At Tencent Cloud, I built an internal SRE automation platform with AngularJS, JavaScript, and Spring Boot. It streamlined deployment and monitoring workflows, improved team operational efficiency by 50%, and maintained zero production incidents.

I redesigned the architecture of Endpoint Service, migrating it from Spring MVC to Spring WebFlux. The change doubled maximum RPS, cut memory usage by 50%, and enabled 10× higher concurrent connection capacity.

I optimized PostgreSQL schemas to eliminate 10× duplicated listener and health-check records and improve query performance by about 200%. I also resolved 100+ bugs and implemented 20+ features in an internal software management system.

At the University of Washington Bothell, I built LLM fine-tuning and reinforcement learning trading agents. My GRPO project improved returns by up to about 50% over untuned models and was published at the 2026 IEEE International Conference on Information Reuse and Integration.
