About me
Intro
Senior software engineer with 10+ years building mobile and web products across the full stack — from greenfield apps to production systems used daily in the field. My core expertise is React Native and TypeScript, but I operate at the system level: architecture decisions, CI/CD pipelines, design systems, store deployments, team onboarding. I've led mobile products end-to-end as the sole engineer, and scaled them by growing and mentoring the team around me.
