Maintained and troubleshot high-speed semiconductor handler and AOI systems (Vitrox TR1000i/1100i/3000i, TRS HEXA, CYT H900). Diagnosed and resolved issues involving vacuum systems, servo axes, motors, and fiber-optic sensors to minimize downtime. Executed preventive maintenance and calibration, supported motion control tuning, pick-and-place alignment, and yield inspection processes in a high-volume manufacturing environment. Collaborated with cross-functional teams to improve equipment reliability and production efficiency.

Supervised and trained field technicians in fiber-optic installation, testing, and service delivery. Ensured compliance with SLAs and timely completion of work orders. Conducted quality inspections, monitored team performance, prepared technical and operational reports, and coordinated with project stakeholders to resolve technical and scheduling issues.

Inspected structural and piping works for compliance with classification society and shipbuilding standards. Performed hydrostatic testing, dimensional surveys, and documented inspection results. Prepared quality control reports and supported corrective actions for non-conforming work.
