Perform UT Level II inspections on ASME Section VIII vessels, API 650 tanks, and process piping during turnarounds at 4 Corpus Christi-area refineries and chemical plants. Calibrate and operate Olympus EPOCH 650 / OmniScan MX2 for shear-wave weld inspection and corrosion mapping; average 35–45 weld joints and 120 thickness readings per shift. Write indication reports that cut client re-scan requests 28% YoY; zero missed critical discontinuities on third-party audit samples (2023–2025). Mentor 3 Level I technicians on probe coupling, DAC curves, and ASME acceptance criteria; reduce first-time reject rate on training coupons from 18% to 6%.

Conducted ultrasonic thickness gauging and magnetic particle inspection on structural steel and pressure piping for fabrication shops serving offshore and midstream clients. Supported 12+ planned outages; logged 2,400+ UT scans with digital data packs delivered same shift. Collaborated with welding engineers to map repair zones after UT findings, shortening repair loop time by ~1 day on average.

Assisted Level II inspectors with surface prep, probe setup, and data logging for UT and PT on shop fabrications. Completed ASNT SNT-TC-1A Level I UT training and logged required OJT hours toward Level II certification. Maintained calibration logs and couplant inventory for a 6-person NDT crew.

Host volunteer weld-coupon practice nights for Del Mar College NDT students (2022–Present), coaching probe selection, calibration, and indication sizing.

Presented common UT pitfalls on thin-wall piping to regional ASNT chapter members, 2024.
