Project description:
"My production build is suffering from sluggish screens and a few stubborn feature-level bugs, so I need an experienced mobile developer who can work on both iOS and Android code bases, track down the performance bottlenecks, and squash the faults that are tripping users up.

At the same time, I want to give the interface a fresh feel. The navigation flow needs to be more intuitive, the colour palette cleaner, and the buttons and icons updated so the whole experience looks consistent and modern across devices. If you’re comfortable refactoring code and then jumping straight into redesigning UI components—whether directly in the native projects or via Figma/Sketch first—this job is for you.

Deliverables
• Optimised, crash-free builds for iOS and Android
• Updated source code with clear comments on fixes and performance gains
• A redesigned navigation structure, refined colour scheme, and revamped button/icon set implemented in the app (plus design files if created externally)

Once everything is stable and the new look is live in TestFlight and an Android testing track, we’ll do a quick round of feedback before final sign-off." (client-provided description)
