EXPERIENCE

Software Engineer, Chunghwa Precision Test, Taipei, Taiwan Mar. 2021 – Now

Python/Asyncio/Flask/SQL/Redis/Shapely

• Developed and maintained an in-house distributed job scheduler for various design tools. Dozens of tools are running on the system stably and the number keeps increasing.

• Adopted Redis-Queue for user notification and Redis-Lock to avoid race condition when multiple threads or machines working on the same file.

• Implemented timeout mechanism for job scheduler using multi-threading and subprocess to ensure tasks will not be stuck forever.

• Refactored and integrated legacy bespoke modules to simplify the execution flow of worker threads for job scheduler into one flexible class.

• Developed geometric algorithms for mechanical design automation and cascaded Solidworks APIs with remote python auto-design services to build design flow for the next generation in-house mechanical auto-design system.

• Built auto-dimensioning and data extraction modules for an in-house mechanical semi-auto design system, which saved 20% of designing time per case.

Mechanical Engineer, TECO Electric & Machinery, Taipei, Taiwan Nov 2013 - Mar 2020

• Expatriated to TECO-Westinghouse in NA in 2017. Established regional engineering team for functions of

motor quotation and technical service.

• Facilitated cross-functional communication to accelerate a cross-region collaborative project with multiple

teams between NA and Taiwan.

WORKS
