    Our Java Technology Stack


    This is an object-relational mapping (ORM) framework that’s highly optimized for data handling. Its main strength is working with relational databases and paradigm differences.

    Google Web Toolkit

    GWT is the perfect tool when our Java developers have to focus on Ul design rather than on scripting. That’s because GWT takes Java code and turns it into browser-friendly packages that help scale-sensitive app development.


    Apache Spark is a data processing framework that’s perfect for solutions that have to perform intensive processing tasks on large datasets. Thus, it’s the perfect tool when working on big data and machine learning projects.


    Struts is an enterprise Java framework that has a centralized configuration and that helps in reducing development times. It also offers simplified testing and it’s easily expandable through plugins, which turn Struts into a good option for Java developers.


    This modular and lightweight framework is highly versatile and our Java developers use it for many different projects. It boasts an MVC architecture, top security features, and can be used on specific project layers or across the entire scope. It’s a swiss knife.


    Play Framework is an open-source web application framework that makes it easy to build web applications with Java. It is written in Scala and usable from other programming languages that are compiled to JVM Bytecode, e.g. Java

    Platform Independent

    One of the main advantages Java offers is a platform independent feature. Java is probably the best programming language for cross-platform applicants.


    Java powered products can perform various tasks at the same time, allowing developers to write complex interactive applications.

    Shorter time-to-market

    With a well-designed intuitive set of API’s, programmers can write code faster with fewer bugs, thus enabling to offer relatively short time-to-market periods.


    As an object-oriented model, Java enables rapid development of scalable and complex applications that are easy to extend. With the help of object-oriented units called classes, the program working on Java can dynamically extend itself in order to expand its functionality.
