What I'm looking for

I seek a frontend role where I can own end-to-end product delivery, improve performance and developer experience, and work in a collaborative, impact-driven team.

I am a frontend engineer with a track record of delivering high-performance, production-grade web applications and developer tools across startups and large platforms. I have built core trading features, AI-driven developer tools, marketing products, and large-scale monitoring dashboards using React, Next.js, TypeScript, and related modern stacks, achieving measurable improvements in performance, reliability, and user growth.

My work combines pragmatic engineering with product ownership: I lead requirement reviews, architecture, implementation, and release, and I optimize build systems, observability, and UX. Notable results include zero delivery delays and P0 incidents at a trading platform, a 30k+ user product launch, improved Core Web Vitals and SEO, and an AI code-review tool adopted across 30+ repositories.
