Solution architect and tech lead building AI-powered retail operations and cryptocurrency trading systems.

Ukraine

Message

I designed and built AI-powered retail operations systems, including a custom warehouse management system and automation for restocking, moving goods between warehouses, and discounting. I also built a RAG-powered customer-support agent using MCP, DeepSeek, and Claude API.

At Evendo LTD, I was CTO / Solution Architect / Tech Lead for a portal that aggregates activities, products, and services for trip and event planning. I led architecture and hands-on development of critical modules, implemented distributed systems, and built and led a six-person engineering team.

In my January 2026 project, I worked on algorithmic cryptocurrency trading bots, including market-making and grid-based strategies. I built a unified exchange integration layer that enabled new exchange APIs to be integrated within 24 hours.
