At Alibaba Group, I led the design and delivery of a distributed order-processing platform using Spring Boot microservices, PostgreSQL, and Kafka. I owned API definitions, service contracts, and production rollout.
I engineered versioned REST APIs with OpenAPI and contract tests, and optimized high-read order queries with Redis caching, reducing average API latency by about 25%.
I automated container builds and deployment pipelines with Docker, Kubernetes, and GitHub Actions, and implemented observability with Prometheus and Grafana. I also helped refactor a legacy monolith into modular Spring Boot components.
Before Alibaba Group, I developed an e-commerce web application at GreenZone and internal inventory and order modules at NPL SERVICES INC. My work included REST APIs, payment integrations, database optimization, and automated testing.
