What I'm looking for

I want to build and ship end-to-end React Native products where I can own architecture, security and release pipelines—partnering closely with backend teams and international stakeholders, and using AI-assisted development tools to move fast without sacrificing quality.

I’m a React Native Developer with more than 3.5 years of experience building and shipping mobile applications end to end—from architecture and development to App Store and Google Play release. I’ve worked as a sole mobile developer delivering fintech, crypto exchange, and E2EE messaging apps, balancing product velocity with technical rigor.

In my most recent role, I owned Lps Talk as the sole mobile developer: fixing core E2EE encryption issues (including group message encryption) and delivering WhatsApp-level features like file sharing, message replies, emoji reactions, and Jitsi voice/video calling. I also designed and built the synchronized Lps Talk Web client from scratch, solving real-time sync challenges over WebSocket with offline-first support and a local outgoing message queue.

I’m comfortable leading requirements with backend teams and presenting products to international enterprise clients. I built a white-label multi-brand build system for separate client products, managed complete release pipelines, and supported private-server onboarding via QR code for complete data isolation.

Earlier, I designed and built a fund analysis and investment tracking app for 15,000+ users using bare React Native and Zustand, delivering complex visualizations with Victory Native and React Native ECharts plus deep linking and push notifications. I’ve also contributed across Web3 exchange and wallet development (WalletConnect), built an AI-powered relationship compatibility app with AdMob monetization, and extended React Native products with search, filtering, and real-time availability features.
