LineBot Stock Notice (種花裁金)
The project was created because the website I was used to was no longer available. Therefore, I integrated the Line chatbot and web crawler via Node.js and heroku The application can send daily notices about the buy-sell rank. Through this project, I save time opening the stock website daily and it only sends news I want to read.

HTML5 Web Game (格上租車)
This project is delegated by my friend. He is working at 格上. We have to develop 2 web games (catch coins via left-right buttons, shot the monster via the cannon) to increase user engagement and consume the points they got.
We not only developed the game but also developed the administrator site for management users and export reports.

E-Commerce Project (山水)
This is an outsourced project and was developed while waiting for a response from the interviewing company.
The main feature is an e-commerce system. Including the shopping cart module, orders management module, and members module.
In addition, integrated the promotion module and the promotion notice module (Newsletter).
The payment services used an API provided by Hua Nan Commercial Bank directly. I have the experience to integrate the payment APIs many times, so I could design the payment flow in a short time.
