At Charles River Laboratories, I provided field technical support for Endosafe and Celsis rapid microbiology platforms, including troubleshooting, service coordination, and customer training. I also built and used a web app prototype to manage customer data and service records.

At Cytiva, I provided after-sales support for ÄKTA Process, ÄKTA Pure, and ÄKTA Avant chromatography systems. I diagnosed hardware, fluid-path, electrical, sensor, and UNICORN-related issues, and applied LLM/RAG-based knowledge bases to technical manuals and service workflows.

At Wuxi Fuent Biotechnology Co., Ltd., I optimized recombinant E. coli BL21(DE3) fermentation and supported protein expression, harvest, and purification process development. This work improved target protein yield by approximately 33%.

Earlier, at Guangzhou Jinbaili Cosmetics Co., Ltd., I performed microbiological, physicochemical, and production-environment testing and prepared quality records and ISO9001-related documentation. My experience also includes customer URS response, technical documentation, and work in GMP/GLP/GDP environments.
