This case study delves into a collaboration between Reiz Tech and a leading Lithuanian energy company. The project focused on optimizing user experiences, enhancing functionality, and ensuring seamless customer interactions.

Project Overview

With a legacy spanning two decades, the client's energy platform had evolved into a complex ecosystem. It featured two distinct self-service portals catering to residential and business customers.

These portals enabled customers to manage accounts, access critical data, and facilitate transactions. However, old technology, sluggish processes, and an imminent system replacement posed substantial challenges.


The client's aging system faced a twofold challenge. Firstly, the client's impending adoption of a new system raised concerns about the relevance and longevity of the existing platform.

Secondly, the technical stagnation of the system, reliant on outdated technologies like Visual Basic 6, .NET Core, and PHP 6, hindered agility and responsiveness. The absence of a streamlined development process, integrative testing, and limited data extraction capabilities further compounded the hurdles.


We implemented a multifaceted solution that addressed both technical and strategic challenges. A cross-functional team, including developers, business analysts, and quality assurance experts, collaborated closely.

The establishment of a well-defined product owner-client interface accelerated decision-making. Leveraging modern technologies, the team embarked on a gradual modernization journey, embracing .NET Core for enhanced stability and flexibility. Regular sprints with controlled feature installations replaced the traditional bi-weekly cycles.


Despite the project's short-term focus, the impact was far-reaching. The revitalized self-service portals now offered quicker response times, improved data accessibility, and seamless integrations with auxiliary systems.

Enhanced user interfaces and navigational structures reduced customer learning curves, leading to increased self-service adoption. The system's reliability remained sterling, and collaborative efforts ensured that critical bug reports were scarce and resolved swiftly.
