Polyvalent developer for over 15 years, based in Haute-Savoie. I combine software development and electronics/hardware - because why choose when you can do everything?

I started with HTML/CSS/PHP, but since then, I've evolved into a complete "maker" profile: from backend code to PCB design, through interface design and entrepreneurship.

I create tools for independents, usually solo, although sometimes I collaborate with my friends (notably lakazatong on some projects).

Pupsbot - My osu! bot that helps players find beatmaps suited to their level. Over 185 commits, used by thousands of players.

My story with osu! started in 2013. I reached global top 3000 in osu!mania, then migrated to the main mode. I created my first bot (Farbot) 4 years ago, but it was technically fragile. In January 2025, I started from scratch to create Pupsbot: stable, fast and modern.

osu! shaped my way of thinking and coding. This project is my way of giving back to a community that has given me so much.

JavaScript/Node.js - This is where I feel most comfortable. I love the flexibility and speed of development. Sometimes it works on the first try, sometimes not.

HTML/CSS - Solid foundations, even if CSS sometimes still makes me grind my teeth. Flexbox and Grid, my friends for life.

PHP - My starting point, still useful for certain projects. Yes, PHP is still alive in 2025, deal with it.

MySQL - SQL queries are like a puzzle I enjoy solving. JOIN, WHERE, and sometimes curses.

TypeScript - I hate this, but it's mandatory to know at least a minimum. Strict typing gives me pimples.

Vue.js - Nice framework, lighter than React in my opinion. At least it's not Angular.

Next.js - For React projects, it's become my default choice. Sometimes overkill, but it works.

C/C++/C# - I rarely do it, except when I tinker with Arduino or other embedded projects. Memory management is not my thing.

Python - Perfect for scripts and automation. Mandatory indentation, but at least it's readable.

Editors: VSCode and Cursor (because AI is the future, but not yet)
OS: Windows 10 LTSC (because stability is important. And yes, I code on Windows)
Testing: Google Chrome and Polypane for responsive (because testing on one browser is for amateurs)
Infrastructure: My own home server with multiple routers - I have perfect mastery of my network (and yes, I have routers everywhere at home)

• ESP32 - BLE, ESP-NOW, I²C, external EEPROM communication (because WiFi isn't complicated enough)
• Arduino - For embedded projects and rapid prototyping (and making LEDs blink)
• Raspberry Pi - Kiosks, monitoring, audio/video interfaces (mini-computers everywhere)
• PCB - Design on EasyEDA, manufacturing via JLCPCB (because breadboard is for beginners)
• Engraving - On glass and PCB for creative and technical aspects (and because it's stylish)

Node.js + MySQL + Redis + Express + Nginx

This combination allows me to create fast APIs and web applications that hold up. Redis for caching (because memory is expensive), MySQL for persistent data (because NoSQL is good, but SQL is better), and Express to properly structure my routes (or at least try).

Node.js + MongoDB + React/Next.js + Redis + GraphQL

I want to switch to MongoDB for more flexibility in data structure (because schemas are constraining), and deepen React/Next.js for the frontend (because Vue.js is good, but React pays better). Redis stays in the equation, it's too practical to give up (and GraphQL because REST is so 2020).

TAI (Technicien d'Assistance Informatique) - French state diploma Bac level, specialized in commissioning and troubleshooting digital equipment (because not everyone can be self-taught).

TSSR (Technicien Supérieur Systèmes et Réseaux) - French state diploma Bac+2 level, focused on maintenance and operation of IT infrastructures (and yes, I studied).

Google FDM SEO Certification - Specialization in search engine optimization (because being visible is important).

CCNA (Cisco Certified Network Associate) - Recognized certification in computer networks (and yes, I know how to configure routers).

CIW JavaScript Specialist - Certification attesting to advanced JavaScript skills (because JavaScript isn't just tinkering).

• osu-utils - Tools to manipulate various aspects of the osu! game in Node.js (because osu! isn't just playing)
• cipherforge - Password generation and testing (because "password123" isn't secure)
• Composa - Complete library for sending emails via xHTML templates (because emails aren't just text)
• SmartyHDD - CLI disk utility with SMART PDF reports and printable labels (because disks can fail)

• LumiRail - ESP32 master/slave system to control LEDs with visual timeline editor (because LEDs are stylish)
• Multimedia kiosks - Raspberry Pi for Spotify, YouTube, local audio (because music is important)
• Custom PCBs - Design on EasyEDA, engraving on glass and PCB (because breadboard is for beginners)
• ESP32 projects - BLE, ESP-NOW, LED drivers, scalable architectures (because WiFi isn't complicated enough)

• Mijote - Participation in the development of an anime/manga-based language SaaS (project in progress, and yes, it's weeb)

Sometimes code compiles on the first try, sometimes not. That's what makes the job interesting. And sometimes, you debug for 3 hours to find that a semicolon was missing.
