I already have a production Flutter mobile app and the full source code sitting in Git. What I need now is a diligent developer who can pull the repo, review the current architecture, and push a clean set of updates that compile without breaking existing functionality. The exact tweaks range from polishing a few screens and tightening animations to squashing some edge-case bugs that have slipped through QA. If, during the process, you spot an opportunity for a small feature enhancement or an easier way to hook in a payment or social login service, I’m open to your suggestions as long as the core timeline stays intact. You’ll hand back: • Updated, well-commented Dart code committed via pull request • A debug build for quick testing and a signed release build ready for the stores • A concise change-log noting every file touched and the reasoning behind each modification Let me know your availability to start, how you prefer to structure milestones, and a rough estimate of the hours you’ll need once you’ve inspected the repo.
