Keeping up with business needs

with a bold, consumer-focused mission: to deliver orders within minutes at supermarket prices. It is possible due to the smooth cooperation of multiple applications addressing each step of the delivery process, including mobile apps for the end-users and the e-commerce system, for riders, pickers, and the ERP system.

Their offer is composed of a series of connected apps for different user types, such as customers, riders, and warehouse workers. Flink structures teams narrowly around each app or even specific features. It’s a dynamic setup where staff might be relocated often, to the benefit of efficient implementation.

The QAs worked on both the backend and the frontend, providing everything from ad hoc regression to smoke testing, and ensuring the migration would happen without a hitch.

Beyond migration, Monterail worked on multiple features across the ecosystem. Some highlights include a desktop webshop, checkout and payment functionalities, order location tracking and post-order user experience, user authentication, and authorization.

The scope also included systems for back-office operations, covering a warehouse employees app, a dashboard for managing specific orders, and inventory management.

Data migration was an especially interesting challenge. We developed a custom API to transfer data from Saleor to Commerce Tools, affecting several applications in the ecosystem. All under the hood, so end users don’t feel any change.

Along the journey, we helped strategically break down monoliths, such as the checkout and cart systems, into microservices. This separation ensured not only scalability but also work efficiency, as now different developers can contribute more closely with less risk of conflict.

1. Quick and precise initial code review in Go

2. Monterail team grew from two to 11 following business needs

3. Pro-active and smooth communication across the board

The team, consisting of even up to eleven developers and QA engineers, joined different Flink rockets which enabled fast-paced development and accommodating the dynamic needs of the project. The partnership gave Flink access to a valuable and flexible pool of first-rate Go developers, QA engineers, and other specialists in a core stage of fast expansion.

With this solid foundation built, our partner is able to more easily include features and scale their efforts across different locations. For example, adding a warehouse to the system began as a complex technical task and now doesn’t require an engineer. It’s easier to add cities and even countries, leaving no roadblocks for accelerated growth.

• The apps enjoy scalable growth due to Go expertise

• Flink had access to developers as soon as the business needed them

• Different teams have an easy time connecting and integrating
