Vernissage | A VR Game
This is a game made for the 2017 JavaScript 13,000 challenge. It uses WebVR to deliver an immersive experience.

The challenge allows the participants to use only 13,000 lines of code (aside from the frame). I had to make some interesting optimizations.

Travel Blog
I wrote a travel blog for a friend of mine. Everything is hosted on GitHub. When a blog is committed a new version is built on Travis and deployed on GH pages.

I tried to keep the app as fast as possible while delivering a simple-but-clean UI. Every thing works offline as I followed progressive app best practices

The Marvellous Surfers
A game that we made with three friends during 48 hours for the global game jam 2017 event. It's a multi-player race that's playable on your smartphone with a fun and catchy ambiance.

This was made with Three.js,, and Heroku.


A website that gives exposure to top-level opticians. their work, and favorite products. A desktop and mobile web app with server-side rendering. Based on React.js, Next.js, GraphQL, and the App Engine.

Sales Buddy
A sales assistant solution that we made for a hackathon sponsored by Microsoft. The solution is composed of two parts:
- A chatbot which provides advice to the customer in the shop and gathers their feedback while doing so.
- A dashboard for the salespeople inside the shop which aggregates meaningful user data which converses with the bot in real time.

Sadly, we came close to winning.
