What I'm looking for

I want a remote-first team where I can lead React/Next.js product work—shipping AI and SaaS experiences—while owning frontend architecture, design systems, testing, and performance with distributed engineers.

I’m a Senior Frontend Engineer with 6+ years of production experience building and scaling international SaaS, consumer, and AI-enabled products. I specialize in React, Next.js, TypeScript, frontend architecture, design systems, testing, and performance.

I’ve enjoyed leading distributed teams and shipping remote-first products, from consolidating codebases into monorepos to tightening quality through stronger testing. At HiPeople, I led three frontend engineers, improved testing, and boosted performance.

As Founder & Frontend Engineer at Menuit, I built an AI digital-menu platform from scratch. Previously, at ZYNC, I built the frontend for a Mercedes-Benz EV video streaming app.

Earlier at KleeGroup – Klee Commerce, I built web and mobile frontends, defined design system patterns, and led a delivery team. I hold an MSc in Physics Engineering from CentraleSupélec, and I bring a structured, detail-oriented approach to how products are designed and shipped.
