Projects

Here's a selection of projects I've worked on. Hover over them to see the image. Click the highlighted ones to view more details.

Master Calendar

A faster way to look at the calendar

This project was made the speed up the process of looking at which class we have to move to. It is around 50 times faster than the official calendar, used to help students manage their time more effectively.

Perception VLM

Object classification with Vision LLMs for robotics

A team project to classify objects. We used local LLMs with ollama and llamacpp, tested prompts, simulated robot vision and calculated probabilities.
We have also trained a classifier paired with the LLM to get an uncertainty value for identification of any object.

Multi-agent

A multi-agent strategy to collect treasures

The goal was to collect all treasures and put it in a single location, while having asynchronous agents.
Our strategy was to use a centralized agent to manage different stages of the game : exploration, collection, ...
We were able to build a robust strategy to prevent agents from getting stuck, and collecting treasures efficiently.

Connect 4

A game of connect 4 in Unity

This game runs on mobile and has 2 modes: gameplay and simulation
The video you see is the gameplay mode, and you can choose in the menu between 1 player, 2 players or bots fighting.
You can also choose the algorithm and the stength of the algorithm.

AI Robots

A game of robots in Python

A robot project with different strategies. My strategy was to use neural networks.
I ran 40 python scripts in parallel to speed up the process, tested multiple weights, learning rates, and activation functions.

This strategy helped us get 2nd place out of 17 groups in the tournament.

AI Model Modification

Modifying a diffusion model to generate Minecraft-like images

I trained a LoRA with 156 screenshots from the game Minecraft, and used it to modify an AI model output.
The images are carefully prompted for a better dataset.
This LoRA v5 was trained with 512x512 images for 1h on my GPU.

Image Denoiser

Training a model on a custom dataset to denoise images

The denoising algorithm for videos on my phone was lacking, so I decided to train my own denoiser.
Dataset are pairs of images, one with a long exposure time with low noise/iso and another with a short exposure time with high noise/iso.
It's a patch-based denoising autoencoder, and I can change various parameters for better results. This example was trained on around 300 images.

Python GPT

Building and training a GPT model from scratch in Python

I trained a GPT model from scratch using python and the pytorch library for faster training.
The model was trained on a custom clean dataset I made for this purpose of 1.3M characters from chatGPT 3.5, and it was trained for 1h on my GPU.
It only has 3.3M parameters, but it can answer questions with decent accuracy.
Of course, this doesn't compare to the real GPT-3.5, which has around 50000x more parameters, but i'm working to make the dataset bigger to improve the model.

Bluetooth Speaker

A custom made, thin bluetooth speaker

I wanted a thin speaker that could fit in my bag without bulging, so I made my own.
I cut the wood, painted it, bought parts, soldered them, and assembled everything.
The final product is 26mm thick. It has 2 18650 batteries, 4 speakers, a bluetooth module, supports audio from 3.5mm jack and charges via USB-C.

React Website

A fully working website with forums

This project uses React, Node.js, Express and MongoDB.
It has a login system, hundreds of messages, and a user system.
It supports filtering, message posting, editing, account creation, different roles, forum permissions, and more.

Tic Tac Toe

A perfect tic tac toe bot in Python, C and Unity

Have you ever wanted to play against a perfect bot in 3 different languages? Me neither. Have fun!

Clock.

A simple clock optimized for maximum screen efficiency and readability

I made this to have a clock that's readable from far away.
It has some features like a boldness slider and a mode to prevent OLED burn-in. Feel free to try it out by clicking here.
