What I'm looking for

I seek roles where I can lead frontend architecture and performance initiatives, mentor engineers, and drive scalable systems in cross-functional teams while improving user-facing metrics and release stability.

I am a Senior Frontend Software Engineer with 15+ years building scalable, enterprise-grade web applications and leading frontend modernization initiatives. I specialize in React 18, Next.js, Redux, TypeScript, and frontend architecture including component libraries and design systems.

I have implemented Server Components, Streaming SSR, and ISR strategies while optimizing Core Web Vitals—reducing Largest Contentful Paint by 35%—and established frontend observability practices with Sentry to reduce production regressions by 40%. I integrate REST and GraphQL APIs, influence caching and authentication strategies, and deliver measurable performance improvements for thousands of users.

I mentor engineers on concurrency, accessibility, and performance, drive cross-team architecture decisions, and continuously improve testing and CI/CD practices to increase release stability and maintainability.
