My experience mostly in developing Software As A Service (SaaS) platform, business computing and information system area, using Bootstrap, Angular JS or JSF as UI Components or web framework, Spring Core, Spring MVC or JBoss Seam as Restful API endpoint and or Integration framework, and Hibernate as favorite Java Persistence API (JPA) implementation wrapped by Spring Data component. If my clients requires no casual application or web server, I like to use Spring Boot for simpler development and deployment of the application. I am also interested in database design and software design. I believe that great software not only mediocre work of typing, but also comes from thoughtful process. I believe in TDD, and also believe that tests code must be written, organized as good as the source code it self and is integral part of the source code. I am a quick learner, and In my spare-time, I am writing some personal open source project and small proof-of-concept about java-related stuff in my GitHub public repository. My primary machine is linux desktop with 1TB NVMe SSD and 64GB or RAM. I have macbook pro 15 for testing purpose and to allow me mobile occasionally, if needed.
