Founder · Engineer
I've shipped production products from fintech to creator-tooling · for startups and enterprises, from Budapest to San Francisco.
Before founding the studio, I was CTO at a fintech scale-up, built an AI platform for a knowledge-management company, and audited smart contracts alongside a DeFi protocol.
A mentor once told me: 'code running in production is the only code that matters.' Everything else is a demo.
