Dailyvita, Software Developer May 2017 – Present

Developed the Office Automation System (OA) based on PHP, Apache and MSSQL. In the company there are lots of subsystems such as Inventory subsystem, shipping subsystem, selling subsystem and so on. The OA regularly grabs and stores all related data by APIs provided by subsystems. Then it analyzes all data to develop a good and flexible sales strategy for the company. The OA system provides customer service the ability of search shipping status of every package shipped by our warehouse. It also can obtain the selling prices of every product which we focus on from our competitors to generate more competitive prices based on the minimizing prices which we calculate.

Developed Scanning System. I developed the system to record tracking numbers when and by whom they are scanned. Combining the scanning data and other data from shipping subsystem and inventory subsystem, the system is able to provide the managers the real time information of warehouse and office. It also can monitor the efficiency of every worker.

Contract Developer – Freelance Jul 2016 – Present

Food ordering system: This system provides customers and restaurants with online services. The system is divided into three parts: terminal software, restaurant management system and web server.

Web server is to provide terminal software and restaurant management system with data resource. Considering the requirement of system and the resource what I have, Web server is based on platform which amazon provides. Lambda, API gateway and dynamoDB that is a database which amazon provides are used in the web server. I used swagger file to define all the APIs of server. And I used maven to organize and code the whole project in Java with eclipse on Ubuntu. So far, I am done with skeletal system. The web server can provide users and restaurant management system with data resource. (Repo:

Terminal software is used to provide users with ordering service. Users can look up the specified restaurant by either users’ location or restaurant style. After completing and update the order to server, web server will generate a unique number to identify. Customer can go to the restaurant and show the unique number to waiter. And restaurant can also prepare the food ahead. I am working on the application now. (Repo:

Car Navigation System: This system provides customers with navigation services including traffic information display, multiple kinds of navigation services. My responsibility is to develop and maintain the terminal software based on WinCE in C++. Because of the limitation of hardware, the multiple-process mechanism is applied on this application. Because of protocol which the hardware only has some EVENT type messages open to application, I developed the process which is used to manage multiple processes by receiving the EVENT messages from hardware. These processes include the process of dial-up, the network process, and the navigation process. I used the file mapping and mutex to manage the communication among multiple processes. So far, the multiple-process version has passed the test. Due to complication of software and better support from vendor, we are considering to replace multiple-process with multiple-thread.
