Work
A selection of projects from the last three years — design systems, performance work, real-time interfaces, and the occasional open source tool.
Component library and design token system powering 12 products across a Series B fintech company. Built the full stack: primitive tokens, semantic tokens, component tokens, 80+ components, Storybook documentation, Chromatic visual regression, and a migration playbook. Saved 40 engineering hours per week.
High-performance real-time dashboard handling 50,000 price updates per second. Used canvas rendering for the order book and a custom WebSocket reconciliation layer to achieve consistent sub-16ms frame times. Built in Astro with a React island for the interactive chart.
Full Core Web Vitals audit and performance rebuild for a €50M ARR e-commerce business. Identified and fixed LCP, CLS, and INP regressions introduced during a rapid feature sprint. Lighthouse Performance went from 54 to 100. Organic search impressions up 34% over the following quarter.
Headless CMS with a custom block-based editor for a media company publishing 200+ articles per week. Editors get a Google Docs-like writing experience; the frontend gets fully static Astro output with zero JavaScript by default. Preview latency under 200ms.
Open source CLI tool for automated accessibility auditing of production sites. Wraps axe-core with a CI-friendly reporter, Git integration for tracking regressions, and configurable WCAG level targeting. Used by 300+ teams.
IoT sensor visualisation platform for a smart building company. Displays real-time data from 2,000+ sensors across 15 buildings. D3.js charts with WebSocket updates, map-based floor plan overlays, and a configurable alerting system.
