In the first year, I created some web services using various languages, such as Perl, PHP and Ruby as an internship. In the second year, I created some web services as a Ruby/Rails programmer. In the third and fourth year, I started up a new business as a manager and a programmer. At the time, I did set up everything in the system including the server(AWS), network, back-end and front-end. I followed the idea of DDD to make the system scalable. Of course, I designed testing code as well.
