Summary
👤
SeniorZoltan Feher is a Staff Software Engineer in Budapest with 14 years of experience evolving from Flash and PHP developer to a backend and architecture specialist focused on Node.js, serverless patterns and microservices. He designs scalable, 12-factor applications, breaks down monoliths into maintainable services, and advises on technical debt remediation and cloud cost optimization. At Kasa Living he’s driven developer experience improvements like automated npm releases and preview deployments while optimizing AWS and GitHub CI workflows. Comfortable across the full stack, he pairs hands-on development with pragmatic architecture decisions informed by a background in Symfony, Debian/Ubuntu server ops and early Flash/3D game work. Less obvious: he blends product-aware engineering with developer tooling enhancements that speed delivery while reducing long-term maintenance burden.
