Senior full-stack developer: I build and run web products.
From late 2021 I developed and ran a Hungarian real estate listing platform that I built from scratch. Since 2025 I have built my own SaaS products, EU-hosted infrastructure and AI integrations, and since 2026 Claude Code has been part of my daily workflow. 30+ completed projects, 50,000+ monthly visitors.
