Available to hire
With over 20 years of experience in web development, I’m passionate about creating and implementing challenging projects. I enjoy learning new technologies but always choose the right tool for the job rather than getting stuck with outdated ones. Recently, I have been exploring Rust and Zig languages for fun. I am enthusiastic about improving developer experience and productivity, often innovating with new tools and architectures.
