I'm a Senior Software Engineer with 9+ years of experience building large-scale distributed systems and developer tools. I'm currently at Databricks, working on managed ETL orchestration systems. Previously, I built software tools and cloud infrastructure for Harvard's CS50, serving over 1M students and hundreds of teachers worldwide.
