It was a pivotal moment for a large electronics retailer in Eastern Europe. They had an ambitious goal - to expand their business to the online marketplace and reach more customers. But there was a problem: their current website was outdated and unable to meet the growing demand. The online store suffered from poor user experience and slow performance, hindering sales and leaving them at risk of falling behind their competitors. Feeling the pressure to act fast, they turned to Modsen, a custom software development company with a proven track record of delivering successful e-commerce projects. The stakes were high, but Modsen was up for the challenge. With a dedicated team of engineers and a thorough understanding of the retailer’s needs, they set out to develop a custom e-commerce site that could handle a wide range of products, from electronics to home appliances, furniture, clothing, and more.


The client had complex requirements, and Modsen eagerly embraced the opportunity to tackle the development. The team knew that their expertise in building e-commerce sites could make a significant impact on the retailer’s business. The project was time-sensitive, and Modsen had to work within a tight deadline to deliver a fully-functional e-commerce site that met the client’s expectations.

Behind the scenes: Our Approach to
E-Commerce Development

The development process of the e-commerce site was a meticulous one, as Modsen followed a tried and tested custom software development approach. The project was split into several steps, starting from the initiation of the project and culminating in the closing stage. Each phase contained its specific objectives and tasks to accomplish, ensuring a seamless development process. Here’s a rundown of some of the major steps taken by Modsen when developing an online shopping platform for electronics retailer.

1 Initiation

To kick off the project, Modsen formed a dedicated team consisting of a project manager, a business analyst, a UI/UX designer, software engineers, and QA testers. They carefully analysed the project requirements, set up communication channels, and established clear deadlines and budget constraints to enable a smooth and effective workflow.

2 Discovery

As the project moved into the discovery phase, Modsen engaged in a deep exploration of the client’s business, delving into the intricacies of their operations, their target audience, and the competitive landscape. The team conducted extensive market research, including analysis of consumer trends, online user behavior, and competitor sites. They also visited some of the client’s brick-and-mortar electronics stores to gain a firsthand understanding of the customer experience and identify areas for improvement. In addition, Modsen facilitated several collaborative workshops with the client to clarify business requirements, define user personas, and establish key performance indicators (KPIs) for the new e-commerce website. The designers presented quick sketches and mockups to explore different design concepts and get early feedback from stakeholders. The team used this information to create a detailed product backlog and roadmap, outlining the development milestones and timelines. Through this process, Modsen was able to ensure that the new electronic retail shopping platform would meet the client’s needs and deliver a superior customer experience.
