ORCID Open Source Project

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 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. Additionally, 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 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.

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 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 implement a "News" processing pipeline composed of five Spring Boot applications: producer-api, categorizer-service, collector-service, publisher-api and news-client.

Experiment with Kafka, Debezium, and ksqlDB. research-service: Performs MySQL record manipulation. Source Connectors: Monitor MySQL changes, push messages to Kafka. Sink Connectors and kafka-research-consumer: Listen to Kafka, insert/update Elasticsearch. ksqlDB-Server: Listens to Kafka, performs joins, and pushes new messages to new Kafka topics.

The goal of this project is to implement a Spring Boot application, called movies-api, and use Filebeat & ELK Stack (Elasticsearch, Logstash and Kibana) to collect and visualize application's logs and Prometheus & Grafana to monitor application's metrics.

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.

Spring Boot 3 Rest API example that implements CRUD operations - GET / POST / PUT / DELETE and filter requests

In this project, we will implement two Spring Boot Java Web application called streamer-data-jpa and streamer-data-r2dbc. They both will fetch 1 million of customer records from MySQL and stream them to Kafka. The main goal is to compare the application's performance and resource utilization.

Goal: create a Spring Boot app called book-service accessible only through the Kong API gateway. In Kong, the kong-oidc plugin will be installed, enabling communication between Kong and Keycloak. This setup ensures that when Kong receives a request for book-service, it validates the request in conjunction with Keycloak to ensure its authenticity.

The goals of this project are to: 1) Create a Spring Boot application that manages books, called book-service; 2) Use Keycloak as OpenID Connect provider; 3) Test using Testcontainers; 4) Explore the utilities and annotations that Spring Boot provides for testing applications.

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

The goal of this project is to create a simple Spring Boot REST API, named 'simple-service,' and secure it using the Spring Security LDAP module. Additionally, Testcontainers will be utilized for integration testing.

Spring Web MVC + JPA + Hibernate + JSP + JSTL application

The goal is to explore Axon. We will develop a food-ordering app comprising 3 Spring Boot applications: customer-service, restaurant-service, and food-ordering-service. These services are implemented with CQRS and Event Sourcing, utilizing the Axon Framework. They connect to axon-server, which serves as the Event Store and Message Routing solution.

A step-to-step migration from JavaConfig to functional

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

Goal: create a Spring Boot application that handles users using Event Sourcing. So, whenever a user is created, updated, or deleted, an event informing this change is sent to Kafka. Also, we will implement another application that listens to those events and saves them in Cassandra. Finally, we will use Testcontainers for end-to-end testing.

The goal of this project is to explore the capabilities of Vault. To achieve this, we will develop applications that utilize Vault to store and retrieve secrets. Vault dynamically generates credentials for accessing databases and relies on Consul as the backend. The authentication method employed in Vault is AppRole.

In this project, we will use LocalStack to locally simulate some services provided by AWS Cloud such as: DynamoDB, Lambda, SNS and SQS. Additionally, to simplify the use of AWS managed services, we will use Spring Cloud AWS.

The goal of this project is to use Nginx as a reverse proxy and load balancer for a Keycloak cluster with two instances and a Spring Boot application, called simple-service, also with two instances. The simple-service app will use Keycloak for IAM.

The goal of this project is to create a Spring Boot application called movies-app that allows users to log in using Username/Password Authentication and One-Time Token Login
