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. 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: - Software Design, Database Design, and microservices/Micro-services/micro services architecture. - 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. - Generated / scaffolding web application using JHipster. - Java Web / Application server with Tomcat, 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, transparency.js, and angular / angular.js - Third Party API such as Xero API, Open ERP Java API, Braintree Payment API, Stripe Payment API, and Social APIs. - Linux, Mac or Windows. - MySQL, PostgreSQL, Oracle, or Microsoft SQL Server for RDBMS. - Couchbase or Mongo DB for No-SQL solution. - Elasticsearch (ELK) stack or pentaho for data integration, advanced search, reporting and data analysis solution.

    I excel at analyzing and manipulating data, from megabytes to petabytes, to help you complete your task or gain a competitive edge. My first and only language is English. My favorite tools: Tableau, Alteryx, Spark (EMR & Databricks), Presto, Nginx/Openresty, Snowflake and any Amazon Web Services tool/service (S3, Athena, Glue, RDS/Aurora, Redshift Spectrum).

 Apache Spark™ 2.X - Tableau Desktop Qualified Associate I'm looking for one-time and ongoing projects. I especially enjoy working with large datasets in the finance, healthcare, ad tech, and business operations industries. I possess a combination of analytic, machine learning, data mining, statistical skills, and experience with algorithms and software development/authoring code. Perhaps the most important skill I possess is the ability to explain the significance of data in a way that others can easily understand. Types of work I do: - Consulting: How to solve a problem without actually solving it. - Doing: Solving your problem based on your existing understanding of how to solve it. - Concept: Exploring how to get the result you are interested in. - Research: Finding out what is possible, given a limited scope (time, money) and your resources. - Validation: Guiding your existing or new team is going to solve your problem. My development environment: I generally use a dual computer-quad-monitor setup to access my various virtualized environments over my office fiber connection. This allows me to use any os needed (mac/windows */*nix) and also to rent any AWS hardware needed for faster project execution time and to simulate clients' production environments as needed. I also have all tools installed in the environments which make the most sense. I'm authorized to work in the USA. I can provide signed nondisclosure, noncompete and invention assignment agreements above and beyond the Upwork terms if needed. However, I prefer to use the pre-written Optional Service Contract Terms www [dot] upwork [dot] com/legal#optional-service-contract-terms.

    I am an Elixir/Golang/Python/Ruby programmer and Linux System Administrator. I had spent 22 years in the corporate world as a developer and linux administrator, working in the office. 8 years ago I jump to working remotely from home as a freelance developer. I have built apps for my customers ranging from locally in Nueva Esparta, and all over the world. I take pride in my work and the majority of my customers bring me repeat business and referrals. I feel I have been successful, not just because of my web programming skills, but because I am a reliable and dependable web programmer that can be trusted to follow through with my work. I enjoy working directly with my clients, rather than having project managers involved. Even though I seldom meet my clients in person (due to geography), I am able to effectively communicate via email and chat to complete the website development project to their specifications.
