What I'm looking for

I want to build and own Flutter mobile products end-to-end—ship reliable releases with strong CI/CD, testing, and observability—while working on real-time, secure fintech or web3 features at scale.

I’m a Flutter Engineer with 3 years building production-grade Android/iOS apps, where I take ownership of releases end-to-end—from CI/CD automation to App Store/Play Store rollouts and code reviews.

Across web3 trading, fintech, and gaming, I’ve integrated secure cross-platform authentication (Firebase Auth, Google Sign-In, Apple Sign-In) and built real-time systems using WebSockets and performance optimization practices backed by strong testing coverage with unit and widget tests.

I thrive on complex problem solving—shipping on-chain prediction markets and perpetual futures trading with sub-300ms order flows, improving production stability with Sentry and analytics, and accelerating delivery through AI-assisted workflows (Cursor, Claude, GitHub Copilot).
