Rockstar🎓
Top SchoolCatherine Devlin is a senior research associate and back-end developer with 18 years of experience designing and maintaining database-centered systems, excelling at the intersection of Python with Oracle and PostgreSQL. She builds end-to-end data lifecycles—schema and admin, ETL, stored procedures, and web apps—and has applied those skills across enterprises from Disney Streaming to Corning. An active open-source contributor, she has improved widely used Python tools like flask-restful and cmd2 and enhanced SQL tooling in projects such as ipython-sql and pgcli. Her background spans production ETL at scale (Spark/Databricks and Snowflake) as well as hands-on database engineering and CLI tooling, giving her uncommon fluency from low-level query issues to user-facing developer tools. Based in Ohio and trained as a chemical engineer at MIT, she brings a pragmatic, data-first mindset and a knack for quietly improving developer ergonomics and reliability.
