What I'm looking for

I seek impactful frontend or full-stack roles where I can shape architecture, mentor teams, and deliver high-performance, maintainable web products.

I am a Senior Frontend Engineer with 7+ years building scalable React applications, performant web experiences, and long-lived frontend systems. I focus on maintainable architecture, performance optimization, and design systems that enable teams to move quickly and safely.

I've designed end-to-end solutions as a co-founder and full-stack developer, shipped production web platforms, a Chrome extension, and engineered backend APIs and auth systems using technologies like Hono, Drizzle, SQLite, Cloudflare Workers, and better-auth. At CoinMENA I led the development of publishing sites, implemented Next.js ISR, achieved 96+ Lighthouse scores, and integrated headless CMS workflows to empower marketing teams.

I mentor engineers, drive architectural improvements, and bridge design and engineering to deliver polished, accessible, and high-performance products. I'm motivated by pragmatic engineering, testable code, and creating frontend systems that outlive their authors.
