Main work is to develop and establish a game platform, which contain verious thirdparty games and multiple service, such as SMS, money transfer...etc.

Import CI/CD is simply try to solve some classic wrong situations. To do that, I took lot of time on learn how it work, which improved my skill on Linux and Jenkins. Although the result is not good as expected, CI/CD still have some benefit on code quality.

We can not really benefit from CI/CD, because we still have some work not yet finished: database migration, test coverage...etc.

The most I've done is to improve efficiency of back-end system. To do that we imported reddis cluster and upgraded some image processing tools via Node JS. We also refactored some program for e-book reading system.

Before I'm leaving, my biggest project is to design and develop a item manage system for a online shop. Unfortunately, this project is somehow unacceptable by C.T.O, who always asked me to develop a public product lunch system... I've had no choice but close it.

Major mission is to refactor and maintain system of reverse logistics. We worked with colleagues in Shanghai and use restful API to exchange data from our online shop.

Have tried to import scrum when I was promoted to team leader. This attempt failed because of high coupling program.

I was also assigned to refactor the high coupling core code. Unfortunately, they shut down this develop team (and this project as well) after an acquisition.

In ERP system, our team was in charging of providing contract data (more than 10k suppliers) to other subsystem and data for balancing account.(at least 10M rows of data per month).

Challenge of contract system is to make sure system have high flexibility to facing different charging methods. After we rebuilt the system, it can provide charging methods depend on item categories. A colleague and I redesign whole db schema for that.

I was also the main developer while we rebuilt the system of balance account. It was made to calculate much more correctly and efficiently.(Accelerate this subsystem about 100% by apply design pattern: factory)

Experience of developing websites from void. Hand made everything except graphic.

We do solve lots of problems in these handy work. Some were technical aspects, such as XSS, Sql Injection. Other were much complicated, such as hackers, DDOS and so on. Fortunately I had good colleagues to solve these together and make them become useful experience.
