👋 Hi, I’m Harry

— I am co-chair of performance.now()—the conference for web performance professionals

I am a Consultant Web Performance Engineer from the UK. I help some of the world’s largest and most respected organisations find and fix their site-speed issues.

🚦 Availability

I’m currently booking clients for Q4 2025 and beyond.

Get in touch if speed matters to your business.

🛠️ Open Source

I don’t write as much code as I used to, but my biggest or most recent contributions are:

  • 🩺 Obs.js: context-aware web performance for everyone.
  • 🧼 defaults.css: a thoroughly modern, light-touch reset for people who like writing CSS.
  • 🧠 ct.css: Let’s take a look inside your <head>.
  • 🧊 inuitcss: an extensible, scalable, Sass-based, OOCSS framework for large and long-lasting UI projects.
