• Building LinkedIn's robust and scalable distributed Traffic Infrastructure

• Service mesh

• Reverse proxy (Envoy, Apache Traffic Server, HaProxy)

• Service discovery

• Load balancing

• Traffic routing

• Application development in distributed system based on cluster working environment with intensive data process, involved with data serialization and deserialization, calculation, network transmission, UI display (Python + QT), etc;

• Parallel speedup for the key features, as well as network traffic reduction, and memory and performance optimization;

• Embedded system involved with board evaluation, calibration system and diagnosis system development;

Leader of Infrastructure team including Parser team, Front-end team, and VerilogA team, to develop and maintain infrastructure related work and build database for circuit simulation, as well as hundreds of features based on the circuit database:

1) Parser to support Spice and Spectre netlist;

2) Elaboration including building circuit hierarchy and connection, and expression evaluation;

3) Kernel database including flatten and partition;

4) Circuit optimization including fold, compress, short, reduction, etc. to improve performance and reduce memory;

5) VerilogA compiler, including latest VerilogAMS LRM syntax support, VA database and elaboration, C code dump and dynamic library build, run time library support;

6) API development to integrate system into customer platform both for Linux and Windows;

Software platform develop for ZTE handset, lead kernel of WAP browser development including analyzer ( wml, html, css, javascript, etc ), display layout (flow and algorithm), http features like https, cache, cookie, etc.
