About Me
Full-Stack developer with 2+ years of experience. I write code in JavaScript and TypeScript. Throughout my
career, I have worked on both typical web projects and non-standard ones in the Web3 space. Multiple-time
winner of international programming olympiads, which sharpened my problem-solving skills, algorithmic thinking,
and ability to perform under pressure. I have built complete applications single-handedly as well as collaborated
in teams of up to 10 people. I also frequently took over existing projects - refactoring legacy code, adding new
features, and bringing them to a production-ready state.
