Freelance

The same kind of work, as a freelancer. Web has never been my cup of tea, but working for myself has been a really good experience.

Full-stack, then back-end

ft_transcendance

The board game Onitama, online. I work on the back-end, with others, and a bit of DevOps. It is a pedagogical project of 42 school, the last one of the Common Core.

Nuit de l'Info 2025

A Linux desktop simulated in the browser. I did front-end work and a lot of reviewing. Having to code that much, that fast, in so little time, with so many teammates, is not easy!

TypeScript · team, in one night

cub3D

A Wolfenstein 3D-style raycasting engine. The mathematics behind the ray casting to calculate the travelled distance are really interesting, and so is learning to optimize.

minishell

A reproduction of bash, done by ourselves, with the closest possible support of POSIX. Solving all the edge cases was hell.

webserv

A single-threaded HTTP server, able to parse an advanced Nginx configuration file, and to configure a complete server in C++.

cpp_09

Ford-Johnson sort, visualized. I also made a visualizer directly inside the project to measure result metrics in order to optimize the program as much as possible.

Philosophers

Five philosophers, five forks. This project is about multi-threading and the issue of data races.

Inception

A complete containerized infrastructure. I also learned how to set up monitoring and exporters in Go on my services, in order to have precise metrics.

SpinUp

A full-stack web application in one command. An unfinished project, allowing you to create full-stack applications with customized stacks, in a single command.

Go · CLI

brainfxcker

A Brainfuck compiler. The code is first translated into x86-64 Assembly, Intel syntax (with NASM elf64 format), linked with ld. Optimization and memory management are really interesting.

C

libasm

Some of the libc functions, rewritten in assembly. A good starting project to discover this assembly, and to also understand what happens on the computer.
