Professional Experience

1. Software Developer (C# ASP.NET & database) at Mind Chemistry Apr.

2013 - Present

. Design a new team member management system for the Company using C#

ASP.NET and SQL.

a. Design the web system using Visual Studio, C# and ASP.NET. The webpages

are designed to coordinate with the SQL database safely and reliably.

b. Create a new relational database system using SQL database to store

every member's account information, meeting schedule, stock status, etc.

The data can be viewed and updated through the web pages.

c. Using C# to synchronize the data in the database with data in TFS. The

authorized users can use the web pages to update account information

and manipulate data in the TFS.

. Building the data layer for the Hydra Project using SQL and XML

database in Agile framework.

a. Design the data model schema for the Hydra Project.

b. Create XML wrapper code and fix build middle layer wizard.

c. Create integration and unit test for data layer.

2. Projects written in other languages (Java and C++)

Mar. 2012 - Present

a. Design a path finder and random maze generator in C++. In path

finder mode, the program implements Dijkstra's algorithm to find out the

shortest distance between two points. In random maze generator mode, the

program can generator a maze using Kruskal's algorithm. All of the data is

stored in the heap data structure, which also needs to be included in the

program.

b. Design word game Boggle! in C++ and implement algorithm of backtrack

recursive programming. The program uses recursive to determine whether the

player input is valid or not. Then the program can find all the remaining

words using recursive.

c. Design game Yahtzee! in Java. The program can control the rolling of

dice to be random. With player's clicking mouse, the program can judge

whether the operation is allowed or not following the rule. With different

results, the program can calculate the points automatically and determine

the winner.

d. Design NameSurfer Program in Java using GUI. This program displays

the popularity of an input name in last century using a graph. The program

first extracts the data from the database and stores the data for each

name in the program. When a play types a name in the GUI input, the

program can display a graph showing the ranking of popularity versus time

in a grid. When the size of the window changes, the program would

automatically redraw so that everything exactly fits in the window.

e. Design game Tetris in Java using modular programming theory in OOP.

Every file is well designed to perform its functions such as moving,

rotation, sanity check, etc.

3. Part-time LED power electronics engineer at Solite, Inc.

Apr. 2013 - Present

. Design and build the circuit for high-current LED circuit.

a. Select appropriate component rating value to meet the output requirement

(32V, 2A) .Design the schematic and PCB layout for the circuit.

b. Design EMI circuit to reduce the influence of the EMI.

4. System control engineer internship at ABB China

May 2012 - Jul. 2012

. With Matlab Simulink and Simpower, build models for Metro high voltage

circuit and components, including power supply, traction and auxiliary

converters based on typical topology. Make GUI program for these models.

. Run simulation for situations of normal operation at different modes and

for failure modes. Select key components (e.g. fuse, line conductor, DC

link capacitor) based on the simulation.

5. Thesis research on electrical high voltage engineering.

Feb. 2012 - Present
