Full-Stack WEB3 Developer
I am Mathis, a freelance web3 full-stack developer from the southeast of France.
👋🌐🇫🇷
2 masters, 2 licences in IT Architecture (Data & Network) from 42 Paris—top of my class. Projects across diverse industries.
💻🎓👔
I've been into Web3 for several years; for the past year I've been developing dApps—EVM and more
recently Solana. I'm also interested in agorism, libertarianism, and anarcho-capitalism.
📜🌕⛏️
I am passionate about web development, algorithms, consensus, and design. As a curious self-learner, I
constantly explore new technologies and strive to perfect my skills.
👨💻🎨📚
AI enthusiast, particularly of LLMs. 🧠
Svelte evangelist, TypeScript adept, and Go worshiper.
I love uncovering the essence of things, recognizing patterns, and architecturing them into elegant systems that automate processes and handle worst-case scenarios.
