Project description:
"FULL TIME POSITION MONTHLY
PLEASE READ CAREFULLY ( MUST HAVE 5 YRS SENIOR PROGRAMMER EXPERIENCE) . Please send examples of mobile app developent work

I’m expanding an existing product and need a senior-level developer who can own the mobile side from Flutter UI down to the AWS back-end. The core focus is mobile app development, and the very first milestone is implementing rock-solid biometric authentication (Fingerprint and Face ID) alongside a traditional login flow.

This is a full-time, long-term role, so I’m only considering professionals who bring at least five years of hands-on experience shipping production apps. You should feel completely at home with:
• Flutter and Dart for cross-platform interfaces
• AWS services for hosting, storage, user pools, and serverless functions
• Java for back-end business logic where required
• Modern CSS for occasional responsive web views inside the app

Must work an Eastern Time Zone Schedule

Beyond the initial authentication module, you’ll help refine architecture, build new features, optimise performance, and handle end-to-end deployments. Clean code, clear Git history, and proactive communication are must-haves.

If you’re a proven problem-solver who loves turning product ideas into polished, secure releases, let’s talk about the roadmap and get you set up on the repo." (client-provided description)
