What I've done.

In the late 1990s, I started HTML with CGI, Perl, and used Flash animation with ActionScript. In the early 2000s, mainly used Linux, Apache, PHP, MySQL. After joining a company, handling with Windows server, IIS, ASP, C#.NET, SQL Server. The development team used the tool based on the agile methodology for collaboration with each other. To fast establish service used various CMS such as ZeroBoard, XE, WordPress, and Textcube, and launched WebView based hybrid mobile applications. Recently, configured MariaDB and Redis based on the Laravel framework on Nginx, controlled version with Git, and CI/CD to distribute automatically via helm cart as cloud service composed of Kubernetes load balancer using Jenkins to build, test, and deploy.

Not willing to change are bound to be isolated

Started web development with CGI and Perl in 1997, and have experienced a variety of web frameworks. Keep trying to learn all about the information technology industry as always.

Current Focus

Since 2010 moved to the US, mainly carried out e-commerce related projects to integrate using RESTful APIs with CMS based on WordPress, Joomla!, and Drupal. Currently interested in front-end JS platforms such as React.js, Vue.js, and mobile native technologies such as Vue Native, React Native, ionic, and Flutter, and also interested in NoSQL such as MongoDB and MariaDB for fast and light data processing. As the development of cloud services improves development and operating environment, it is also very interesting to use DevOps through AWS, GCS, and Azure. Open-Source on GitHub has been interested in sharing sources and feels meaningful in contributing to various projects.

Polyglot is no longer a matter of choice
