

I need a small AI-driven workflow that automatically sends a single SMS containing only our review link the moment a job is marked “completed” in our system. The trigger is the service-completion confirmation event—no timers or manual pushes. The scope is straightforward: • Detect the completion confirmation coming from our platform (API or webhook can be exposed). • Generate and dispatch an SMS that includes the review link (no customer name or service details in the text for now). • Log basic send status so I can audit deliveries and retries. • Package everything so I can adjust the review link or plug in additional text fields later if needed. Twilio, AWS SNS, or a similar gateway is fine as long as delivery reporting is reliable; feel free to su...

Looking for a part-time Android developer to help polish and extend an existing production app (Kotlin, Jetpack Compose, Hilt, Room, multi-module Gradle). I handle product direction and design; you handle execution using AI coding tools (Claude Code / Cursor) to move fast, then verify the output yourself before shipping. You should have: 2-3 years Android dev, strong in Kotlin + Jetpack Compose (real production apps, not just courses) Comfortable with Hilt, Coroutines/Flow, Room Active daily user of an AI coding assistant (Claude Code, Cursor, Copilot) — know how to prompt it AND how to catch when it's wrong Can follow a design spec exactly, no improvising on UI Own an Android phone to test on (budget phone like Redmi/Realme is a plus) Work: Bug fixes and feature builds from a...

I need a seasoned C/C++ developer to craft a Direct Memory Access application that runs reliably on Windows. The core requirement—beyond solid performance and stability—is an integrated automatic-update system so users never have to reinstall manually. We can cover the finer technical points one-on-one over Discord or email, but in broad strokes here is what will move the project forward: • A fully working Windows DMA executable written in C/C++ • An update mechanism that checks, downloads, and patches seamlessly • Clean, well-commented code that future developers can extend When you reply, please include: – A couple of DMA-related or similarly low-level projects you have completed – Your estimated timeline (no hard deadline on my side,...

I need a full-source-code recreation of the classic Visual Basic 6 development environment, internally referred to as “Visual Basic 7.” My main goal is to open and run existing VB6 projects with zero functional loss, while adding modern support for .png images in both the Image and PictureBox controls. Core requirements • Replicate all standard VB6 user-interface components, complete with property windows, toolbox, code editor, and form designer. • Preserve the original event-driven programming model so legacy code behaves exactly as it does in VB6. • Ensure ActiveX controls register and load seamlessly. • Add built-in .png file selection and rendering for Image and PictureBox controls (no external converters—the controls must handle tra...

I already have a two-screen interface finished in Squareline for my ESP32-CYD based nervoscope. All component IDs and events are set; what I am missing is the Arduino IDE firmware that brings it to life. Main screen • Shows battery level (%) • Rotates a gauge needle toward whichever of the two RTD probes reports the higher temperature Settings screen • Slider-controlled probe/needle sensitivity • Dark / light theme toggle • Information panel toggle • Screen-brightness control • Temperature unit toggle with Celsius as the default • Sleep-timeout selection Your task 1. Import the finished Squareline project, wire it to LVGL (or the display library you prefer) and produce a clean, well-commented .ino sketch. 2. Read both RTD sensor...

We're hiring a part-time sourcer to find and pre-screen US-based software developers for us. This is an ongoing, long-term role — not a one-off project. How this works: You handle the first stage. You find candidates, reach out, and run a short screening call to filter out anyone who isn't a fit. You then hand us a shortlist. Our team runs the technical interviews and makes the hiring decisions. You are not responsible for closing hires — your job is to make sure that by the time a candidate reaches us, they're worth our time. Budget: $300–600 USD/month, paid bi-weekly or monthly. Final rate depends on experience and weekly hours. We're open to raising this over time based on results. What you'll do - Source US-based developers via LinkedIn an...

I need our existing RDT, COA Chemical, COA QC and LIMS Suitability applications—currently running at the J. Mitra head office—cloned to two branch locations: J. Mitra IMT (606-607) and J. Mitra IMT (604-605). All functional logic, screens and workflows remain untouched; the only modification is the company address that appears inside each system. Once the replication is complete, both branches must operate exactly as the head office does today, sharing the same data integrity, user roles and reporting capabilities. Deliverables • Fully operational copies of all four applications on the branch servers/workstations • Address updated wherever it is surfaced in the UI or printed outputs • Migration/installation records and a brief hand-over note so in-house ...

My current web application is already in production, but it needs a thoughtful round of improvements to reach the next level. This is a medium-sized engagement: big enough to require structured planning and solid engineering practices, yet focused enough that we can measure clear before-and-after gains. Scope The codebase, infrastructure, and basic feature set are in place. What I need now is a systematic upgrade that tightens the user experience, polishes rough edges, and removes the performance bottlenecks that have crept in as usage has grown. While the primary emphasis is on enhancing what already exists, I’m open to sensible suggestions that add value—whether that’s refining the interface, optimising queries, or refactoring key modules. Collaboration Style You&...

Scope • Build a clean, stable Windows executable (native Win32, .NET, or an appropriate cross-platform framework compiled for Windows only). • Keep the interface minimal and intuitive; a simple GUI or well-documented CLI is fine as long as the user flow is clear. • Include basic error handling and a brief user guide or in-app help. What I’m looking for in your bid • Proposal proyek yang terperinci: outline your chosen language or framework, high-level architecture, and the milestones y...
