About Thibault

I design SaaS products end-to-end with Next.js, TypeScript, and Go.

I am co-founder of OpenStatus.dev, an open-source uptime monitoring platform used by developers worldwide. Before that, I was the first tech employee at Roundtable, where I built the entire platform from scratch.

This journey has given me a unique profile: delivering production-ready code, quickly, with a real focus on infrastructure, performance, and developer experience. I'm comfortable taking a feature from Figma to production, making the right trade-offs, and keeping the code maintainable as the team grows.

Daily Stack: Next.js, TypeScript, Tailwind, Shadcn, Drizzle, Go, Vercel, SQLite/Postgres.

Good fit for:
- Early-stage startups building their v1 or passing the MVP stage
- Teams that want quality, not just volume
- Founders looking for a senior partner who knows how to say no, not just an executor
