What I'm looking for

I seek impactful frontend roles where I can own end-to-end features, drive architecture and design-system work, optimize real-time performance, mentor teams, and collaborate in fast-moving product environments.

I am a Senior Front-End Engineer with 8+ years building and scaling performance-critical, data-intensive SaaS applications, specializing in React, TypeScript, and real-time UI architectures.

I have led frontend architecture and design-system initiatives, owned features end-to-end, and optimized frontend performance for high-interaction products using tools like Vite, Next.js, React Query, and modern testing suites.

I collaborate closely with backend engineers and product teams in fast-moving environments, mentor junior developers, and focus on scalable, maintainable frontend systems that deliver excellent UX for power users.
