About Me

I am a Software Developer and active Open-Source Contributor, particularly interested in building tools that make developers' work easier. I have created and contributed to several projects actively used by a wide community, which helped me realize how interesting and valuable the process of improving code quality and developer experience can be. Additionally, I have mentored high school and university students in programming, data structures, and algorithms — an experience that deepened my appreciation for clear thinking, knowledge sharing, and patience.
