About

Professional summary

I am a Frontend Tech Lead with 7+ years of experience building and scaling production React applications. I currently own the full frontend platform at Vidalytics, where I lead a cross-functional team, drive architectural decisions, and keep feature delivery moving while modernizing the codebase.

I specialize in turning legacy frontend systems into maintainable, scalable products. In my current role, I lead the Core team, oversee app stability and performance, and help shape the technical direction for subscriptions UI, Smart Vids, integrations, and account settings.

I have led major modernization efforts, including a migration from CRA/Vite to rsbuild that significantly improved build speed and reduced CI time. I also established Zustand as the global state standard, reduced unnecessary re-renders, and introduced clearer engineering standards and migration paths for the team.

Previously, I owned the migration of a legacy Angular application to React 18 and TypeScript, delivering the rewrite incrementally without interrupting feature work. I also introduced key tooling and practices such as pnpm, React Query, Sentry, Mixpanel, and improved linting and component architecture across the codebase.

Earlier in my career, I worked at GlobalLogic on a large-scale OTT streaming platform, where I built responsive React components, improved page load speed, and contributed to new streaming features that increased user engagement. I also started as a freelance Junior React Developer, handling client communication and delivering interactive UI solutions.

I value engineering quality, clear communication, and practical decision-making. I enjoy mentoring engineers, improving team processes, and translating complex technical trade-offs into actions that stakeholders can confidently support.
