About me.

Fullstack engineer combining backend architecture with modern frontend to deliver production-grade solutions.

Backend Software Engineer with deep expertise in Java Spring Boot and modern web architectures. I build scalable, well-architected systems that solve real business problems. Currently an IT student in Prague with a gold medal in mathematics from Ukraine, I'm passionate about clean code, system design, and leveraging AI as a force multiplier for engineering velocity. Fluent in English, Czech, Russian, and Ukrainian.

Technical Philosophy: I orchestrate AI agents to build software efficiently—using Claude Code, GitHub Copilot, and ChatGPT as daily development partners. My workflow is "AI-First," enabling me to focus on architecture and complex logic while accelerating implementation.
