Hi, I'm
Clément Vallois
Backend Developer
I spent 5 years managing IT projects at Ayvens and writing functional specs. Good experience, but I wanted to build things rather than steer them. Now I design APIs with NestJS and TypeScript, with a real sense of what happens on the business side.
Node.js · NestJS · TypeScript · PostgreSQL · Docker
// Backend
NestJS APIs with Fastify, TypeORM, and PostgreSQL. Unit and integration tests, green CI.
// Architecture
DDD with strict domain / application / infrastructure separation. Interface-based contracts, zero framework dependencies in the domain.
// DevOps
Docker Compose, GitLab CI, GitHub Actions, AWS EC2 with Nginx. SonarQube for quality tracking.
