About

Senior full-stack partner for booking and conversion-oriented web products.

Who I Am

I help companies turn fragmented booking processes into scalable digital products. My work combines product thinking, clean architecture, and conversion-focused UX. I usually lead delivery end-to-end: discovery, implementation, optimization, and post-launch support.

How I Deliver Value

  • Business-first approach: every technical decision supports revenue or operational efficiency.
  • Fast iteration loops with transparent communication and async collaboration.
  • Production-ready code: performance, SEO, stability, and maintainability by default.
  • Strong domain experience in transport, reservations, and payments.
