Hi SnapPay team, Flutter developer, 4+ years mobile experience. Most recently sole mobile engineer at a Korean startup — shipped a production Flutter app end-to-end including native channels (Kotlin/Swift), App Store and Play Store releases, and tricky production debugging (token refresh race conditions, concurrent 401 handling). Your scope (UI cleanup, onboarding, API debugging, bug fixing) is exactly the kind of work I've done in production. I'd suggest starting with a 1-week paid audit to identify and prioritize issues before scoping the full engagement — that way we both have concrete data to work from. Based in Korea (UTC+9), async-first friendly, available to start immediately. GitHub: github.com/junmin87 Best, Junmin…Hi SnapPay team, Flutter developer, 4+ years mobile experience.
