About

I'm a Senior Software Engineer and Tech Lead specialized in React Native, with hands-on experience across React and Node.js. My job is half engineering, half leadership: I turn product requirements into clear, actionable work, assign it to each person's strengths, unblock the team every day, and own the release cycle from versioning to store submission.

Over the past year I led my team's adoption of AI-assisted engineering. Average velocity doubled, web and mobile specialists now ship on both platforms, and our manual QA team is moving to test automation. I care about the people side as much as the code: onboarding new engineers until they're independent, and keeping the team steady when a ticket gets overwhelming.
