At Lightspeed Commerce, I designed and shipped four custom chart layers for Benchmarks & Trends, its flagship ML peer-benchmarking product. I also built a shared React and TypeScript charting system that brought nine charts together and untangled five legacy charts.

I was the sole frontend owner of admin reporting and led the homepage redesign. I built accessible, internationalized chart components, shipped embedded Insights, and worked on projects including Trendi, which streamed hashtag messages over WebSockets onto a live map.
