Hi, I'm Valerii

Backend developer. Architecture nerd. Based in Ukraine. I've spent the last decade building Node.js applications and learning (often the hard way) what makes systems maintainable at scale.

These days I focus on database architecture, API design, and bringing AI into production - agentic systems, RAG pipelines, and helping teams avoid the mistakes I've already made.

What I work with: TypeScript · JavaScript · Node.js · Databases · AWS · GCP · LangChain · Mastra · MCP · Claude API
