Hardware engineer trained in electrical engineering, with two years and five months across two production studios delivering systems into the field — deadline-fixed public deployments for government agencies, a national museum, and major retail, where the equipment had to run on opening day with no second attempt. Owned installed systems end to end: mechanical and electrical installation, commissioning, scheduled preventive maintenance, on-site fault diagnosis and downtime recovery, remote monitoring, and direct accountability to the customer through handover and the warranty period. Strongest at the physical-signal layer — isolating noise, grounding, EMI, and bus or communication faults with instruments rather than by swapping parts. Available for shift work including nights, on-call rotation, cleanroom PPE, and travel and relocation within Taiwan.

• Preventive & corrective maintenance. Owned permanently installed electromechanical systems after handover — scheduled PM cycles, on-site fault diagnosis, downtime recovery, and remote monitoring and diagnostics over the network. Sole engineer accountable through the warranty period.
• Fault isolation at the physical layer. Diagnosed noise coupling, grounding problems, EMI, and bus / communication conflicts using oscilloscope, multimeter, and logic analysis — separating mechanical, electrical, and firmware root causes instead of swapping parts. Traced interference paths on custom hardware and closed them out through grounding and EMI isolation.
• Production support & quality. Resolved technical issues arising in production, ran product verification with the manufacturing team, and took part in quality control.
• Documentation & specifications. Wrote technical documentation and design specifications, compiled test reports, and maintained schematics and design drawings as the controlled reference for build and service.
• Installation & commissioning. Installed and commissioned systems on customer sites against fixed opening dates: mechanical assembly and alignment, wiring, sensor mounting and calibration, and acceptance testing with the customer present.
• Motion control & tuning. Owned a 20 m single axis carrying a 500 kg moving load from drive sizing through on-site commissioning. Effective inertia changes along the travel, so closed-loop position and velocity run over an inner torque loop — one set of gains holding end to end, without overshoot, oscillation, or settling error at the end positions. Separately, converted a manually operated overhead crane carrying a 60 kg armature into a fully automatic system.
• Actuation & timing. Integrated solenoid valves and pneumatic actuators with embedded control, and synchronized mechanical motion with display and audio subsystems on a shared timing reference through continuous daily operation.
• Customer interface. Direct point of contact for government agencies, a national museum, and retail clients — scheduling site access, reporting equipment status, and coordinating fixes while the venue stayed open to the public.
• Electronics build & rework. Custom PCB schematic and layout, circuit simulation and analysis, component selection and BOM management, hand-etched boards, analog assembly, soldering and rework, wiring and power distribution, sensor-to-controller signal conditioning. Design iterations targeted lower cost and power draw and higher reliability.

• End-to-end technical delivery. Led technical delivery of experiential technology projects across exhibitions, corporate showrooms, and trade shows — scope definition, schedule, on-site installation, and client acceptance.
• Cross-functional coordination. Coordinated mechanical, electrical, AV, and software scopes with internal teams and outside contractors against fixed, non-movable show-open dates.
• Technical risk ownership. Assessed technical risk during build and resolved integration and equipment failures on site while the show was running.
• Delivery process. Short iterative cycles on a Scrum-style backlog with task and issue tracking in Odoo.
