Summary
Computer Science student at Taras Shevchenko National University of Kyiv with a solid
engineering foundation and commercial development experience. I specialize in building
comprehensive web applications, designing databases, and automating business
processes. Experienced in end-to-end development: from creating client interfaces and
integrating payment gateways to building secure B2B admin panels and writing algorithmic
bots.
My motivation is not just to write code, but to engineer reliable architectural solutions that

quality, performance, and security.
