# Working Experience
## Software Engineer  @Google
    - Google Distributed Cloud - Hosted. Google Private Cloud (GPC)
    - E2E Cloud Infra Development from day-0 to day-2.
    - Baremetal Machine & OS Management
    - Cluster, control plane.
    - Cluster Node Upgrade.
    - System Manager, AddOn Manager, Multi-Tenancy

## Software Engineer Intern  @Google
    - Istio, Envoyproxy (Cloud Native, Service Mesh, Service Proxy)
    - Envoyproxy: Introduce quick visibility of blocking listener/cluster during warming up process of 
      downstream unready listeners by target aware watcher callbacks to init-managers.
    - Provided early-starting strategies for listeners with filter chain place holder to avoid blocking and 
      decrease response latency. 
    - Enabled dynamic listener filterchain/dependency update on new connection requests, with automatic connection retrial callbacks in an approach of worker-master-worker thread communication.
    - Istio: Enable more strategies at istio api and improve the scalability at large mesh, reduce the resource 
      usage per instance.

### Software Engineer Intern @ Google
Jan 2020 – Jan 2020 | Mountain View, California, United States
- Cloud Native Service Mesh Open Source Project: Envoy-proxy(C++), Istio(Golang)
- On-Demand Filter Chain - Service Mesh Proxy listener Discovery Service, eliminated time waiting for inactive dependencies
- Breaking changes to the envoy proxy thread mode. Nonblocking worker-master-worker thread locks.
- Designed and implemented target-aware callback watchers - brought quick visibility for blocker dependencies/Certs of Envoy init-managers.
- Enabled config dumping for unready targets of blocked listeners during warming process with Protobuf message.
- Provided early-starting strategies for Envoy listeners with placeholder components(filter chains) - avoided blockers and decreased response latency.
- Enabled dynamic listener filter-chain dependency update on new connection requests - automatic connection retrial callbacks - worker-master-worker thread communication.
- More Istio APIs - improved the scalability at large mesh and reduced the usage of resources per instance.
