Part-Time Developer Needed for Existing Web App Debugging & Pilot Support

We’re looking for a reliable part-time developer to help support an existing web application that is already built and being used by real users. The main focus right now is debugging, stability, and pilot support. We are not looking to rebuild the app or add major new features immediately. The priority is making sure the current functionality works properly and that the app is reliable for users. You’ll help with: --Fixing bugs in the existing app --Testing current features and workflows --Debugging issues related to loading, chat, uploads, and general app performance --Reviewing the codebase and helping clean up foundational issues --Supporting the app during an upcoming pilot --Helping with future feature requests once the app is stable We’re looking for someone who is comfortable jumping into an existing codebase, working independently, and communicating clearly. Helpful experience: --React / Next.js --Node.js or backend APIs --GitHub --Vercel or similar deployment tools --Authentication, uploads, or chat features --Maintaining or debugging existing web apps Time commitment is around 15–20 hours per week. To apply, please share a quick summary of your experience, relevant projects you’ve maintained or debugged, your weekly availability, and whether you’re open to a fixed monthly arrangement.
