Senior Mobile Developer
Hanoi, Vietnam
#OpenToWorkMobile Developer with ~7 years of experience in React Native and Flutter, contributing to large-scale fintech products — from the ATX digital asset exchange (~2M users) to the Finpath stock-analysis app (140K users). Led the codebase migration from React Native to Flutter and built a custom trading chart engine from scratch with Canvas/CustomPainter to replace TradingView — with feature parity to the charts of leading global exchanges (Binance, OKX, Bybit), optimizing render performance and enabling full UI/UX customization per product. Implemented and customized native modules (Android/iOS) tailored to application features. Operated an AI-augmented workflow with Claude Code and Cursor — building rules, skills, and subagents to standardize output and boost overall mobile-team productivity. Collaborated cross-functionally end to end: with Product/Design on UX, with Backend on API/Socket performance, and with Support on fixing bugs from end-user feedback. Career goal: Senior Mobile Engineer / Mobile Tech Lead.
