Core member of cross-functional team responsible for CNC machine uptime with primary focus on YAG laser systems. Performed machine alignments and calibrations to manufacture specifications. Utilize RSLogix to modify control ladder program fixing sensor calibrations and safety concerns along with troubleshooting. Worked with Allen-Bradley, Fanuc, Wago and Siemens controls. Assist engineers in machine upgrades and integration of new equipment. Use CMMS for daily work order activities. Obtained 6-sigma green belt and was a member on 2 projects.• Troubleshot and repaired laser reliability issue that caused nearly a year of down time and cost the company $800k.• Proposed and implemented upgrades for the computers within the laser controls for the best possible solution that resulted in a 95% cost reduction over OEM vendor.• Liaison between maintenance and IT departments for integration of new equipment and resolving technical problems.• Setup PLC on machines for remote web based status watch and monitoring through a KEPServer.• Integrated new Fiber Laser on existing laser machine increasing throughput of machine and minimizing down time.• Built laser chill water system using Allen-Bradley PLC and HMI to maximize efficiency of system and use less power.

As the key developer and programmer, was responsible for technical aspects of business and managed Linux servers for online software application. Used PHP to program backend and interface with PostgreSQL database.• Developed Daily Meal Planner tool using USDA food database, allowing precise rations of protein, carbohydrates and fats.• Created Body Composition Analysis tool for use with body fat calipers and tape measure that graphed the client’s body fat percentage.• Designed databases in MySQL and PostgreSQL to track all clientele and business data.• Installed and configured RedHat servers running Apache, PHP, MySQL, and PostgreSQL for hosting web application.

Gained valuable hands-on experience supporting five test engineers providing latest test specifications and technical support as needed. System tested excimer lasers to company and customer specification using LabVIEW, automated test equipment, spectrometers, oscilloscopes, power / energy meters and various other tools. Provided technical support for system scientist and senior engineers while building research and development platforms for testing prototype systems.• Automated customer report utilizing VBA and XML parser that reduced compilation time from a manual 8 hours to 3 minutes and allowed management to determine quality of laser.• Created a configuration checker in Excel that eliminated the possibility of shipping or testing a laser with the wrong configuration.• Developed tool in Excel for archiving a daily history of laser status throughout test that was used for cycle time vs. troubleshooting hours.• Worked with IT developing PHP web based collection forms and reports to replace Excel based tools.• Built and troubleshot LabVIEW based Automated Test Equipment that tested laser functionality and performance.
