I build open-source hardware powered by Bitcoin Lightning to make payments tangible, playful, and real. Bilingual (FR/EN) step-by-step tutorials so any maker or educator can reproduce them independently.

Deployed at 8 international Bitcoin conferences across 5 countries. ~1,474 Lightning transactions processed with ~635 participants. Case studies available at ezmo.dev.

Contributed to BTCPay Server (BitcoinSwitch plugin testing), LNbits (production feedback), and Plan ₿ Academy (first bilingual Lightning hardware tutorial on the platform).
