Developed unified database for several semiconductor device production processes enabling tracking a multitude of different production and experimental runs. Using consumer barcode printers and 2D scanners, created a fully automated process validation and parts tracking system, completely eliminating errors in parts assignment and data entry. As process owner for MOCVD/MOVPE tool, led a team of engineers through a complete teardown and rebuild, resulting in defect reduction of 10x and corresponding increase in process yield. Designed and wrote software to create and manipulate x-ray topography images from raw data; a capability unavailable even to the x-ray tool manufacturer. Developed Excel 2D mapping software enabling faster, easier, and more accurate data- driven decisions. Wrote and developed probe station drivers to reduce testing and data wrangling time by 85%. Using Python/Flask, created a company intranet site allowing real-time charting and report generation. Managed transition from web services provider to Gmail for Business/Google Apps. Managed the operation of multiple process tools while simultaneously incorporating design and process changes in order to continually increase crystal yield and size. As a member of the safety team I developed our lockout/tagout procedures. I assembled and maintained process tools including setting up maintenance schedules, maintaining UHV pumps and equipment, building custom electrical hardware and was responsible for facility build-out for tool installation. I wrote procedures for crystal growth process as well as equipment and maintenance procedures. Seeing the need for a multiple platform process data entry method I initiated, designed and programmed a SQL database and browser based data entry application.
