István Ujj-Mészáros

Hi, I’m István Ujj-Mészáros, a Senior Full-Stack Developer with 15+ years of building scalable, high-performance systems. I’m passionate about profiling-first development and enjoy solving bottlenecks in backend architectures and CMS platforms, often leading end-to-end builds for U.S. clients across time zones.

I’ve shipped production frameworks from scratch, crafted headless CMSs with visual builders, and designed modular, enterprise-grade architectures. I’m focused on mentorship, scale-up opportunities, and hands-on problem solving with modern stacks (PHP, Ruby on Rails, Node.js, React/Vue, Redis, Docker, CI/CD). I’m open to remote/hybrid roles and excited to contribute to teams that value robust design and performance.
