Frontend engineer with 4+ years building production React applications. Most recently I worked on a real-time trading platform where I cut a critical view's memory usage from 1GB to ~350MB through React re-render profiling, state architecture redesign, and aggressive component decomposition, the kind of work that's only visible when something catches fire and someone has to fix it.
Remote-first since day one. I've shipped for teams in Indonesia, London, and Paris (Habilis, Equisafe), collaborating async across UTC+0 to UTC+7. At Habilis I led a small frontend team building a B2C match-making product end-to-end.
What I'm strong at: → React performance optimization (react-window, react-scan, profiler-driven debugging) → Real-time UIs at scale (WebSocket feeds, virtualized lists, complex drag-and-drop) → Modern Next.js patterns (App Router, server actions, RSC) → TypeScript, Tailwind, Zustand, Supabase
Outside of client work, I teach 1,000+ developers on TikTok, React patterns, performance debugging, and developer tooling.
What I'm looking for: Senior frontend role at a remote-first international company.
If you're building something I'd find interesting, DM is open.
