Me #

Hi there! I’m Mathéo, 19, a third-year computer science student at Epitech Nancy, France.

I build software for places the industry usually skips: clinics with no reliable power, medical workers with no internet, situations where “just use the cloud” isn’t an option. It didn’t start as a plan. I read about a hospital in Bhutan whose new patient records system fell over on launch day because the network couldn’t take the load, and I couldn’t stop thinking about it. So I built ZamSync. Then I kept noticing the same kind of gap elsewhere and built MenSung. I’m not a great marketer and I don’t pretend to be one, I just try to build the thing and be honest about why.

I’m looking for a part-time position, two days a week (Thursdays and Fridays), from September 13th 2026 through March 1st 2027. It’s a structured part of third year at Epitech, not a maybe. If you’re building something that matters and want a developer who cares about the whole stack, not just the parts that are fun, I’d like to hear from you at matheo.delbarre@epitech.eu.

Outside of code, I play chess, slowly, not particularly well, and I can’t seem to stop.

What I’ve worked on professionally #

Five months at AT7 Système (Aug to Dec 2025), porting a 25-year-old internal WinDev system to the web for technicians working on a locked-down industrial site where they couldn’t install anything. Real users, a legacy database, a vendor API throttled on purpose, and a same-day compliance deadline that didn’t care about any of that.

Read the write-up: Their API was throttled on purpose, and I had to route around it

Security #

Top 5 out of 90 in Epitech’s binary exploitation CTF: stack and heap overflows, GOT overwrites, ROP-style chains, reverse engineering against custom challenges. Top 7 out of 149 across campuses on OWASP Juice Shop, 119 challenges solved: XSS, SQLi, broken access control, crypto, business logic flaws.

What I’m building #

Offline-first software for places where the internet, the hardware, or both, cannot be assumed: ZamSync, a sync engine for clinics in Bhutan that run on 2G and lose power mid-transfer, and MenSung, an offline medication interaction checker for medical workers in war zones, refugee camps, and rural clinics.

See the Projects page for demos and write-ups on both.

The blog #

This is my personal blog where I share thoughts on software engineering, devops, and side projects.

It is built with Hugo and the Congo theme.
