• Applied Domain-Driven Design (DDD) to develop a Warehouse Management System (WMS) tailored for a Just-in-Sequence (JIS) warehouse. This system supported immediate delivery of parts to the production line and managed the return of defective components.
• Implemented real-time tracking for each part during delivery and return, ensuring accuracy and traceability throughout the workflow.
• Developed monitoring functionality to validate the return process. Detected and resolved mismatches between items reported by material runners and items actually received by the warehouse, improving reliability of return operations.
• Designed and built a feature allowing JIS warehouse users to generate parts request lists. Integrated inventory control into the WMS to streamline replenishment from the main warehouse.
• Adopted Trunk-Based Development practices to streamline collaboration, reduce integration conflicts, and support continuous delivery of the WMS.
• Established a high-availability cluster to improve service reliability and minimize downtime in production.

PEGATRON | 2022-2024

• Designed and implemented a comprehensive Pick, Pack, and Ship system. This involved early-stage system design, front-end and back-end development, and integration with various hardware devices to ensure seamless operations.
• Gradually introduced unit tests to a legacy spring framework that previously lacked test coverage. Successfully added over 1,000 unit tests, significantly improving code reliability and maintainability.
• Improved the front-end development workflow by streamlining processes and successfully upgrading the system from Vue 2 to Vue 3, enhancing performance and maintainability.
• Advocated for a strong design phase with clear documentation and user communication to ensure solutions meet needs and deliver value. Practiced these principles in my work to lead by example.
