Gonçalo Sá

Security Engineer

Gonçalo is a passionate hacker since he can remember. Disassembling stuff was always his business, either online or at home. He founded 3 different startups (AdTech, BioTech, Mobile App) but when he realized his real love was decentralization, he turned to Ethereum and never looked back. Since then he has become an unapologetic technocrat that really believes in humanity with a little help from smart contracts. Whenever he’s able, you’ll find him writing or exploiting solidity code, climbing or playing paddle.
