Hardware engineer trained in electrical engineering, with two years and five months taking electromechanical systems into deadline-fixed field deployments — government agencies, a national museum, major retail. Owned those systems end to end: schematic and hand-etched PCB, closed-loop motion control, on-site commissioning, and long-term maintenance of permanent installations. Core work has been PID tuning of position, velocity, and torque loops under varying inertia; multi-axis timing synchronization across mechanical, display, and audio subsystems; and instrument-level isolation of noise, EMI, and communication faults at the physical-signal layer. Equally fluent in software — Python, C++, and PyTorch for sensor data normalization, real-time inference, and vision-based localization. Seeking to bring this cross-layer troubleshooting to precision semiconductor equipment, where control-loop stability, signal integrity, and uptime are the whole job.

• Closed-loop motion control & drive sizing. Specified and tuned a 20 m single axis carrying a 500 kg moving load — a 600 W AZX servo through a 25:1 planetary gearhead sized against the load's torque and inertia budget, driven by an AZXD-SED over EtherCAT with battery-free absolute encoder feedback. Because effective inertia varies along the travel, position and velocity run over an inner torque loop, so a single set of gains holds end to end without overshoot, oscillation, or settling error. A separate bay in the same venue took the opposite approach — PLC logic control for point-to-point positioning — where a manually operated overhead crane was converted to fully automatic operation.
• Multi-axis synchronization. Aligned mechanical motion with display, audio, and lighting subsystems on a shared timing reference, compensating following error and pipeline latency so independently clocked systems held step through continuous daily operation.
• Hardware design & fabrication. Custom PCB schematic and layout, hand-etched boards, analog assembly and rework; coupled physical sensors to embedded controllers, including signal conditioning and normalization of raw sensor data before it entered the control and inference path.
• Field maintenance & uptime. Owned permanently installed systems after handover — scheduled preventive maintenance, on-site fault diagnosis and downtime recovery, remote monitoring and remote diagnostics over the network, and warranty-period support.
• Physical-layer diagnostics. Isolated noise coupling, grounding problems, EMI, and bus / communication conflicts by instrument — separating mechanical, electrical, and firmware root causes instead of swapping parts.
• Delivery process. Ran projects in short iterative cycles on a Scrum-style backlog, with task and issue tracking in Odoo, coordinating mechanical, electrical, and software scopes to fixed on-site deadlines.

• 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.
