> Fullstack engineer in Bucharest with 10+ years shipping web platforms, backends and mobile apps that teams rely on. Top 3% on Toptal, open to new projects.

I’ve been a fullstack engineer my whole career, shipping web platforms, backends and mobile apps. My work spans security at a digital-native bank, fiscal compliance across European markets, retail and real estate apps used at scale, payments, and national-scale systems at Romania’s institute for informatics. Today I build whole products, from database to deployment, and I use AI as a force multiplier inside a process designed so that speed never costs reliability.
