About me

4+ years in backend engineering, at Doubletapp since 2023. I design systems and shape product decisions with clients, balancing reliability, delivery speed, and business value.

Tech Lead experience: led 3 backend developers and 1 ML developer on an AI-agent platform. I mentor engineers and conduct technical interviews.

I develop Agent Skills, custom MCP tools, and agent workflows for task decomposition, dependency planning, context gathering, and development automation.

I treat engineering processes as part of the product: I improve CI pipelines, code review, and development and task-management workflows to make collaboration clearer and delivery more reliable.

Systems I work on

  • High-load backends — APIs, async processing, caching, and production observability.
  • AI platforms — agent orchestration, RAG pipelines, and knowledge bases.
  • Telegram / VK Mini Apps — payments, integrations, and media processing.

Open source & collaboration

My open-source work spans AI and agent-development tools, MCP servers, and Agent Skills, as well as security, API governance, and automation for backend projects. Open to collaboration — let's talk.
