Java developers propel your project forward by engineering highly scalable, low latency applications across critical systems. Java developers contribute across all phases of the product lifecycle, ensuring that code is well written, testable, and efficient.
If you want to hire a Senior Java developer you should be evaluating someone with 3 to 6 years of experience working as a java developer. The strongest candidate should be experienced working with any of the following: Spring, Hibernate, Scala, Hybris, SmartGWT, Kafka, Hadoop, Cassandra, Spark, and Cloud computing systems.
Middle-level java developers need help understanding the patterns that can pinpoint them to bugs in the code. They have probably been through the whole development cycle at least once and seen the results of design problems and are learning how to avoid them in the future. Usually, they tend to be more likely to take a requirement at face value and not push it back when it has obvious problems or gaps. They have learned enough to know what they don't know and are starting to gain that knowledge. They are the workhorses of the programming world, they deliver probably 80-90% of the routine code and maybe 10% of the very difficult stuff.
Here, a candidate typically falls in the experience range of 0 to 2 years. Candidates who fit the bill should be good at writing readable and clean Java code. He/she should have a good understanding of JavaScript, Servlets, Servlet methods, and parameters.
Java can be found in almost every possible software application. Java is the server-side language for most back-end development projects, including those involving big data and Android development. Java is also commonly used for desktop computing, mobile computing, game design, and more.

Project: Shopping club.
prestige.ua was the most famous shopping club in Ukraine. I was involved in developing a new dashboard that was used by company’s departments: buyers, accounts, lawyers, call center and so on. Company had different shopping clubs in Ukraine and Russia, these clubs had their own backend (admin panel) and frontend (UI of the site) parts. And the strategy decision was to develop a new e-commerce platform for internal company’s needs, to manage clothes for all shopping clubs from a single admin panel. At the beginning, this project was writing on php with mysql DB. The company’s plan was to migrate all available data to Oracle BD and write new backend on java. Some parts of backend finally were re-written on GWT.
