Managed around 50 Engineering Managers, Project Managers, Product Managers, Data Scientist and Software Engineers.The Payments modernization is done during the COVID-19 and site traffic is dramatically lower compare to normal business and many other domain teams are also focus on modernization. We have used different design strategy compare to Identity for both moving faster and resolving some long term pain points purpose:1. ZERO adoption efforts design for Buyer Payments for taking traffic quickly by providing both new interfaces and back compatible interfaces in API level.2. Redesign some very legacy functions in Seller Payments with domain team adoption to greatly simplify the architecture design and decrease maintenance efforts in long term. Only provide new interfaces for such cases.3. Use one time data migration strategy to make the Cloud database as golden data for better performance.4. Dual-write data from Cloud to On-Prem to support legacy applications reading data directly from Oracle database.5. Some Microservices are written in Kotlin language which makes the code more shorter and maintenance efforts smaller in long term. Show less
