Belső Dániel
Full Stack Engineer & Infrastructure Builder
12+ years building production systems professionally. Engineering background at LastPass, SzallasGroup, Trendency, and Billingo. Currently building TivadarCMS - EU WordPress for Agencies.
Engineer first.
Consultant second.
I started building websites in 2006. Since 2012 I've worked full-time as a professional engineer across security-critical infrastructure, CMS platforms, billing systems, and high-traffic SaaS products.
My background spans PHP microservices at LastPass, Kubernetes-based CMS at Trendency, billing infrastructure at Billingo, and large-scale SaaS at SzallasGroup. Across these roles I've worked extensively with Symfony, Kubernetes, Docker, ArgoCD, PostgreSQL, Redis, and GitLab CI/CD in production environments.
I build things properly. Not because it's required — because it's the only way worth doing it.
