About

Category manager who builds software around retail data, e-commerce operations and self-hosted infrastructure. I turn recurring operational work into data pipelines, internal tools, OpenCart extensions, deployment stacks and focused utilities.

  • Retail data - Analysis Services and OLAP, BigQuery, PostgreSQL, Excel, Power Query, DAX and ETL pipelines.
  • E-commerce - OpenCart search, catalog and inventory tooling, product feeds, delivery integrations and operational automation.
  • Development - Python, TypeScript, PHP and C++, with AI-assisted workflows for repeatable engineering tasks.
  • Infrastructure - Proxmox, LXC, Docker, Coolify, Linux, Nginx and observability for self-hosted services.

Based in Kyiv, Ukraine.
