    I’m ready to turn my existing REST API into a polished React Native mobile application. The API is fully documented and the screen designs are complete; what I need now is a clean, TypeScript-based codebase that follows good component architecture and stays as close to pure React Native as possible. Core requirements • Authentication: wire the app to my API using Basic authentication and persist credentials securely. • Navigation & UI: a tabbed interface that presents a master list (pulled from the API) and corresponding detail views, matching the provided Figma files pixel-for-pixel. • Offline experience: cache the entire app’s data locally so users can browse previously fetched content without a connection, with automatic background sync on reconnect...

    We have an existing live bilingual Saudi offers and loyalty platform built with React, TypeScript, Node.js/Express and PostgreSQL. We want to package the existing responsive web platform as one mobile application for both iOS and Android using Capacitor or a similarly suitable WebView-based approach. This is not a request to rebuild the platform in Flutter or React Native. The objective is to reuse the existing React application and APIs while providing a reliable mobile-app experience suitable for submission to the Apple App Store and Google Play. The same application will serve different users according to their existing server-side roles and permissions: - Customer. - Store manager. - Branch manager. - Offer manager. - QR validation employee. - Platform administrator remains primari...

    I already have the trading logic; what’s missing is a solid bridge to Interactive Brokers. Your task is to wire my algorithm to the IB API so that it can: • pull real-time market data without lag, • place/modify/cancel orders instantly, and • query my account and portfolio in the same session. Use the official Interactive Brokers interface—ibapi or a high-level wrapper such as ib_insync is fine as long as the final code is clean, well-documented, and runs on Windows 11 with Python 3.11. I will hand you the existing strategy code and paper-trading credentials. Return a self-contained module, a short usage demo, and a README that explains configuration, key functions, and any edge-case handling. I’ll consider the job complete once I can place a test ...

    I need an AI-driven auto-responder that plugs straight into my email workflow and replies in clear, natural-sounding English using a library of predefined templates I will supply. Here is the core of what I’m after: • When a new message lands in the inbox, the system should detect the intent, choose the correct template, merge any dynamic fields (name, order number, date, etc.) and send the reply automatically—no manual review unless I flag an exception. • I’m working only with email right now, but I’d like the code organized so additional channels such as WhatsApp or Slack could be added later without rewriting the logic. • Templates will live in a file or lightweight database that I can edit myself; the responder should reload them without ...

    I have a fully-formed concept for an iOS e-commerce application and I’m ready to move from idea to App Store listing. I need a developer who can guide the project end-to-end—shaping the user experience, writing clean Swift/SwiftUI code, connecting to the necessary back-end services, and ultimately handling the submission process so the app is live and compliant with Apple’s guidelines. You will start by translating my functional outline into low-fidelity wireframes, iterate into polished UI designs, and then build the production app. Throughout the build we’ll keep each feature shippable, use TestFlight for staged releases, and track issues so nothing slips through the cracks. I’ll provide product requirements and timely feedback; you’ll bring technical...

    Looking for an experienced Full-Stack Developer to help finalize an almost-completed web application and make it fully launch-ready and deployment-ready. The project is already largely built and functional. I am not looking for someone to start from scratch. The main work will involve reviewing the existing codebase, checking that all frontend and backend components are properly wired together, fixing any broken flows, completing unfinished features, improving security, testing the application thoroughly, and preparing it for production launch. The developer should be comfortable with: * Reviewing an existing full-stack codebase * Checking frontend-to-backend wiring * Verifying API integrations * Fixing incomplete or broken functionality * Completing remaining features * Improving auth...

    My production-grade web application currently mixes ArcGIS JavaScript API 3.x and 4.x code. I want the entire front-end moved to the latest 5.x release so I can take advantage of its modern framework, performance improvements and long-term support. Core workflows to preserve • Geospatial data management remains the heart of the app. • Users must still add, remove and reorder layers, change symbology and toggle visibility exactly as they do today. • Interactive maps with pop-ups have to remain responsive and accurate. • Custom widgets and tools (including a bespoke polygon editor that lets users query, create and edit vector features) must be rebuilt or refactored so behaviour is unchanged. Upgrade goals Beyond parity, I’d like the user interface refr...

    I need a cross-platform mobile application that pulls every piece of my call-centre workflow into one place and runs smoothly on both iOS and Android. The main goal is to give each agent a clear, real-time view of their daily objectives, the material they must use, and how close they are to their performance targets. What the app must do • Task management – present an actionable to-do list, allow agents to tick items off, and trigger push reminders before anything slips. • Script uploading – let team leaders or administrators drop new talk-tracks (PDF, DOCX, or plain text) into a web console and have them appear instantly inside the app. • Lead tracking – import leads (CSV or API), let agents update status after every call, and automatically count co...

    I sell digital downloads to a mainly North-American audience and, because of poor credit history, every mainstream gateway I’ve approached has turned me down. I now need someone who already knows the high-risk space to secure a reliable payment processor or merchant account that will actually approve my business and then wire it seamlessly into my Vrio CRM. Here is what success looks like for me: • A live, approved high-risk merchant account (or gateway) that accepts cards from U.S. and Canadian customers. • Full API or plugin integration with Vrio so new transactions instantly create and update customer records—customer management sync is the priority. • Clear, written implementation steps so I can maintain the setup going forward. • At least one e...

The shop is already live on its own platform; what’s missing is the ability to process credit and debit cards smoothly. Must configure with vrio Here’s what I need from you: • Approval for card processing that covers Visa/MasterCard, American Express, and Discover. • Any accompanying payment gateway credentials or API keys so I can complete the technical hookup on my side. • Clear guidance on documentation, underwriting requirements, and compliance steps so the account stays in good standing from day one. If you have established relationships with acquiring banks, PSPs, or high-risk-friendly providers and can walk me through application, KYC, and final inte...
