Challenge

As a market leader open for innovation, Freenet Group decided to proactively handle legacy software migration and modernization. The original systems were built on a technology stack no longer sufficient for Freenet Group’s business needs.    

Main Goals

  • Preserve the business logic for all the applications
  • Migrate application to new technologies – Java 11 and Spring Boot framework.

Solution

Edvantis engineers helped Freenet Group adopt microservices architecture for their products, update legacy libraries and perform extensive code refactoring. To double-check if new technologies are implemented correctly, we ensured full test coverage. 

Technologies Used

Java 11, Spring Boot


Edvantis has intelligent people on board, competent and ready to get the job done. Their professionalism and approach to development has made for a good experience thus far, along with the speed and accuracy of their work.
