Innovation in cashless payments: the Move case study

In the digital evolution of cashless payments, companies must constantly innovate to remain competitive. Move, a start-up in the German digital payments industry, recently faced a significant challenge under our strategic guidance. The decision to move from a monolithic to a microservices-based architecture not only revolutionised Move's internal operations, but also strengthened its position in the competitive German digital payments market.

Challenges

Move faced several challenges in its journey of growth and technological innovation. Initially based on a Spring monolith, the company was faced with both complex management and significant rigidity in modifying and scaling the system to meet growing market and user needs. These challenges actually turned out to be opportunities to radically transform our client's technology architecture.

 

The importance of microservices in the digital context

Microservices have become an essential software development methodology for modern companies. They allow a complex application to be broken up into smaller, self-contained components, each of which manages a specific part of the application's functionality. For Move, the adoption of microservices has meant improving development speed, system reliability and facilitating the introduction of new functionality, all under the careful supervision of our CTO.

Key technologies

To achieve the objectives of transformation and improve operational efficiency, we adopted the following technologies:

Nest.js: Node.js framework chosen for its robustness and scalability in creating modular microservices.

PostgreSQL: relational database used to ensure secure and reliable management of customer data.

Rabbit MQ: messaging broker adopted to facilitate communication between different microservices, ensuring consistency and integrity of transactions.

Flutter and Angular: used for mobile and web application development respectively, providing a consistent user experience across different platforms.

 

Why Flutter for a mobile app

Choosing Flutter over other options was no accident. Here is a brief overview of the advantages of Flutter:

 

The central role of a CTO

Usually, the tasks of a CTO range from managing development teams, identifying the necessary tools and identifying the best strategy for the company's technology. Special attention should also be paid to the growing demand for a Fractional CTO, i.e. an external CTO who is not hired full time, but follows a company or project part time. Several advantages come with this role. First of all, a company brings a specialised expert in-house who can offer solid technological and organisational guidance and advice. Additionally, the reduced presence of the Fractional CTO saves on the costs of a full-time hire by adapting his or her presence to the needs of the moment. Finally, a Fractional CTO can be deployed for a specific period of time or on key projects, without committing to a long term. 

Under the guidance of our fractional CTO, Move successfully tackled the complex technological transformation. Not only did he support and guide the transition process from a monolithic to a microservices-based architecture, but he also played a key role in the initial analysis of the technological challenges and the implementation strategy of the new technologies.

Conclusion

Move's case study highlights the benefits of adopting microservices in the cashless payments industry. Not only has this transformation optimised system performance and scalability, but it has also given Move greater agility in developing and adapting to market needs. With microservices, the company has been able to improve the modularity of its system, implement new functionalities quickly, and maintain high maintainability, which is essential to support the growth and evolution of the business in the long term.

Central to this technological transformation was the competent guidance of our CTO, who directed the team through an effective microservices adoption strategy. This not only facilitated the implementation of advanced technologies such as Nest.js, PostgreSQL and Rabbit MQ, but also stimulated a collaborative and innovative development environment. Along with our highly skilled development team, the company was able to respond to technical challenges and emerging opportunities, thus consolidating Move's position in the digital payments industry.
