What I'm looking for

I'm looking to build fast, accessible, high-quality web products where I can deliver polished frontend experiences, solve performance challenges, collaborate with clients and teams, and mentor other engineers.

At 6sense HQ, I build reusable, accessible UI systems and high-performance storefronts with React, Next.js, TypeScript, and Tailwind CSS.

I've delivered 90+ Lighthouse scores using SSR, SSG, and ISR, and improved page load times by up to 30% through lazy loading, code splitting, and deferred components.

I’ve also architected real-time chat and video calling with Agora and Next.js API routes, implemented Socket.io and SSE updates, and strengthened observability with PostHog and Sentry.

Earlier at The Celltech, I integrated Stripe and RESTful APIs while building web applications in a six-person team. I enjoy turning Figma designs into responsive, pixel-perfect, SEO-friendly interfaces and mentoring engineers through clean-code guidance.
