Custom Java Development

Romexsoft Java developers, along with QA specialists, DevOps engineers, UI/UX designers, business analysts, and other professionals, provide full-cycle, custom product development with high security, availability, and performance demands.

Java Web Application Development

We create web applications using flexible, reliable and secure Java Spring Framework. There are options to create either a versatile REST API with a combination of any UI framework, or a classic MVC application with a combination of Thymeleaf or Freemarker server-side Java template engine. We have been providing technical support and working with regular customers for over 17 years.

Java Mobile App Development

At Romexsoft, we have talented Oracle-certified professionals who combine their knowledge and expertise to develop native Android mobile applications.

Cloud Application Development

With the help of Spring Boot framework, we can quickly develop microservice-based architectures; and with the help of Spring Cloud framework, we can easily set-up applications in the cloud. Our cloud-based applications are cost-effective, flexible and highly secure, and our integration services allow you to use your cloud applications in only the best public cloud environments like AWS (Amazon Web Services).

Time-to-Market. Java has a well-designed reach API with a large ecosystem of well-tested libraries and frameworks for any use case. It is both easy and convenient to design, implement and deploy your applications in Java.

Distributed computing. Java is designed as a distributed language and allows you to have several computers working simultaneously on one network. On top of that, Java has the whole ecosystem of Big Data processing frameworks like Hadoop, Spark, Sockets, Remote Method Invocation (RMI), Multicast Sockets, Kafka, and Message Passing Interface (MPI).
Platform-Independent. Always a valuable benefit in developing any application.

    Why Do You Need Java After All?

    Reduced Time-to-Market

    Java is a mature object-oriented language, which allows creating modular programs and reusable code. The intuitive set of APIs comes as another time-kicker. Programming in Java tangibly shortens the overall development time and cuts the costs.

    Platform Independence

    Java is a beast of many faces and allows to run the same application on different systems – an indispensable point for a modern software solution. In fact, Java succeeds at this point as it is independent on both levels – source and binary.


    Developing high-load applications using Java is easier and more efficient as the technology allows programs to perform several tasks simultaneously within a single program.
