Antoine de Veyrac,
fullstack developer with 10 years of experience, React expert and backend architect. I build robust, scalable web, mobile and web3 apps with functional programming (Effect.js), strong typing and event-driven architectures. Feel free to get in touch if you want to work together.

My projects ( Professional )

I believe backend quality decides product quality. I design APIs with dependency injection, typed errors and functional composition, which keeps systems testable, maintainable and ready to scale. From the TypeScript monorepo to automated CI/CD, I hold myself to the same standard on technical rigor as on shipping.
