Software Engineer, Mobile and Backend
I build offline-first, real-time systems that stay correct on unreliable networks.
6+ years of production engineering across fintech, telehealth, e-commerce, IoT, and logistics. Most of my work sits on the boundary between a mobile client and a distributed backend: state synchronization, conflict resolution, secure API layers, and the release pipelines that get all of it to users.
20,000+ active users · 99.5% crash-free · 4.7+ App Store rating · 40% faster deployments · 8+ shipped cross-platform apps
Offline-first correctness. Local-first persistence with SQLite and Hive, background sync, conflict resolution, and reconciliation on reconnect. The app stays fully usable with no connection and converges to a correct state once one returns.
Real-time on hostile networks. WebSockets, MQTT, and WebRTC tuned for low-bandwidth and unstable 2G/3G links, including IoT device registration and energy-flexibility scheduling.
Backend services in Go. Microservices, REST and GraphQL APIs, PostgreSQL and MongoDB, JWT auth with access and refresh tokens, webhook handling, and error-recovery paths for financial operations.
Release ownership. CI/CD across GitHub Actions, Fastlane, and Codemagic, from automated testing through to App Store and Google Play releases. Cut deployment time by 40% at NexaHealth while sustaining a 99.5% crash-free rate.
Leading and mentoring. Led mobile engineering at four companies, ran code review and documentation practice, and taught a project-based Flutter curriculum to 30+ students with a 95% completion rate.
Contributor to go-ethereum, the Go implementation of the Ethereum protocol, and FastLED, a widely used C++ animation library for embedded systems.
