Hi, I'm Alexandr 👋

Full-stack software engineer · Applied AI & Infrastructure
Minsk, Belarus · 6+ years of experience

I build web applications with React, Next.js, Node.js and Ruby on Rails — from architecture to deployment.

I enjoy working with LLMs, RAG and MCP, building useful AI features, and making complex things easier to use.

I also handle servers and DevOps: self-managed infrastructure, Docker deployments, CI/CD pipelines, cloud migrations, and ongoing server maintenance.

Former JavaScript and computer science teacher. Always happy to share what I learn and meet people who love building things.
