Edouard Baillot

Full-stack engineer — product, AI, and automation

Open to contract and full-time roles

Full-stack engineer who ships from product down to infrastructure. By day I build internal systems at La Poste / Colissimo (Java, Angular); the rest of the time I run four live SaaS products I designed, built, and operate myself (Next.js, PostgreSQL, LLM integrations). Unusual route in: ten years in the French Foreign Legion, then École 42, then product engineering.
