Led a team of 15 developers in end-to-end development of a cross-platform, self-custody Bitcoin mobile wallet (Bitcoin Keeper) for iOS and Android using React Native, growing the user base to over 2,000 active users. Pioneered the integration of Rust with JavaScript via FFI, enabling high-performance native Rust interactions in a React Native environment to enhance on-chain transaction security and privacy with coin-joins. Engineered secure communication with hardware wallets (Coldcard, Tapsigner, Trezor, Ledger, SeedSigner, etc.) via air-gapped communication. Implemented Tor-based private browsing, node management, multi-signature and taproot transactions, in-app subscriptions, and coin-join protocols. Streamlined organization-wide software development by establishing a unified code style guide, simplifying technical architecture, and advancing CI/CD pipelines with Fastlane and App Center. Elevated code quality over a bi-weekly development lifecycle by introducing automated static analysis tools (ESLint, SonarQube) and conducting code reviews, resulting in a 30% reduction in production defects across the React Native codebase for both iOS and Android platforms.

Architected and delivered a secure mobile application for a B2B platform that turns Gmail into a customer support platform, serving over 10,000 teams. Led the mobile development from the ground up using React Native and Gmail APIs, owning the full feature lifecycle from design to deployment on the App Store and Play Store. Architected the app's state management using Redux and Redux-Saga and engineered real-time UI updates using WebSockets. Implemented offline-first capabilities using Realm for seamless data sync. Automated the entire build, test, and deployment process using Bitrise and GitHub Actions.
