Message

At The Marlin Alliance, Inc., I architected a responsive document management UI with React and TypeScript that helped reduce daily processing time by 10% for 300+ DoD end-users.

I also re-engineered legacy SQL and Python scripts into distributed PySpark jobs on Databricks, eliminating out-of-memory errors. Automated Jest and Cypress tests helped reduce production regression defects by 20%.

Previously, as an Application Engineer I at The Vanguard Group, Inc., I supported RESTful and GraphQL APIs and led an AWS infrastructure migration. I also worked as a Software Support Technician at Component Control, installing Oracle databases and maintaining schemas.
