I’m a fourth-year computer science student (ITI) at INSA Rouen Normandie, a French engineering school. Most of my projects started from a need around me: registrations for a charity run, peer tutoring in my department, a game server that lagged on event nights. I built them, shipped them, and I still run them.
I also do offensive security in competitions, which has changed the way I review my own code. And I’ve maintained open-source projects since 2020. My articles are written in French.
I’m looking for a 10 to 12-week internship in infrastructure or security, from late June to early September 2027, in France or abroad. The easiest way to reach me is romain@leprevost.dev.

Personal project
On event nights, our community game server moves to a cloud VM rented by the hour, then goes back to its small VPS. Lever, an orchestrator I wrote in Go, handles the switch. Cost: about €6.50 a month, versus €140 for a dedicated server.

Technical lead
Purple Rouen is a charity run organised by students. I built its registration website and ran it up to race day: online payment, automatic checks of the runners’ medical certificates, QR-code tickets. 745 runners registered over two editions, €7,073 donated.

Offensive security lab
A lab I built to reproduce a common mistake on self-hosted Git forges. You start from an unprivileged SSH account and end up root on the Docker host, through open sign-up and a CI runner that mounts the Docker socket. The write-up covers each step and what would have stopped it.

Runners type their bib number and get their photos: a YOLOv8n model trained on my own annotations, then OCR. Over 1,200 bibs indexed.

The student union’s website, which I built and administer: shared calendar and club news.
Since 2020
A Java add-on connecting Skript game servers to MongoDB, maintained since 2020 and used by over 150 servers. Along the way I reported a regression in MongoDB’s official Java driver, since fixed.
2023 – 2026
Written for my own needs: encrypted MongoDB backups to S3, OAuth2 clients in PHP, hosting panels behind Cloudflare Zero Trust.
