About Me

When I’m most useful

  • Greenfield projects from zero to production
  • Complex or forms-heavy frontend systems
  • Legacy codebases that need stabilization

Typical reasons to hire me

  • Architecture is unclear or overgrown
  • Delivery became unpredictable
  • Frontend slows down the whole product

Lead Frontend Developer / Frontend Architect with a focus on building and stabilizing complex frontend systems. From greenfield launches and architectural decisions to refactoring legacy codebases and creating internal tooling that speeds up delivery. I work with React, Next.js, TypeScript, and Node.js ecosystem. Available for Upwork, part-time, consulting, and short-term projects.

How I help projects

I help teams design, launch, stabilize, and scale complex frontend systems — from initial architecture to production-ready delivery. I’m usually brought in when a project needs clear architecture, predictable delivery, or serious refactoring — not just more code.

  • Build frontend systems end-to-end — from zero to production
  • Design scalable frontend architecture
  • Refactor and stabilize legacy codebases
  • Build internal tools and automation
  • Integrate AI-assisted workflows
  • Support teams as a technical leader
