The objective

The main objective was to implement a microservices architecture that would guarantee development speed, performance, reliability and security. Initially, the app development was started as a Spring-based monolith, but this approach proved to be unsuitable and the transition to microservices became necessary in order to meet the market's growing demands for growth and innovation.

The start-up began with an external development team, but lacked the in-house technical expertise to fully understand the work and faced delays in promised releases. The core architecture, on the API side, was initially based on a Spring-based monolith, which made it difficult to manage and evolve the system.

Development side, the following were carried out:

  1. Redesign of the API architecture: the first initiative was the transformation of the architecture from a monolith in Spring to microservices using Nest.js. This approach would have improved the modularity, scalability and maintainability of the system. 
  2. Evaluation of developers' skills: an in-depth analysis of developers' skills was performed to understand the technical decisions made. This allowed the team to adapt to the new technological requirements and ensure a smooth transition. 
  3. Team change: the need to adapt to new technologies brought about a change in the team, with a focus on developers with specific skills on Nest.js, PostgreSQL, Rabbit MQ, Flutter and Angular.
  4. Implementation of specific technologies: 10 Nest.js microservices were implemented, using five PostgreSQL databases and a Rabbit MQ broker. In addition, two mobile apps were developed in Flutter and two web apps in Angular to ensure a cohesive user experience across different platforms.
  5. Iterative development management: Iterative development management was adopted via sprints, ensuring continuous monitoring and improvement, as well as adherence to deadlines and product quality.

To meet the challenges of growth and innovation, Move implemented a set of advanced technologies that improved system architecture and operations. The technologies used were:

  • Nest.js to create modular and scalable microservices, improving maintainability and speed of development.
  • PostgreSQL as a relational database to ensure efficient and secure data management, distributed over multiple instances for greater reliability.
  • Rabbit MQ implemented as a broker for message management and to facilitate communication between the various microservices.
  • Flutter to develop the mobile applications, providing a consistent, high-performance user experience across different platforms.
  • Angular to build the web applications, ensuring a robust structure and a responsive, modern user interface.
