Enterprise-scale services

There are a number of qualities we have as a software provider that make us a Java development company in every sense of the term. This includes the scale and number of the Java development projects we have implemented, the breadth and quality of our Java service offering, and the grasp of Java knowledge and skills our engineers have.

Being an enterprise software development company, throughout our history we have learned to harness the full potential of Java to solve complex tasks. Coupled with the nearshore benefits our location in Eastern Europe creates, our skills and experience make us a worthwhile candidate provider for anyone looking to go nearshore with their Java development needs.

Our case studies

Certainly, the best proof of our mastery in Java is our Java project portfolio. It features several dozens of large-scale, enterprise-grade Java development projects we have implemented for Western-European Telco heavyweights, as well as an array of smaller projects for Western and Middle-Eastern clients in the Real Estate, eCommerce, and other verticals.

Our involvement in the listed above projects has helped us become conversant with using Java to develop Billing, Ordering, Rating, Invoicing, CRM, Document Management, Time Management, and other diverse functionality.
