Introduction

This case study looks at the software development efforts of a major fast-food chain serving thousands of restaurants around the world. With several locations and development centers employing over 150 people, the company worked to improve its e-commerce remote ordering system. Over a span of 15 years, they used .NET C#, microservices, and agile methods to make operations more efficient and enhance the customer experience.

The Story

The company began its software development journey with the goal of overhauling its e-commerce remote ordering system. To support this, the team set out to build a cloud-based microservice architecture with a strong and scalable backend. The new setup was designed to handle high-availability scenarios and meet growing demand, with the capacity to process hundreds of thousands of orders per second.

The Challenge

The development team faced several major challenges throughout the project. One was managing the shift in architectural models, moving from a monolithic setup to a microservices-based structure. Each transition had to be carefully planned and executed to avoid service disruptions and maintain continuity.

Another key challenge was integrating with multiple payment providers. The team needed to build secure and reliable systems for handling transactions while ensuring compatibility with a range of payment platforms. On top of that, adding advanced features like ordering, loyalty programs, and personalized offers required a deep understanding of customer behavior and preferences.

The Results

Despite the many challenges, the company’s software development efforts delivered strong results. Moving to a microservices architecture improved system speed and responsiveness, which helped boost customer satisfaction. By using agile methods and modern technologies, the team shortened deployment times, allowing for quicker updates and ongoing improvements. Advanced features like ordering, loyalty programs, and personalized offers were successfully implemented, strengthening customer engagement and loyalty.
