Singapore · Graduating Apr 2027 · Open to full-time roles

I make automation easier to recover, verify, and trust.

I am a Mechatronics Systems undergraduate working where equipment, controls, operations, and software meet. I turn unfamiliar production systems into repeatable recovery steps, defensible test evidence, and tools people can act on.

Experience that moves systems into production

My work combines first-response equipment support with structured verification, vendor coordination, documentation, and data automation.

Recover and maintain

Worked with automation technicians and vendors to diagnose alarms, clear jams, perform critical checks, and recover AMR, ASRS, AMHS, OHT/OHV, stocker, strapping, packing, and handler equipment. Supported system/server recovery, software roll-outs, and OS/antivirus patching with engineers. Used a multimeter and hand tools to replace and realign a worn stopper within a 30-minute window.

Fleet Manager · e-WareNavi · MCS · GT SoftGOT2000

Validate and launch

Designed and executed more than 50 OHV UAT cases plus stocker, feeder-table, and Lights Out 2.0 integration and exception tests. Prepared FMEA evidence, reproduced faults, and retested vendor fixes before go-live. Feeder automation replaced manual Traystack loading.

UAT · FMEA · exception testing · vendor coordination

Automate and analyse

Built seven live Tableau OHV views for alarms and uptime against a 99% target, a feedback-driven Python issue tracker, and an Excel/PowerShell restock workflow with Outlook alerts covering 36 Priority 1 items. Used RCA and supplier follow-up to reduce digital packing line barcode misalignment.

Hand over safely

Created three controlled 12-hour OJTIs from scratch for OHV, stocker, and feeder equipment, supported operator training, and tracked technician certification and refresher requirements.

Performed Rockwell HRA/HRC and Vickers case-depth testing, metallographic sample preparation, and Cpk, t-test, and variance analysis; confirmed specifications with no process changes required.

May 2021 - May 2023

Signals, Singapore Army

Completed full-time National Service in a Signals unit, building discipline, operational readiness, and team coordination.

Mar 2021 - May 2021

Digital Ambassador, IMDA

Helped members of the public adopt digital services and understand safe, confident use of everyday technology.

AMHS Fleet Simulator

A discrete-event model of a semiconductor-fab OHT loop that tests where adding vehicles stops helping. Throughput stayed effectively flat from 6 to 21 vehicles; cycle time reached 123.1 seconds at 13 vehicles, then rose 34.1% by 21 as blocked fleet-time increased.

Inverted Pendulum Control Lab

A cart-pole simulator that benchmarks cascaded PID, LQR, MPC, and an energy-shaping swing-up controller on the same plant, actuator limit, and cost function. The equations of motion, both Riccati solvers, and the constrained MPC solver are written from scratch in NumPy. Across 169 mismatched plants, LQR and MPC held 84.6% against 55.6% for PID.
