What I'm looking for

I'm looking to build and modernize scalable e-commerce or enterprise platforms, combining hands-on architecture and engineering with AI-enabled automation, reliable delivery, and technical leadership.

I've led engineering and architecture at Muztorg.ru, scaling an e-commerce platform serving 1.5M monthly active users and 200,000+ SKUs. I reduced time-to-market by 40%, increased releases from weekly to every other day, and introduced AI automation across up to 45% of operational processes.

Over 20+ years, I've built e-commerce platforms, enterprise integrations, high-traffic APIs, data workflows, and web products using Python, PHP, React, SQL, and microservices. I stay hands-on from requirements and system design through delivery and production while leading distributed teams of up to 25 engineers.
