about
Hey there, I'm Kateryna! 👋
Kateryna K.
Full-stack Developer
I'm a Software Engineer who specializes in creating impactful digital experiences. My core stack includes React, TypeScript, and Node.js, which I leverage to build responsive, intuitive applications that deliver exceptional user experiences.
Beyond professional work, I dedicate time to developing meaningful personal projects that solve real-world problems and serve as laboratories for exploring new technologies.
I'm committed to continuous learning, with current interests spanning Web3, Rust, and advancing my expertise in both web and mobile development. I believe in writing code that's not only functional but also maintainable, performant, and architected for long-term success.
