// who_am_i()Not Your Average Developer
I'm a software engineer from Madrid, Spain who fell in love with code in 2005 and never looked back. When crypto came along, I knew I'd found my calling. Now I architect systems that move millions, build trading bots that never sleep, and help shape the decentralized future.
Web3 Native
Living and breathing decentralized tech since before it was cool.
Full Stack
From smart contracts to cloud infrastructure, I build it all.
Security First
Building robust systems that handle millions in transactions.
Performance
Optimizing for speed because every millisecond counts in trading.
"I've written code for banks, electric vehicles, DeFi protocols, and everything in between. But nothing beats the thrill of deploying to mainnet and watching real value flow through your smart contracts."
