Summary
🤩
Rockstar🎓
Top SchoolTomas Sebestik is a Software Automation and DevOps Engineer based in Brno with five years in IT and a longer career grounding in mechanical and production engineering. He combines a hands-on passion for automation, microcontrollers and embedded systems with practical DevOps work at Espressif, where he contributed type-checking, CI improvements and tooling to the widely used esp-idf IoT framework. Previously he led engineering and robotics efforts at Fritzmeier CABS, moving from mechanical design into management and automation. Tomas favors pragmatic automation—if it can and should be automated, he’ll build the tool—and enjoys creating end-to-end solutions that blend software, electronics and hardware. Colleagues describe him as someone who turns repetitive workflows into reliable, maintainable pipelines and delights in making previously impractical ideas work in the real world.
