A Spring Boot 3 RESTful API for managing departments and employees. Features include CRUD operations, Excel/PDF reporting with JasperReport, async email sending with Thymeleaf, Dockerized PostgreSQL, and database migrations with Flyway. Enhanced with Swagger documentation, and tested using JUnit 5, Mockito, and Testcontainers.

Backend - PetConnect

The goal of this project is to play with HTTPS and enable it in Spring Boot applications. For it, we will implement a Spring Boot Rest API that will have its endpoints ready to accept and server over HTTPS. Furthermore, a Spring Boot Shell Java application and a Frontend React application will be implemented to consume movies-api.

Knife4j is a set of Swagger2 and OpenAPI3 All-in-one enhancement solution

Goals: 1) Create a simple Spring Boot application to manage users; 2) Explore the utilities and annotations that Spring Boot provides for testing; 3) Test using Testcontainers.

Playground for devops, TDD, Gradle, Cucumber ++

Simple CRUD application with unity tests, integration tests and Spring Security+JWT

The goal of this project is to study the JPA relationships: one-to-one, one-to-many / many-to-one, and many-to-many.

Library for OpenAPI 3 with spring-boot

The goal of this project is to explore GraphQL. For it, we will implement two microservices: author-book-api and book-review-api.

The goal of this project is to implement an application called movie-app to manage movies. For it, we will implement a back-end Spring Boot application called movie-api and a font-end React application called movie-ui. Besides, we will use OAuth2 (Social Login) to secure both applications.

The goal of this project is to implement an application called order-app to manage orders. For it, we will implement a back-end Spring Boot application called order-api and a font-end React application called order-ui. Besides, we will use JWT Authentication to secure both applications.

The goal of this project is to implement an application called book-app to manage books. For it, we will implement a back-end Spring Boot application called book-api and a font-end React application called book-ui. Besides, we will use Basic Authentication to secure both applications.

The goal of this project is to explore how caching works. To achieve this, we will implement a simple Spring Boot application called "restaurant-api." We will use Neo4j for storage and select one of the following solutions (Simple, Caffeine, or Redis) for caching.

The goal of this project is to study JPA Batch Processing (i.e, insert / update / delete a set of records in a single command), JPA Locking and Datetime in JPA.

The goal of this project is to implement an application called product-app. It consists of two Spring Boot services: product-api (backend) and product-ui (frontend). Data will be stored in Elasticsearch

The goal of this project is to implement two Spring Boot applications: bitcoin-api and bitcoin-client. The bitcoin-api application simulates BTC price changes, while the bitcoin-client application listens to these changes and updates a real-time UI. The bitcoin-client UI is secured using Basic Authentication.

Project goal: Explore Kafka, Kafka Connect, and Kafka Streams. Components: store-api: Inserts/updates MySQL records. Source Connectors: Monitor MySQL changes, push messages to Kafka. Sink Connectors: Listen to Kafka, insert/update Elasticsearch docs. store-streams: Listens to Kafka, processes with Kafka Streams, pushes new messages to Kafka.

The goal of this project is to secure movies-app using Keycloak (with PKCE). movies-app consists of two applications: one is a Spring Boot Rest API called movies-api and another is a React application called movies-ui.

The goal of this project is to create a simple Spring Boot REST API, called simple-service, and secure it with Keycloak. Furthermore, the API users will be loaded into Keycloak from OpenLDAP server.
