In this project, I worked in a team of developers to build and maintain a sale and post-sale system of telephone lines that is currently operating nationwide on Digitel servers. As a Backend developer, my responsibilities included: • Designing and implementing the system architecture, including the database and business logic. • Collaborating with other Frontend developers to integrate the user interface with the Backend logic. • Ensuring the scalability, security, and performance of the system. • Maintaining and updating the system in production, fixing bugs and improving performance. • Researching and adopting new technologies and tools to improve development and efficiency. In general, this experience provided me with a solid understanding of Backend architecture and best development practices, as well as the ability to collaborate effectively with other developers to deliver a high-quality product.

In this project, I worked in a team of developers to build and maintain a sale and post-sale system of telephone lines that is currently operating nationwide on Digitel servers. As a Backend developer, my responsibilities included: • Designing and building the system architecture, including the database and ER diagram. Implementing system logic using Java, Maven and Spring Boot. • Securing the system by implementing JWT for security. • Optimizing the system to be scalable and high-performing through cache implementation. • Incorporating internationalization (i18n) functionality to support multiple languages. • Dockerizing the entire system for ease of deployment and distribution. • Configuring and maintaining a Postgres database to handle the system's data needs. This experience allowed me to delve deeper into creating a REST API from start to finish and granted me a comprehensive practical understanding of various technologies and tools. I was able to apply a skillset that ranged from database design to security implementation and system performance optimization, all within the context of delivering robust user functionality.
