Backend and data engineer at Hamilton Medical building validated manufacturing data pipelines and quality-system services.

Message

At Hamilton Medical, I design backend data normalization and validation services for records from quality and enterprise systems. I also built a Rust REST API for bulk quality event submission, with server-side validation before data enters enterprise systems.

I’ve built Python ingestion and ETL pipelines across manufacturing and quality systems, and developed an LLM-based parsing pipeline that reduced manual data entry by six hours per week at ET-Lode. At Mary's Gone Crackers, I led a six-month enterprise system migration and programmed SQL queries and recurring ETL scripts to move business data to AWS S3.
