Projects

MEP stands for “Mega Embedded Project”: a series of small projects to learn embedded development, ESP32 boards and building circuits around a microcontroller.

For each exercise, I write the program in C with ESP-IDF, build the circuit and draw its schematic. Some exercises are also done without a framework, to understand what happens underneath.

One repository per exercise. I have only just started: so far, a blinking LED.

A compiler that turns a Brainfuck program into an executable binary. The program is parsed, translated to x86-64 assembly (NASM, Intel syntax, elf64 format), then linked with ld.

The goal: understand how assembly works at its core, and learn new concepts along the way.

Rewriting some libc functions in assembly: my first steps into this fantastic world.

I added a unit-testing framework in C to test my functions end to end, and followed a TDD (Test Driven Development) approach.

Rebuilding a hashmap in C under time-complexity constraints. Some tasks are optimised with inline ASM, using SIMD to process several values in a single operation.

A solution to the dining philosophers problem, using multi-threading. I learned about mutexes, data races and sharing resources between threads in C.

A unit-testing framework for C, written in C. Each test runs in a child process, which meant catching signals and checking return values.

A replica of POSIX Bash, strictly following its syntax, execution, redirections, permissions and environment variable handling.

We even added a few themes to customise the prompt.

An HTTP server modelled on how Nginx basically works: full parsing of its configuration, HTTP requests, index files, connections, CGI, and extras such as custom error pages.

The Common Core DevOps project I enjoyed the most: Docker containers that each run one service (WordPress, MariaDB, Nginx…) and talk to each other.

As a bonus, Grafana / Prometheus monitoring, with exporters hand-written in Go for each service.

A command-line tool that creates web stacks and applications in a single command, from a static configuration: it clones the chosen stacks and sets them up.

Started as a way to learn Go.

A raycaster that renders a parsed map in “fake” 3D. We added a minimap, an animated sprite, mouse support, interactive doors and proper collision handling.

A module of the C++ piscine, which I enjoyed for its mathematical side, especially the Ford-Johnson algorithm.

I added a visualiser to analyse the results and play with the program’s parameters.

A role-playing game inside Discord, with a full-stack web application. My first real large-scale project: it taught me to develop, test and deploy web applications on my own.

Its original universe is built with volunteers and a whole bunch of people who believe in the project.

The last project of 42’s Common Core. Ours is a web adaptation of the board game Onitama: AI, matchmaking, profiles, friends, chat, 2FA and GDPR-related features, in a universe of our own.

A real test of teamwork, where coordination and communication were key. I worked on parts of the back-end and the DevOps.

A Discord bot that adds services such as levels, welcome messages or a support ticket system. Mostly the answer to a need I had for my own communities.

A Discord bot with a game set in the Demon Slayer universe: my first real community project, and my first steps in server-side JavaScript.

I stopped it to free up time in high school, but I enjoyed it so much that I have kept building this kind of project ever since.
