Used smartEngine2.0 to arrange internal state machine. Used SchedulerX2.0 to trigger timed tasks.Supported stability of cloud retail delivery during S class promotions. Untangled core business scenarios, made plans for pressure tests and capacity enlargement. Set bcp alarms and flow-limit plans.2.LST Purchase & Inventory[Technical Project Manager & Developer]Managed project, designed technical solutions, business model and state machine.Implemented business isolation based on TMF3.0 framework. Used Metaq to decoupling different business scenario. Used HSF interface for internal service call and decentralized mtop interface for external service call, which supported multi kind of terminals.Promoted five large version releases without any glitches. Increased UV/PV more than 10 times than before releases. Improved and kept large amount of purchase.3. Regional retail – delivery[Developer & Algorithm Designer]Developed the project, implemented and enhanced apis for regional retail, designed algorithms and supported capability during promotion.Accessed multiple same-city delivery capacity, formulated multi-stage delivery networks. Used time schedule to solve the warehouse flow-limitation.Designed an algorithm to automatically generate service scope precisely(±20 meters) with high performance (lessthan 10s with single thread for each store) based on the distances for stores in new retail services. Designed pre-buy delivery determination service based on ray-casting algorithm. Show less
