Summary
👤
Senior🎓
Top SchoolRaymond Buhr is a technical lead in machine learning with 11 years of experience building production ML systems that improve conversion, reduce fraud, forecast financials, and personalize customer experiences. He combines strong Python engineering with cloud-native tooling—SageMaker, Databricks, Kubernetes, Airflow—and deep experience across data platforms from DynamoDB to Snowflake and BigQuery. Pragmatic about automation, he prefers reliable, auditable processes over noisy fully automated systems and champions reproducible experiments through disciplined coding and data infrastructure. He’s led modern data stack migrations and applied models to real business outcomes at companies like StockX and PayPal, and he enjoys mentoring, pair programming, and hands-on tinkering—sometimes building complex machines out of LEGO. His open-source UI work on Jupyter themes reflects an eye for user experience as well as backend rigor.
