04About

I'm a Full Stack Developer and React Native specialist. I create modern, scalable and user-friendly applications that solve real business problems — web platforms, mobile applications, CRM systems and custom automation solutions.

My focus is frontend architecture, system thinking and product-oriented development: pixel-perfect UI, responsive design and cross-browser compatibility. I've built complex UI systems, real-time applications and AI-powered interfaces, working closely with business stakeholders and product teams to translate requirements into maintainable technical solutions.

I have also developed Python-based Telegram automation tools for user registration and workflow optimization, and I actively use AI development tools (Cursor, GitHub Copilot, Claude, ChatGPT) to accelerate delivery, improve code quality and support architectural decisions.

What I focus on

  • 01Frontend architecture & state management design
  • 02Performance optimization & production readiness
  • 03Real-time interfaces (REST, GraphQL, WebSocket)
  • 04Close collaboration with design (Figma) and product teams
