Rockstar🎓
Top SchoolJáchym Toušek is a seasoned backend engineer with 15 years of experience, now focused on Go and Google Cloud after a long career in PHP. He has led backend teams and projects—from rebuilding complex HOA management software to improving developer stacks at Ubiquiti and Spaceflow—often reducing code size through careful refactoring. Jáchym is an active open-source contributor to prominent PHP projects (Symfony, PHPStan, Psalm, Codeception, Nette), where he’s fixed subtle bugs, improved type and static-analysis support, and enhanced core form/validator tooling. At Spaceflow he introduced strict static analysis, optimized CI and rewrote Docker images, showing a pragmatic blend of tooling, quality and delivery improvements. Currently at Keboola he brings that same emphasis on maintainability and cloud-native practices to Go systems on GCP. Colleagues describe him as a pragmatic problem-solver who thrives on untangling tricky domain logic and improving developer experience.
