Handcrafted Modern Magic.
Built with precision,
powered by imagination.
Little Background
I’m a developer, a curious mind, and someone who believes that technology should serve both people and purpose . I’ve traveled across countries and cultures, driven by the need to grow, to learn, and to challenge myself. These experiences shaped who I am — open, adaptable, and always eager to improve. My mornings start with coffee — preferably two — and my days are fueled by the drive to build meaningful things. I care deeply about impact, whether it's solving real problems or crafting elegant solutions that make life just a bit easier. I dream big: one day, I’d love to contribute to autonomous vehicles or smart systems that rethink how we move and connect. But I also value smaller, more playful ideas — like creating a geography game that makes learning fun and interactive. I listen, I build, I iterate — and I’m always aiming to go further.
Junior Developper
Biotech Dental Digital
Scionzier
Working on internal software in a regulated medical environment, where small bugs can have big consequences.
Became a Software Engineer
Mar 2020After years of uncertainty and jobs that didn't feel meaningful, I enrolled in a full-time software engineer bootcamp. It was the first time in my life that I studied that hard — not because I had to, but because I *wanted* to understand how things work. I discovered the magic behind games and apps, and never looked back.
Print Spooler Optimization
Mar 2025Diagnosed and fixed slowdowns and crashes caused by simultaneous printing. Implemented a queue system, delay mechanisms, and improved logging to stabilize and trace the process.
Secure Batch Selection
May 2025Complete overhaul of a critical form used hundreds of times per day. The previous version allowed human errors when entering batch numbers, leading to production issues and manual corrections.
Backpacker Survival in Australia
Jan 2016Embarked on a solo backpacking journey across Australia, navigating remote terrains, adapting to diverse climates, and managing limited resources. This experience honed my resilience, adaptability, and problem-solving skills in unfamiliar environments.
Invisible but Powerful System Optimization
Jun 2025Rewrote and optimized a background Python script responsible for scanning and moving XML/STL files. The original version caused heavy CPU usage and interfered with other processes, including file dumps that took up to 15 minutes to complete. After rewriting the logic to avoid recursive scans and eliminate unnecessary operations, the CPU usage dropped significantly, and the dump script now runs three times faster. No more slowdowns, no more complaints — just clean, efficient performance.
Automated Multilingual Label System
Feb 2025Built an intelligent labeling system for medical devices. Automatically generates translated texts, country-specific logos, article data, and print-ready PDFs. No more manual mistakes or omissions.

Soft Skills (self-assessed)
A personal web app designed to transform long, clunky psychological tests into a smooth, interactive experience. The idea came after I received a massive paper-based test to fill out by hand — slow, repetitive, and error-prone. So I created a better solution. MindTracker lets users complete psychological questionnaires like the Big Five or Self-Compassion Scale in a clean, mobile-friendly UI. It supports multiple languages (FR, EN, JP), displays live progress, and lets users download a clean PDF at the end — all without collecting personal data.

A compact collection of four Three.js tutorials I followed and customized to deepen my understanding of 3D development on the web. Each mini-project explores a different aspect of Three.js: camera control, lighting, interactivity, and shaders. I modified layouts, materials, and animations to experiment with the API and see what I could achieve. This project really helped me grasp the basics of 3D scenes, the render loop, and the creative potential of WebGL.

This simple browser game was built as part of a take-home assignment that helped me land my first developer job at Potluck. You click on randomly appearing dots to score points — the smaller the dot, the higher the reward. The player can change the game speed and pause at any time. The high score is stored locally in the browser. The design was adapted from Potluck’s own website to match their visual identity.

A small side project inspired by the Pokédex, built with React to practice state handling, component design, and dynamic rendering. I focused mainly on styling, experimenting with CSS layouts and visual hierarchy. The result isn’t perfect, but this project was a fun way to explore front-end logic and responsive design without relying on a CSS framework.

This was a small project built in just 5 days during our “New Language Week” at school. I chose to explore C# and Unity to understand how video games are made. You could walk around a 3D map, jump, or "spam-jump" to reach clouds and collect floating gems. It was more of a sandbox prototype than a finished game, but it helped me grasp key Unity concepts. Unfortunately, the project files were lost later.
