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. Notably, he pairs practical engineering with UX sensibility—designing interfaces in Figma and implementing data layers for both HTTP and sockets—so his work prioritizes both reliability and user experience.
