Freelancer profile translated to English.
Back to original languageAbout Valentin
I build reliable and structured backends for web applications and SaaS, using Node.js, NestJS, or Express, and PostgreSQL.
Whether it's starting a project from scratch or structuring an existing backend, I handle everything that happens on the server-side: API design, database modeling, authentication, role management, CI/CD.
On the frontend, I'm also comfortable with React / Next.js, which allows me to work on full-stack projects without any blind spots between the two layers.
What I concretely bring:
- REST APIs with Express or NestJS
- PostgreSQL modeling with Prisma or Sequelize
- JWT authentication, role management, and route security
- CI/CD setup and Docker containerization
- Third-party API integration (Stripe, Shopify Storefront, etc..)
Whether you are a startup launching its MVP, an SME looking to structure its existing backend, or a founder with an idea to bring to life, if you need a developer capable of handling the server-side, let's talk.
