Hi, I'm Stéphane

Full-Stack Developer — Rennes, France

Profile picture of Stéphane Dinahet
Rennes, France
Open to full-stack roles & internships

I’m a full-stack developer focused on clean architecture, secure authentication (JWT, Spring Security), robust APIs and data visualization. I enjoy delivering end-to-end: backend, databases, Docker, and a polished UI.

My current main project is Loto Tracker — a production-grade app that fetches official results, stores them in PostgreSQL/MongoDB, exposes REST APIs, authenticates users with JWT, and visualizes insights with charts.

APIs & Backends

Spring Boot 3 (Java 21), Python, JWT, scheduled jobs

Data & Storage

PostgreSQL, MongoDB, Flyway, SQL/NoSQL models

Front-End

HTML/CSS/JS, Bootstrap, charts, responsive UIs

"

Ship value early, keep it secure, test thoroughly, and iterate with real data.

Let’s build something users love

I’m ready to contribute on full-stack missions, with a focus on reliability, performance and DX.
