I have an operational platform built around a FastAPI backend and a React-based web frontend. The core foundations are in place, but I now need a reliable local partner in Noida to carry the project over the finish line and into the mobile space. Backend My FastAPI services are live, yet they still need performance optimisation, a few new endpoints and some lingering bugs resolved. Clean, well-documented code and test coverage are a must so future iterations remain painless. Web Frontend The React application already runs in production. The next sprint centres on adding new features while simultaneously lifting the overall experience with UI/UX refinements, stronger mobile responsiveness and a refreshed visual identity that matches our brand guidelines. Mobile Apps Once the web work is stable, I want the same feature set delivered as native-quality apps on both iOS and Android. I am open to React Native, Flutter or another modern cross-platform approach if it keeps parity with the web codebase and streamlines ongoing maintenance. Local Collaboration Because past remote engagements cost me valuable time and money, in-person trust matters. I expect regular face-to-face syncs in Noida for planning, demos and quick problem-solving. If you are nearby and can commit to transparent communication and predictable delivery, we will get along well. Key Deliverables • Optimised, bug-free FastAPI backend with additional endpoints • Enhanced React web app featuring new functionality and upgraded design • Cross-platform mobile applications mirroring web features, ready for App Store & Play Store submission • Clear documentation (API, setup, deployment) and hand-off support Please share links to comparable work—especially projects that combine FastAPI, React and mobile builds—and indicate your availability for on-site meetings in Noida. I’m ready to start immediately with the right collaborator.
