I have an existing web application built using an AI website builder (Creo). The UI and overall user flow are already designed, and I have the full exported source code and GitHub repository. However, several core features are not functioning correctly and need to be debugged, completed, and made production ready. I am looking for an experienced full stack web developer who can: Review the current codebase and architecture (front end and back end). Fix broken or incomplete functionality so the existing flows work end-to-end. Implement missing logic for key features (forms, data handling, API calls, etc.). Improve stability, performance, and error handling. Set up a clean Git workflow and help prepare the app to be easily maintained going forward. Tech stack / skills: Strong JavaScript experience (front end web apps). PHP experience for backend or server-side logic. Solid understanding of modern web application development. Comfortable working with an exported codebase (not starting from scratch). Ability to read existing flows, debug issues, and propose better implementations where needed. What you will get from me: Full exported source code of the current web app. GitHub (or similar) repository access from day one. Clear list of known issues, missing items, and priorities. Regular feedback, clarifications, and milestone-based tasks. Ideal candidate: Has previous experience fixing or completing partially built web apps. Communicates clearly in English and is available for regular updates. Can work independently but also ask questions where requirements are unclear. Can propose realistic timelines and is transparent about progress and blockers. Project details: Hourly engagement, budget range: 2–8 USD/hr. Approximate duration: 1–3 months, starting as soon as we identify the right developer. Please share: A short summary of similar web app debugging/completion projects you have done. Links/screenshots to previous work. Your proposed hourly rate within the given range and approximate weekly availability. Write “READY TO FIX YOUR APP” at the top of your bid so I know you read the description.
