Programmer and IT specialist in support of tape manufacturing.- Expanded and maintained all the code for our statistical process control system. - Designed database tables - Wrote scripts in SAS, R, BASH and JAVA to keep tables populated with current summary data - Maintained Statit e-QC macros which provided the web reporting front end and email alerts for our SPC system. - Migrated all the back end support scripts from SAS to R. - Lead an education effort to migrate our engineering staff away from using SAS and demonstrated how to duplicate processes in R. (Resulted in savings of over 25,000 in yearly SAS licensing fees.) - Created Lotus Notes document database which served as a repository of tips and tricks as we expanded our knowledge in the open source R Statistical Programming language.- Maintained and enhanced small departmental web server (Yield reporting system written in Java on tomcat) - Rewrote SQL to filter out non-prime parts.- Designed data retrieval processes for collecting MFG data from multiple outside vendors- Maintained parametric data acquisition from manufacturing lines locally and abroad. - Created a number of scripts in BASH to monitor data transfers and send out alerts in the event of database outages.- Created a visual wafer tool using Statit, java-script and HTML to monitor wafer yield. Images of low yield wafers could then be rendered into a web graphic. It was an attempt to find patterns which might hint to trending problems early on with the wafer manufacturing.- Maintained CSP status reporting system
