RESUME

I worked as a software architect and have more than 15 years of experience. I worked as a software architect in the Lilee Systems, Inc from 2011 to present, where I designed and implemented the distributed FCAPS Framework and SMG product, which brought millions in revenue per year for the company. And I worked as a software architect in Huawei where I designed the next generation software platform of wireless product (NG_BTS), the software architecture of CBTC (Communication Based Train Control System) and ROSA (Wireless Software Platform). I was awarded President Award for the GSM BTS software reconstruction and Gold Medal Award for the new architecture in the wireless software platform in Huawei. I received my BS degree and MS degree in Computer Science both from Nanjing University in China.

WORKING EXPERIENCES

Software Architect in Lilee Systems, USA

Mar. 2011 - Present

Designed and implemented the distributed FCAPS Framework.

1.The distributed FCAPS(Fault/Configuration/Accounting/Performance/Security) Framework is a developing and coding framework. It belongs to management plane or control plane in the system.

2. This framework provides a master node and many slave nodes.

3.The master node is the FCAPS management center. The master node can configure all the slave nodes, it can also get the accounting/performance/fault/alarm data from all the salve nodes.

4.This framework also provide distributed CLI of the system. That is, the operator can configure/manage all the slave nodes at the master node using CLI.

5.The max number of slave nodes can be more than 50 thousand.

Key Design:

1. Distributed MVC(Model/View/Control) Framework, similar to CORBA(Common Object Request Broker Architecture) or DCOM(Distributed Component Object Model).

2. IPC Framework based on data model

3. Session & Transaction Framework

4. Paralleled programming, multi-threads program

Programming Language: C, C++

Designed and implemented the SMG (Service Management Gateway) product of PTC system.

1. The SMG is the service management gateway of the PTC system.

2. Positive train control (PTC) is a system of functional requirements for monitoring and controlling train movements as an attempt to provide increased safety.The American Railway Engineering and Maintenance-of-Way Association (AREMA) describes Positive Train Control as having these primary characteristics:

a)Train separation or collision avoidance

b)Line speed enforcement

c)Temporary speed restrictions

d)Rail worker wayside safety

3. The SMG is also the management center of the PTC system. It can manage all the nodes in the PTC system. That is SMG is master node, all others are slave nodes.

4. The SMG provides a session/job/task framework to manage the whole PTC system. The SMG can create different jobs to manage the slave nodes. The job type can be statue-probe, log-retrieval, command-execution, file-transfer, radio-activation, kit-management etc.

5.The SMG provides web management view. All the management jobs can be done on the web.

6.The max number of slave nodes can be more than 50 thousand.

Key Design:

1. Pipeline design pattern

2. Session/job/task framework

3. Threads pool

4. DB connection pool

5. Paralleled programming, multi-threads program

Programming Language: C, C++
