PROFILE
Brad Miro
Worked on the GoogleCloudPlatform/devrel-demos repository, delivering end-to-end data science and machine learning workflows focused on cloud-based analytics and deployment. Built and enhanced Jupyter and PySpark notebooks for webinars and customer demos, integrating Apache Spark, BigQuery, and Iceberg to demonstrate purchase prediction and lakehouse architectures. Improved deployment reliability by containerizing workflows with Docker and refining project scaffolding for reproducible demos. Addressed production stability by fixing inference server bugs and implementing observability through Python-based logging. Emphasized maintainability and onboarding by cleaning repository scaffolding, updating configuration defaults, and enhancing documentation, resulting in faster experimentation, improved troubleshooting, and streamlined onboarding for data engineering teams.
