I build software for the web, end to end: from pixel-perfect interfaces and canvas editors to CI/CD, data pipelines and the architecture that holds them together. I've been an early engineer at several startups, led teams, and mentored dozens of engineers along the way. What I care about most is making hard things simple.
This is my lab: things I've built and what they taught me, from charts to home automation to working with AI agents. Each entry has one idea at its core, and figures you can poke at.

The button that does nothing

Who draws the chart?
Build a bar chart, a line, a donut and an axis with React and d3. d3 does the math, React owns the markup, and you animate numbers rather than shapes.
