Industrial Projects
Delivered machines & systems end-to-end.
My engineering journey began on the factory floor, programming CNC machines and designing molds — learning that great engineering is measured in microns, repeatability, and the discipline to make ideas manufacturable.
That foundation grew into a decade spanning mechanical design, special-purpose machine development, and automation. I have designed rotary dryers, conveyors, palletizers, and dust collectors, then advanced into robot-integrated systems and battery-line automation.
At NTUST in Taiwan, I earned my M.Sc. in Mechanical Engineering and led research on magnesium matrix composites — combining stir casting, SEM/EDX and XRD characterization, and rigorous statistical analysis to push the limits of energy absorption in lightweight materials.
Today, as a Process Quality Engineer at CATL Karawang, I apply root-cause analysis, continuous improvement, and manufacturing excellence to one of the most demanding production environments in the world. I am driven by a single goal: engineering products and processes that are smarter, lighter, and provably better.

From CNC programming and mold design to special-purpose machines, materials research, and battery-line quality engineering.
Driving manufacturing excellence on a world-leading battery production line through data-driven quality engineering.
Designed special-purpose machines and robot-integrated automation systems from requirement to commissioning.
Led research on magnesium matrix composites, blending experimental mechanics with statistical optimization.
Designed industrial agricultural machinery and material-handling systems for production-scale deployment.
Engineered precision injection molds, translating product geometry into manufacturable tooling.
Programmed multi-axis CNC machining for tight-tolerance components and tooling.
A selection of projects spanning advanced materials research, industrial automation, and heavy mechanical design.
Lightweight magnesium alloys offer excellent strength-to-weight ratios but suffer from poor energy absorption, limiting their use in crash- and impact-critical structures.
Developed a hybrid magnesium matrix composite using an infiltrated stir casting technique that disperses reinforcement uniformly while preserving the lightweight matrix.
Designed a Taguchi-based experimental matrix, fabricated specimens via infiltrated stir casting, and characterized microstructure with SEM/EDX and XRD before validating performance through mechanical testing and ANOVA.
Demonstrated a measurable enhancement in energy absorption — a novel route published in a peer-reviewed journal and a contribution to lightweight structural materials.
High-throughput battery lines require fast, reliable leak detection without slowing the production tact or risking product integrity.
Engineered a special-purpose leakage detection machine integrating pneumatic actuation and robotic handling for automated, repeatable inspection.
Full mechanical design in CAD, pneumatic circuit design and sizing, robot integration for part transfer, and sensor-based detection logic — validated against production tact requirements.
Delivered an automated inspection station that improves detection consistency and removes manual handling from a safety-critical step.
Agricultural processing plants need robust, continuous-duty machinery that handles abrasive bulk material reliably at industrial scale.
Designed a portfolio of production machinery — rotary dryers, conveyors, palletizers, and dust collectors — engineered for durability and serviceability.
Requirement capture, structural and mechanism design in CAD, component selection and sizing, and design-for-manufacture coordination with the fabrication floor.
Multiple machines delivered into active industrial use, supporting reliable, continuous bulk-material processing.
A novel infiltrated stir casting route for fabricating hybrid magnesium matrix composites, characterized across microstructure and mechanical performance, demonstrating enhanced energy absorption for lightweight structural applications.
