I'm a staff engineer at @userledio, based in the UK, where I lead AI initiatives across the product. I'm passionate about infrastructure, developer experience, system design and agentic technologies, and about building tools and systems that make engineering more sustainable, safe and fun. In my spare time, I'm building Hash, a programming language and tooling ecosystem.

• Hash programming language

  • compiler: the core Hash compiler, hashc, written in .
  • spec: the Hash language specification, written in Sphinx and . Read all about it here!
  • metrics: the Hash compiler metrics collection system, written in .

• 🧭 Zenith: an experimental architecture linter for TypeScript and JavaScript monorepos, written in . It enforces rules about which parts of a codebase may import which, such as layers and forbidden dependencies. Work in progress.

• Graphika: a toy graphing library written in pure , as an alternative to Chart.js and other charting libraries.

• Durachok: an online game for playing Durak, a popular Russian card game. Built with + , including some cool libraries: @tanstack/router, @tanstack/react-query, socket.io.

• Bracketlint: a simple HTML/Django template linter that checks brackets are correctly matched, written in .

• teamsearch: a CODEOWNERS-aware code search tool, written in .

I lead developer experience at @userledio, and I build tools on the side to make engineering faster and safer:

• Zenith: an architecture linter that enforces import boundaries in TypeScript and JavaScript monorepos (work in progress)
• prbot: a Slack and Discord bot that reacts to GitHub PR links with emoji showing each PR's live status
• teamsearch: a CODEOWNERS-aware code search tool
• bracketlint: an HTML/Django template linter that checks brackets are correctly matched

• Agentic AI: LLM agents, tool calling, evals and MCP servers (Mastra, Vercel AI SDK)
• Retrieval: embeddings, vector search and RAG pipelines
• Infrastructure as code: Terraform, CI/CD design and cloud-native patterns

• LinkedIn
• Email
