• Performs extensive field troubleshooting on rotating equipment for Operations and Process Engineering • Performs RCFA and cause mapping related to equipment failure and provided recommendations to address root cause issues and eliminate repeat failures • Monitors health of reciprocating compressors via Windrock and Prognost and makes recommendations based on findings • Monitors health of special purpose condensing steam turbines and other turbomachinery via Bently Nevada System 1 and makes recommendations based on findings • Recommends and implements mechanical seal upgrades for centrifugal pumps and compressors • Calculates and executes pump rerates to keep process units operating efficiently as economics change • Performs “back of the envelope” and “sanity check” calculations to support sudden off-design operating conditions • Serves as lead SME trainer for new hire Basic Operator Trainees for Pumps, Drivers, and Compressors • Increased reliability from 54 months MTBR to 92 months MTBR while shifting from a PM to a PdM philosophy • Served as coordinator for Valero ROTO Corporate Audit and oversaw a score increase from 524 in 2015 to 698 in 2018 • Managed two interns and served as mentor in the Valero Internship Program, one each in Summer of 2018 and 2019 • Developed Long Range Equipment Repair Plan for major equipment to improve turnaround and capital projects planning • Developed machinery monitoring and protection projects in accordance with Valero’s Shell DEP overlay for critical instruments for rotating equipment • Developed and updated Bad Actor focus list that includes RCFA and action plans for increasing reliability • Implemented key rotating equipment health metric calculations into PI ProcessBook, such as polytropic efficiency and theoretical discharge temperature for early detection of potential issues • Developed and implemented Over Speed Test program for general purpose and special purpose steam turbines

• Stewarded the first site lubrication program and decreased lubrication related pump failures from 50% to 10% of total failures • Managed a team of three pump mechanics that served as site lubricators that were responsible for performing daily lubrication- related tasks on a quick response basis • Managed and implemented projects and programs to increase lubrication related reliability such as centralized oil mist systems, operator care IntelaTrac rounds, monthly oil samples and analysis, lubrication PMs and PdMs • Wrote lubrication monthly reports that were distributed plant-wide to communicate lubrication program progress to garner support and increased ownership from the Operations department
