- It was my first commercial web development. I learned how to make a commercial website. I had to worry about various issues, such as privacy, security, bugs, backup system, source code management, and alert system.
- Security was important because payments were made on the website and money was handled. I learned about hacking techniques that are frequently used, and I learned about the security of web servers.
- Due to the online payment environment in Korea, we could not implement the service we wanted. Through this process, I learned about the online payment process in Korea.
