Business Challenge

  • Client
    HDI Group
  • Industry
  • Ongoing Partnership
    since 2021
  • The client needed a transformation from an old application and the possibility to use new technology. The technology used so far was about to lose support. There was a need to implement a better alternative.
  • Eclipse RCP was used for a long time, and it didn’t work well and didn’t support the client’s business operations making everything inefficient and slow.
  • Our partner needed a web-type technology.
  • Time-to-market was very long, and there were also a large number of bugs. The client had to wait up to 3 months for a fix, and sometimes there was no assurance that a particular bug will be fixed.
  • The transformation involved a complex, business-critical application for end-to-end management, editing complex contracts, and creating policy documents and invoices for the company’s corporate clients.
  • Releases were rare and very expensive.
  • The client needed a tech upgrade – they wanted to keep using Java.

Our solution

  • Hicron provided the experts in the field and selected Vaadin as the main technology for implementation.
  • We introduced full automated testing.
  • Hicron selected Scrum as a management model. We hired testers thanks to our expertise, and we worked better during the development phase due to the Quality Assurance process.
  • We launched high-quality software, which allowed us to do everything on the web without having a separate desktop application.
  • Thanks to continuing the app development in pure Java, HDI were able to reuse all of its current business objects, data containers, and more.
  • The team focuses on front-end technology transformation from Eclipse RCP to Vaadin.
  • To provide further new functionalities, the old Java code was refactored and upgraded to Java 8.



High software quality and smaller number of reported bugs.

quality assurance testing

No additional costs due to the fact of not having to upload everything to new devices. 

legacy update

Much faster time-to-market and bug fixing.

Thumb up

Efficient automated testing.

Modern UI, & quick implementation of changes – 2 weeks instead of initial 3 months


Thanks to the introduction of modern technologies we simplified HDI’s application – almost a 50% reduction in code!

Technologies we used:

Vaadin, Mockito, JUnit4, TestBench, RCP, Java8, Oracle DB, Eclipse RCP, SWT, JPA, IBM Websphere, Maven, H2 DB, Camunda BPM S, plunk


  • Java Developers
  • Quality Assurance Engineer
  • Test Lead
  • Business Analyst
  • Agile Delivery Lead
  • There were 2 mixed teams in total (client team and Hicron team) – one dedicated to Vaadin transformation and one for the business part.

Who can benefit:

  • Companies that are struggling with outdated solutions. We have an experience in transformations from old to new systems and complex business cases.
  • Businesses that are looking for faster time-to-market of their product, transition to web technology, or improved UX/UI.
  • Companies looking for a transformation partner to propose the best solution and consult the available options.
  • Clients who want to improve the quality of their programming and software development, or want to introduce automated testing. They require understanding and systematizing the needs of their customers and their own through complex business analysis.


What our partners say about us

After carefully evaluating suppliers, we decided to try a new approach and start working with a near-shore software house. Cooperation with DSS from Hicron was something different, and it turned out to be a great success that brought added value to our company.

With HICRON’s creative ideas and fresh perspective, we reached a new level of our core platform and achieved our business goals.

Many thanks for what you did so far; we are looking forward to more in future!
