Hey, I'm Mark 👋
I'm a data scientist and AI engineer working across insurance risk modeling, financial analysis, and AI-driven products. These days I'm at Aon as a Catastrophe Modeling Analyst — modeling risk at scale with Databricks, Snowflake, and ML. Off the clock I build AI side-projects I actually want to exist.
A few fun facts
- 🌎Lived & worked across Brazil, China & the US
- 🐻Berkeley MEng → catastrophe modeling at Aon
- 🛰️Taught a model to spot wildfires from space
- ☕I build stuff
