Hi there 👋

I'm Andy, a Staff Engineer at Cense with over 16 years of experience building maintainable, accessible, testable, and performant software.

I’ve spent time at companies including Cloudflare, Glassnode, Chess.com, and Orange Logic, working across product engineering, infrastructure, tooling, design systems, CI, performance, and developer experience.

I love experimenting, building, and learning through fast iteration. I’m especially interested in tooling, infrastructure, productivity, AI, and the future of how we build software.

I care deeply about quality and longevity. I prefer simple, durable systems built on strong foundations: use the platform, reduce unnecessary complexity, and make the right thing easy.

What I’m interested in

  • Building useful products and tools
  • Fast iteration and experimentation
  • Developer experience and productivity
  • Web performance and accessibility
  • AI-assisted workflows
  • Infrastructure, platforms, and automation
  • Long-lasting, maintainable software
