Softpower International Information Technology Co., Ltd.

Microsoft Bing • Full-time

Mar 2024 - Present • 2 yrs 2 mos

As an official Microsoft service provider, I led the full-cycle development of the Bing BZA brand advertising business, covering three core platforms: the BZA Campaign Delivery System, BZA Management System, and BZA Compliance Review System. My primary responsibilities included end-to-end business iteration, feature development, and requirement delivery for the BZA Management System and BZA Compliance Review System. I also contributed to collaborative development for parts of the BZA Campaign Delivery System. On an ongoing basis, I was responsible for frontend performance tuning, code standard governance, and independently designed, built, and maintained the CI/CD automated pipeline for deployment. Key Achievements: Led frontend architecture and performance optimization for the BZA Campaign Delivery System. Through techniques such as on-demand resource loading, code splitting, request batching, and rendering optimization, I significantly improved page load speed and overall system stability. Participated in the full lifecycle of the BZA Management System and BZA Compliance Review System, from 0-to-1 architecture design and module splitting to business delivery. I unified project directory structures, component encapsulation standards, API request patterns, and coding conventions, boosting team collaboration and iteration efficiency. Independently designed and built the frontend CI/CD pipeline with custom YAML build scripts, enabling automated build, packaging, validation, and deployment. This simplified workflows, reduced manual operations, and cut deployment failure rates. Developed reusable business components, utility functions, and shared logic to form a foundational library, supporting faster iteration and development for subsequent advertising projects.
