    I am a Java Web Developer, working as freelancer, mainly in Upwork. I am very passionate with Java and JVM technologies. 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’m a team leader of the team of java full stack developers capable of solving tasks of any complexity at every stage of the software development life cycle, from analyzing requirements and building architectures for startups to supporting and changing legacy projects. We specialize in developing a backend for mobile (rest/soap) and enterprise web applications or specific tasks that are better implemented by those tools that are supported by the Java language. We also have sufficient expertise and experience to develop a UI in Angular or React. We work with various relational databases (MySql, Postgresql, Oracle) and NoSQL databases (Mongo, Cassandra, Redis). As the primary tool, we use the Spring Framework. However, we have experience working with others (Vert.x, Micronaut, etc.) We monitor the quality of our code using tools for unit testing, static code analysis, and continuous integration/delivery. Also, we continuously review the code for vulnerabilities and performance issues. We develop cloud solutions with automatic deployment both on Amazon AWS or other cloud providers and on the physical servers of the customer.

    Hello there! Before talking about qualifications and professional abilities, I would like to introduce myself. I am David Gevorgyan and I am from Armenia. Taking web development as a profession not only fulfils my pocket but also my heart. I believe that people should do things in which they are good at or in which their heart lays. That’s why I chose freelance web development as my career because I believe I’m good at this and mas I am always honest and I am never afraid of doing hard work. I can give you money back guarantee and I can assure you won’t regret hiring me. Thank you.
