Mathieu Soysal — software developer

Development has been my thing since the very start of my studies. What I care about is code that holds up over time — tests written first, boundaries that stay clean, and a pipeline that catches mistakes before I do.

Away from project work I compete in algorithmic challenges on CodinGame, and I build the tooling I wish I had: reusable GitHub Actions for Java and Rust projects, now used by other people’s repositories too.
