Blockchain integration

• Built bloXroute Cloud-API with Go, supports streaming blocks, transactions for Ethereum, BSC and Polygon network base on web-socket connection and gRPC framework. Design and built features including private transaction, transaction status notification and gas fee bump.• core backend service for bloXroute BDN, including relay network and gateway based on Ethereum P2P Networking Protocol. (Golang)• Developed SDN server for managing large global distributed system (the heart of bloXroute BDN). It coordinate account authentication, monitoring bloXroute gateway and relays connectivity, provides client-side reverse proxy and enforcing firewall protection.• Automated E2E and regression testing software for bloXroute Cloud-Api and Gateway services, and integrating into CI (Circle-CI)• DevOps works include tasks of troubleshooting, hosting and maintaining blockchain nodes/validators(Ethereum/BSC/Polygon/Solana) and bloXroute relay/gateway with AWS services.

• Built a high-performance and highly-scalable micro services for internal travel booking system at Tencent. Built with Java Spring Cloud Framework + MySQL Database.• Responsible for implementing message notification service with RESTful API and testing units with Apache Jmeter.• Developed ML algorithm to optimize the attendance system utilizing data from building access control system, improved 40% of the accuracy and efficiency of calculation for the manager and human resource.

• Researched and built the next generation Exascale Supercomputer, closely worked with the manager of ALCF (Argonne Leadership Computing Facility) by conducting weekly report and presentation.• Built an advanced data staging server for the large distributed data centers at ANL, by developing an intervention-free data staging platform with Python Flask API + Redis DB + Celery Task Queue, allowing Supercomputer scientists to conduct research experiment securely with GLOBUS OAuth supports, and efficiently transfer data with GLOBUS Transfer API.
