Machine Learning Engineer

• May 2022 - Present

- Developed a complete MLOps framework, infrastructure, tooling, and process for deploy machine learning models to production. This leveraged Azure DataBricks, Azure Data Factory, and Azure DevOps, and included configuring repository management, setting up automated test frameworks, devising & documenting processes, and creating deployment pipelines for both model, feature engineering, & ETL code.- Helped lead the creation of Costco’s data science center of excellence as part of the its leadership team as well as as lead machine learning engineer. This included everything from developing processes & procedures, to designing architecture, to deploying infrastructure, to writing ETL & MLOps pipeline code, to review & approval of all code being deployed to production. - Also served as an individual contributor to various data science projects such as meat sales, gasoline sales analysis, RFM segmentation, supply chain analysis, and more.- currently working with the rest of the leadership to stand up a data science code review board and accompanying standards and procedures- working with multiple data engineers to teach them Delta Live Tables (DLT) so we can start to leverage DLT as our ETL framework and begin to decommission legacy systems and tools, thereby increasing productivity and decreasing TCO. Also contributing to the eventual stand up of a data engineering code review board for this effort.- As part of DLT migration PoC’s, wrote a DLT pipeline that completed the ETL for a report in 10-15 minutes compared to 3.5-5 hours for the original ETL pipeline using Informatica Cloud Tooling- Chair of Data Science subcommittee of the Data Tech Forum, which is a group of Costco IT’s best developers, engineers, architects, and other technical people in data that is changed with making critical technical and technology decisions for the company- working on PoC of digital twin for critical business operations
