About

PHP developer with nine years of experience, the last six as a main occupation, building and maintaining web applications in Nette and Laravel. Dozens of production applications carried from PHP 5.6 up to 8.5, daily work with MySQL, Git, CI/CD, Docker and Linux.

Clients span healthcare, government, e-commerce and sports, from small e-shops to a shared platform running five hospitals.

Trained as a computer scientist with a focus on embedded systems. A master's thesis on an ARM-based embedded Linux device still shapes how he thinks about performance and real-time data, see Education.

AI agents, mainly Claude Code, are part of the regular workflow, used for code review, refactoring and test writing, a tool for working faster rather than a replacement for judgment.
