Biography

I am a Software Engineering graduate from Arizona State University with experience across backend development, full-stack applications, and interactive products. My work has included professional backend development at EPAM Systems, full-stack feature development at Toyz Electronics, and independent projects spanning real-time web games, database-backed platforms, strategy games, and ecosystem simulations. I enjoy turning complex product requirements into clear, maintainable systems and improving software through practical iteration, debugging, and testing.
