Skills
In terms of what I use everyday: Python, SQL, dbt, Snowflake, Git, and Looker. I experiment with other tools in personal projects and have used other tools in the past. AI is a big part of how I work — for writing code, exploring ideas, and building things quickly. I like pi, which I used to build and maintain this site.
