I take on complex web systems that need more than code: architectural thinking, clear business logic, integrations, and stable production operation. I’m strongest in projects where I need to understand the business process, design a clear system, and ship it so it works in everyday reality.

I'm a full-stack software engineer with 7 years of experience taking products from idea to production — architecture, business logic, frontend, backend, and the infrastructure they run on. I've shipped booking platforms, SaaS, e-commerce, and back-office systems, and led a team as CTO. The systems I've built have reached over 100,000 people — from a national platform that drew 10,000 users in its first week to a testing platform that ran across 50+ centers.
I care not just about getting a system live, but about getting deep into its details: business logic, architecture, integrations, role-based access, performance, and stability under real load. Clients consistently highlight my clear communication, accountability, and ability to deliver on time.
