Staff engineer, frontend systems, builder/tinkerer.

I help products go from 0 → 1 to 1 → 100.

I specialise in frontend systems and product engineering — taking ideas from sketch to reliable, scalable experiences. I've built both developer-facing products (SDKs, tools, and platforms) and B2B SaaS platforms with customer-facing interfaces used by thousands of teams. I care about the whole journey: discovery, first ship, and the unglamorous scaling work that comes after.

I build products and side projects to learn and grow.

Beyond the Code

Outside of work, I enjoy experimenting with side projects, writing about engineering, and speaking at meetups. I like taking things I’ve learned in real projects and turning them into talks, blog posts, or tools that others can pick up quickly.

You’ll often find me tinkering with new frameworks, improving my dev environment, or helping friends and peers debug their apps and workflows.

Interested in working together?

If you’re building developer tools, SaaS products, or customer‑facing web experiences and need someone who can own both the frontend and the delivery pipeline, I’d love to chat.
