A circular tech services provider on a path to boost its core system

The client is Europe’s leading provider of circular tech services to enterprises, public entities, and the recommerce industry. Driven by the ambitious goal to support a more sustainable lifecycle of ICT equipment without impacting profitability, the client offers comprehensive electronic management services, as well as recovery and remarketing services.

The client’s unique business model is gaining traction. With 6,500 points of sale and 800+ wholesalers and retailers, the circular tech company now handles over 1.6 million devices annually. To further enhance its market-leading offering and meet the needs of the growing customer base, the client was looking to augment its in-house team with mature .NET development talent.

Diving deep into the platform complexity

Finding a candidate who is the right technical and cultural fit can be tricky. When looking for relevant skills and experience, the client interviewed a number of developers from different outsourcing companies before ultimately handpicking Symfa’s .NET engineer who quickly joined the team.

The major challenge was the scale and complexity of the solution. The client’s core .NET-based system that streamlines the process of buying used devices relied on the layers of entangled business logic and custom rules, requiring a new team member to take a deep dive into workflows and processes.

Advancing the platform with new features and optimized performance

Symfa’s .NET engineer was part of the team that worked on new functionality development and overall enhancement of the core buyback platform. The easy-to-use white-label platform is designed to make the entire process simple and transparent through automated price evaluation based on numerous parameters.

As an integral part of the client’s in-house team, Symfa’s .NET talent was working to drive the core buyback system forward. Over the year, the augmented team helped a leading provider of IT lifecycle management services enhance the platform with new features, fix bugs, and optimize performance. Happy with the mature expertise, seamless communication and speed of delivery, the client continues collaboration with Symfa while moving to enable circular economy at scale.
