Top SchoolOndřej Hajný is a pragmatic Frontend Web Developer with nine years of experience building production-ready JavaScript/TypeScript single-page apps and embedded GUIs from MVP to launch. Based in Brno, he’s shipped features for large customers like Kiwi.com, developed a tablet GUI for smart-fridge vending hardware, and moves comfortably between freelance projects and product teams. He favors clean, testable code, has hands-on experience with Aurelia, Electron, CI/CD and end-to-end testing, and often mentors colleagues while evangelizing new frontend tools.
