What skills or competencies your team needed to do the required work
Development of web applications
Our experience in web application development allowed for the transformation of ES-Application and the creation of ES-Portal as advanced web applications. Thanks to this solution, we eliminated the need to install software on individual workstations, which reduced IT infrastructure maintenance costs and enabled easy access to the system from any location and device with internet access. The benefit is increased system availability and improved user comfort, both for employees and Energosystem customers.
Custom software development
Our knowledge in custom software development allowed for the transfer of complex algorithms and business logic to a modern platform. As a result, the new system significantly improves user convenience and flexibility in adding and developing application functions. This allows the system to easily adapt to changing user needs and enables efficient implementation of necessary changes.
QA tests
Meticulously conducted quality assurance (QA) tests allowed us to detect and fix potential problems at various stages of the project. Through unit and integration tests, we ensured the reliability and stability of the ESYS 3.0 system. Our knowledge in QA allowed for minimizing the risk of failures, which ensured high-quality service and satisfaction of Energosystem customers.
Use of web technologies
Thanks to the use of modern web technologies such as React and Next.js, ESYS 3.0 is characterized by high performance and responsiveness. Our knowledge in this field allowed for the creation of a dynamic user interface and ensuring quick access to system data and functions. This translates into a significant improvement in work efficiency and better user experiences. To learn more about Next.js technology, go to our separate blog post.
