Ondřej is definitely a pro in the field: he has 14+ years of experience under his belt and still never stops craving new skills and professional challenges. His journey started with creating computer programs when he was a teenager, and after some time, his hobby transformed into something more serious. He used to work with PHP and then decided to reorient to using JavaScript/TypeScript-based stack. In 2018 blockchain industry really caught Ondřej's attention, and since then, that has become his main focus. He has a comprehensive knowledge of Solidity, knows how to debug his code, and uses best practices in the development routine. Apart from that, Ondřej acquired some commercial experience with Rust and would like to dig deeper into the technology.
