Projects
2022.04 – 2025.03
Yizhi Psychology
Technical Manager / Project Lead
A comprehensive psychological assessment platform with a B2B admin console for enterprises and a B2C assessment mini-program for end users, covering online assessments, report generation, third-party payments, AI customer service, and big-data operational analytics.
Architecture
Business services: Spring Cloud Alibaba microservices, containerized on a self-managed Kubernetes cluster on Alibaba Cloud ECS
End-to-end delivery: Owned the product from zero to launch, defined milestones and iteration plans, and coordinated product, backend, frontend, QA, and data resources, reaching a 95% on-time delivery rate. The architecture mixed several Alibaba Cloud services with self-managed clusters, requiring careful coordination of deployment order and environment stability.
Risk identification and control: Identified launch risks in the AI customer service system (response latency, model hallucination) and prepared fallback plans and a canary release strategy in advance, bringing the new feature live without disruption.
Cross-team coordination: Aligned backend, frontend, algorithm (AI model fine-tuning), and data (big-data pipeline) teams on interface contracts and delivery milestones, driving the integration of AI capabilities and the data platform into the existing system.
Data requirements: Coordinated resource scheduling and integration work for the big-data infrastructure (Kafka ingestion, Flink stream processing, Alibaba Cloud Quick BI reports) so that operational reporting needs were delivered on time.
Process discipline: Introduced GitFlow collaboration conventions and code review, and established a release checklist, reducing the production defect rate year over year.
External integrations: Worked with the WeChat Pay and Alipay payment channels, coordinated business and legal teams on merchant qualification applications, and designed idempotent callbacks that kept payment errors at zero.

The Winshare Online franchisee system, supporting day-to-day operations for nearly 200 franchisee stores on platforms such as Tmall, JD.com, Dangdang, and Amazon — product synchronization, order capture, and return/exchange settlement.
Key contributions
Multi-store operations: Handled day-to-day technical operations for nearly 200 franchisee stores, resolving price synchronization errors, order capture delays, and return/exchange settlement discrepancies to keep franchisee businesses running.
Peak-event support: Helped design the inventory lock plan ahead of the Double 11 sales event and provided overnight support, coordinating with operations on capacity expansion to keep systems stable during the promotion.
Exception handling: Resolved the order and settlement discrepancies that promotions ending left behind, established an SOP for exception handling, and cut average resolution time by 50%.
New business support: Worked with the operations team to extend pre-sale functionality, adjust order and payment logic, and publish pre-sale products to platforms such as Tmall.
