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 build developer tools such as Zenith and Bracketlint, and work on Hash, a programming language and tooling ecosystem.

• Zenith: a language-agnostic architecture linter for monorepos, built for humans and agents and written in . You declare contracts such as layers, forbidden dependencies and public entry points, and zenith check points at the import, or chain of imports, that breaks one. Read the user guide here!

• Bracketlint: a linter and formatter for Jinja, Nunjucks, Django, Twig and Liquid templates, written in . Install it with npm, Homebrew or a prebuilt binary.

• 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.

• 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 .

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

• teamsearch: a CODEOWNERS-aware code search tool, written in on top of ripgrep's search libraries. Search only the code a team owns, find out who owns a file, or list the files nobody owns.

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

• Zenith: a language-agnostic architecture linter that enforces import boundaries in monorepos
• 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 that finds a team's code, a file's owners and unowned files
• bracketlint: a linter and formatter for Jinja, Nunjucks, Django, Twig and Liquid templates

• Agent-native tooling: designing developer tools, CLIs and linters that agents can drive as well as humans
• Training and inference pipelines: the pipelines that train and serve the models behind agents
• Electronics: circuit design and simulation

• LinkedIn
• Email
