What I'm looking for

I seek a hands‑on mobile development role (Android/Flutter) at an Agile product team where I can own features, mentor peers, and drive reliable releases.

I am a Mobile App Developer with five years' experience building and maintaining native Android and cross‑platform Flutter applications for POS, live streaming, e‑commerce, automotive, and transportation clients. I have delivered 15+ apps adopted by thousands of users and fleet vehicles, and I regularly apply MVVM, Jetpack libraries, Kotlin, Dart, Firebase, and REST APIs to create scalable, testable solutions.

I work effectively in Agile/Scrum teams, collaborate with remote developers, and take on project coordination and client communication responsibilities when needed. Highlights include implementing offline‑first Room databases, integrating Agora for live sessions, reducing crash rates via Firebase Crashlytics, and managing releases and pull requests across multi‑developer teams.
