I've been a web developer since the '90s. I architected, built, and delivered major brand websites like Coca-Cola and McDonald's, but I've also been a core developer at Stack Overflow for 4 years, where I built the help center and a myriad other features. I've been working in many other fields: antivirus, fintech, blockchain... I am a regular speaker at conferences worldwide: Europe, Asia, America. I contribute to open source.
