Full-stack Java Developer

Indonesia - Tests: 11 - Portfolio: 3

I am a Java Developer, working as freelance Java Developer, mainly in Upwork. I am very passionate in Java and java-related technology. My experience mostly in business computing and information system area, using Spring MVC or JSF as web framework, and Spring Core or JBoss Seam as Integration framework, and Hibernate as favorite Java Persistence API (JPA) implementation. If my clients requires no casual application server, I like to use spring-boot backed by spring-data platform for easy to use and more "microservice oriented" approach. Mostly using JUnit for testing, except for JBoss Seam, I am using TestNG which is bundled together with JBoss Seam distribution. 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 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. During my work, I am using my Thinkpad T430s with Intel i7 processor, 16GB of RAM, 256 SSD and 23 inch external monitor that running latest stable version of Ubuntu Linux. Communication is important in remote work, and for this purpose I have 2 link dedicated internet connections to my workspace. If you need my detailed skill abilities, below is what I have experienced in: - JPA 1.0, JPA 2.0, with Hibernate. - Bean Validation Specification with Hibernate Validator. - Dependency Injection with Java DI (JSR-330), Java Context and Dependency Injection for Java EE Platform (JSR-299), and Spring Core as most popular (but non-standard) Java Dependency Injection Framework. - Java Web Framework with Spring MVC and JSP, or Java Server Faces (JSF) with Facelet and Primefaces. - Spring Boot, Spring Data stack. - Java Web/Application server with Tomcat, JBoss AS/Wildfly, or Websphere AS. - Logging with SLF4J as a wrapper to Log4J or Logback. - JUnit or Test NG as testing framework. - Ant, Maven or Gradle as build and dependency management tool. - HTML 5, CSS 3, JavaScript, JQuery, Twitter Bootstrap, and transparency.js - Third Party API such as Xero API, Open ERP Java API, Braintree Payment API, and Social APIs (Google, Twitter, Facebook, GitHub, etc.) - Linux/Unix or Windows. - MySQL, Postgre SQL, or Microsoft SQL Server for RDBMS. - Couchbase for No-SQL solution. - Elasticsearch stack or pentaho for data integration, advanced search, reporting and data analysis solution.
