▪ Development of a new project▪ I designed the system architecture based on best practices from Spring and AWS, ensuring a modular and scalable structure. I implemented a microservices architecture to improve system maintainability and scalability.▪ I used several Spring modules: Spring Boot, MVC, JPA, Cloud.▪ AWS EC2 for the deployment of servers and cloud applications▪ I used relational database management systems such as Oracle, MySQL, and SQL Server. I used DDL and DML statements for database construction and content manipulation. I worked with DAO design patterns to access data and DTO to transfer objects between different users and computers, either locally or remotely.▪ Implementation of unit tests using JUnit and Mockito to ensure code quality and detect errors in early development stages. Test automation through the integration of unit tests into the continuous integration pipeline with Jenkins.

▪ Java development where I used various frameworks such as Hibernate as an ORM for object-relational mapping, Maven as a project manager▪ Spring Boot for accelerating web applications and Microservices through automatic configuration▪ Spring Data for accelerating repository access via an extension of class sets▪ Spring JDBC allowed me to quickly develop a persistence layer with a high level of abstraction over the relational model and the API used to interact with the relational database▪ Spring JPA to access the persistence layer with minimal effort, reducing repetitive code▪ Spring MVC to create applications based on the MVC model that generate simple HTML pages where I could easily load content.

▪ I was part of teams dedicated to designing, developing, and deploying APIs using Spring Boot as the technological foundation. My role ranged from conceptualizing and designing the application programming interface to implementing and optimizing the business logic behind the API.▪ To facilitate efficient API testing and development, I used tools such as Postman Canary. This platform allowed me to conduct thorough testing of the implemented functionalities, validate the integration of the APIs with other parts of the system, and ensure that requests and responses met the established requirements.▪ I worked under the Scrum methodology, participating in daily stand-ups and sprint reviews to enhance teamwork.
