Senior Java Developer

Russia - Tests: 23 - Portfolio: 4

I am Java backend developer with some frontend capabilities. I have 7+ years of java backend development, mostly involving complex integration between various computer systems. I have strong Java SE, Java EE and Spring framework background, rich experience in integration-related projects. My common project role is to develop the design and full implementation of backend for some web application and vast variety of integration services providing data necessary for application work. These integration services often communicate to other systems using various APIs, data formats and information exchange protocols. I have good knowledge of SQL (and PostgreSQL dialect in particular) and I mostly use PostgreSQL as relational database in my projects. I also have experience as portlet developer for JSR-168 and JSR-286 conforming portals like Liferay or IBM WebSphere portal and a minor rich internet application frontend developer experience using MVC javascript frameworks like Ember.js and Angular. One of my current projects use Elasticsearch as non-relational data storage so I have good experience using elasticsearch in production for faceted full-text search and complex data aggregations. My preferred OS for development and application deployment is Linux, so I have decent linux administration skills. I'm interested in Rust programming language and trying to contribute to rust projects on GitHub as my hobby. My notable Upwork test results: Top 10% in Advanced Java Test Top 10% in SQL Test less
