• Developed core products and dashboards to enable previously manual operational processes in AWS infrastructure to be templated, versioned, automated and 100% monitored. This significantly reduced the operational load and improved operational and engineering excellence, like BOM validation, risk buy ordering, rack configuration, program tracking, as AWS Infrastructure scales both the complexity and the quantity of new components in server racks and data warehouse development

• Owned primary architectural artifacts for the projects, including distributed storage systems, down-stream event-based notification (routine jobs, S3 updates) and performance metrics. Streamlined the DynamoDB / RDS / PostgreSQL data storage and optimized React frontend rendering by 10X

• Led the efforts to migrate high-impact projects from python2 to python3

• Introduced and developed the automated end-to-end testing

• Lead scrum team to build scalable software solution to design ASML YieldStar overlay targets and increase overlay control accuracy in lithography process

• Deliver several features to boost the automatic workflow of target design and results analysis, which helps close 5 major deals generating >$60 million in revenue

• Architected large-scale enterprise applications and applied Domain Driven Design methodologies to fast develop softwares with complicated domain knowledge

• Manage multiple projects in Agile best practices and facilitated the communications of a core team of designers, architects and developers worldwide

• Responsible for Java/JavaFX implementation of the enterprise software which provides semi-conductor overlay solution

• Developed the Thrift RPC APIs to support data analysis and implemented the related micro-service module
