How I got here

I started in 2019 at TorqueVision Labs, building a risk-monitoring app in Plotly Dash while the framework was new. In 2021 I joined Plotly as a software engineer and worked on dash-DAQ, dash-VTK and the enterprise products. At UsefulBI I built oncology analytics for life-sciences teams and shipped apps on Dash Enterprise. At Lam Research I built process-monitoring analytics for semiconductor manufacturing. In 2025 I co-founded Dextar, where I’m CTO.

Work together

If your team has data that people can’t read yet, tell me what it is and who needs to see it. I build the dashboard, chart or graph view, and hand it over.
