Over mij
I am a Senior Java Backend Developer with extensive experience in delivering e-commerce systems, migrating legacy services, and building reusable backend components. I have a proven track record of coordinating cross-functional teams and integrating AI applications into multimodal workflows. I am comfortable owning backend delivery and working across the full development lifecycle. Personal AI-assisted projects include English-learning apps, comic/short-drama workflows and an open-source LLM course platform.

Werkervaring

Technical Director

河北聪宝教育科技有限公司

Aug 2022 - Oct 2026 • 4 yrs 2 mos

Owned backend development and maintenance for a kindergarten-supplies e-commerce platform, working with one frontend developer. Built kindergarten-specific storefront access via QR codes, order management, WeChat Pay integration, and school dashboards restricted to each school’s orders. Used SKU-level Redisson locks for inventory deduction at order placement and RabbitMQ to close unpaid orders after 30 minutes and release stock. Developed and tested commission settlement and WeChat payouts; these capabilities were not used in live operations. Also handled day-to-day technical support across the company.

Java Developer

云袭网络技术河北有限公司

Jan 2022 - Jul 2022 • 6 mos

Migrated account, guild administration, operations administration, and order services from PHP to Java while the existing application remained in use. The old and new services shared a database during the transition. Retained some API contracts and redesigned others, coordinating endpoint changes and integration with the frontend developer. Built Jenkins pipelines for JAR-based deployment: code commits triggered test-environment builds and deployment, while production releases were manually triggered. Reduced deployment time from approximately 15 minutes to approximately 3 minutes.

Contributed to DingTalk ecosystem applications for performance management, official-document management, and quizzes (Dingdang Quiz). Initially combined backend development with project management, covering requirements discussions, task breakdown, development, and delivery coordination. Relocated from Beijing to Hangzhou in late June 2019 and focused on development rather than project management.
