Founder & System Architect Radaptor (PHP) Modular Monolith & Service-Ready Modules at Freelance Frontend Developer
Veszprém, Hungary
Summary
👤
SeniorIstván Ujj-mészáros is a founder and system architect with 13+ years of hands-on experience building modular, performance-first web platforms and CMSs. He created Radaptor, an event-driven PHP framework focused on modular monoliths that can graduate into service-ready modules without code rewrites, emphasizing clear boundaries, contracts and deploy flexibility. Equally comfortable in front-end engineering, he has contributed practical UI improvements to popular Bootstrap components and maintains a long-running freelance practice delivering responsive interfaces and high-quality HTML email. His work balances developer experience and production reliability—automatic profiling, Redis caching and content-negotiated endpoints are built in by design. Based in Veszprém, Hungary, he blends entrepreneurial product sensibility with deep technical craft, often optimizing for incremental adoption and minimal frontend coupling. Notably, Radaptor’s approach lets the same codebase serve both server-rendered widgets and API-first frontends, reducing rewrite risk as products scale.
