About

I started programming from pure curiosity about how systems work — inspired by tech culture and the desire to understand what happens beneath the surface.

With no formal education, no courses, and no corporate background, I taught myself everything from open online resources. My journey progressed from experimentation to structured engineering.

Today I build production-grade systems for security research, hardware analysis, and automation. Every project is built with full system control — no black boxes.

  • Understand the system before extending it
  • Reliability over hype
  • Prefer simple architectures that scale
  • Hardware integration: Arduino, ESP32, RF systems
  • Write software that is easy to debug and maintain
  • Languages: Russian | English | German
