001 — ABOUT

Systems thinker, infrastructure builder.

UK-based backend and DevOps engineer with 6 years of experience building reproducible infrastructure, CI/CD pipelines, and high-performance systems. I architect solutions that stay standing after the next "must-have feature" ships to production.

My work spans distributed systems, real-time data pipelines, developer experience tooling, and security-focused sandboxing. I believe in deterministic builds, modular architecture, and infrastructure that can be reasoned about.

Currently focused on WebAssembly-powered developer tools and infrastructure automation through QuestHive. When not shipping code, I'm probably debugging a CI pipeline or contributing to open-source projects that solve real problems.

002 — FEATURED PROJECTS

Aileron

Featured

A blazingly fast, keyboard-driven web environment built in Rust with the Servo rendering engine. Features native window tiling, Lua-configurable keybindings, zero-extension ad-blocking via request filtering, and an integrated AI MCP server that allows LLMs to observe and interact with web content. Designed to be a performant alternative to Electron-based browsers.

Rust · Servo · Lua

Clawdius

Featured

Remote agentic coding environment with WASM-based sandbox isolation. Uses Linux bubblewrap for read-only system access with full filesystem isolation, enabling safe execution of untrusted code while maintaining performance advantages over traditional containerized approaches.

Rust · WASM · Bubblewrap

QuestHive

Featured

Structured knowledge engine for infrastructure automation and technical documentation. Built as an early-stage SaaS platform focused on making infrastructure knowledge searchable, interconnected, and actionable.

TypeScript · SolidJS · Cloudflare Workers

SSR Personal Site

Featured

Brutalist-premium personal portfolio built with Leptos 0.8 and Rust WASM, deployed to Cloudflare Pages. Features a real-time world intelligence monitor tracking 19+ data sources including crypto markets, macroeconomic indicators, stock movers, earthquakes, weather, and LLM benchmarks.
