Valentin Ostapenko

AI Automation Engineer & Fullstack Developer.
Building AI agents, MCP servers, and LangGraph workflows that actually ship to production.

About

Building for the web since 2006. Working with AI agents and automation since 2024 — shipping RAG systems, MCP integrations, and LangGraph pipelines for real products.

I focus on the boring middle layer: reliable tool use, clean context management, and automations that don't fall apart in production.
