Our SaaS platform is already live and stable, but the look-and-feel and a good portion of the server logic are about to get a facelift. I have complete wireframes that spell out the new UI flow, colour system, and component hierarchy. Your job is to translate those wireframes into production-ready React JS screens and, in parallel, refactor the existing Python backend so it matches the new routes, data calls, and validation steps—no brand-new features, just a cleaner, faster version of what is there today. Front-end details • Tech stack: React JS (current project uses functional components and hooks). • Expectations: pixel-accurate build from the wireframes, fully responsive, clean state management, and no regression on current performance. Back-end details • Tech stack: Python (the codebase is organised in RESTful services). • Expectations: keep the same feature set, reorganise endpoints where the new UI requires it, improve code readability, and maintain our existing test coverage. Deliverables • Updated React codebase aligned with provided wireframes. • Refactored Python services that plug seamlessly into the refreshed UI. • Migration/upgrade scripts if any database field names change as a result of the refactor. • Short hand-over document and walkthrough call so my internal team can take it from there. I’m happy to run quick review cycles as pieces are completed, and the project can be pushed to our Git repository in milestones so we never drift from the new design. If you have solid experience shipping React front ends and refactoring production Python back ends, let’s get started—our users are ready for the upgrade.
