Welcome! πŸ‘‹

I'm a Software Engineer and Open Source Contributor from Rio de Janeiro.

>> Open Source Contributions <<

Here's some of what I've had the opportunity of contributing so far.

πŸƒ Spring Cloud AWS SQS Lead and Maintainer

String projectName = "Spring Cloud AWS";
String projectDescription = "The project aims to simplify " 
        + "integrating Spring applications with AWS services.";
String myContribution = "I've had the opportunity to rewrite "
        + "the SQS integration from the ground up. Now I'm the SQS Lead and project maintainer. ";
Integer linesOfCodeAndDocsCommited = 30_000; 

@see Spring Cloud AWS SQS Integration Documentation πŸ“š

πŸƒ Spring for Apache Kafka

String projectName = "Spring for Apache Kafka";
String projectDescription = "The project brings familiar Spring " 
        + " abstractions to Apache Kafka.";
String myContribution = "I've had the opportunity to contribute the "
        + NonBlockingDelayedRetries.class + " feature.";
Integer linesOfCodeAndDocsCommited = 20_000; 

@see Spring Kafka Documentation for the Non-Blocking Retries feature πŸ“š

I've worked closely with the project's team on this feature, interacting with users on Github Issues and Stack Overflow, reviewing feature-related PRs, adding new functionalities, and so on.

Spring Kafka documentation

Apache Pulsar Messaging Framework

Parallel Kafka Consumer Messaging Framework

String projectNameOne = "Apache Pulsar Messaging Framework";
String projectNameTwo = "Parallel Kafka Consumer Messaging Framework";
String projectDescription = "The projects aim to simplify integrating with Apache Pulsar "
        + "and Parallel Kafka Consumer"

The SQS integration I created for the Spring Cloud AWS SQS project is actually a meta-messaging-framework, and I've created the Apache Pulsar Messaging Framework and Parallel Kafka Consumer Messaging Framework projects out of it.

Those are powerful, high-throughput solutions, non-blocking solutions.

These projects have zero dependencies to AWS SDK, and have approximately 35 and 15 classes respectively.

πŸƒ Load Test App for Spring Cloud AWS

String projectName = "Personal project for Spring Cloud AWS SQS load tests";
String projectDescription = "Project to perform simple load tests " 
        + "with the SQS Integration on AWS ECS.";
String projectInfrastructure = "This app features " + Terraform.class
        + " and " + GitHubActions.class + " CI / CD pipeline for deployment on ECS.";

Results so far with a single ECS instance and up to 1M messages show up to:

* **17K** messages / second with 4 vcpu and 8 GB memory
* **8K** messages / second with 2 vcpu and 4GB memory
* **4K** messages / second with 1 vcpu and 2GB memory

Check the app repo out and perform some tests of your own!


πŸƒ Stack Overflow

String projectName = "StackOverflow";
String myContribution = "I've been answering questions about the "
        + NonBlockingDelayedRetries.class + " feature and general distributed ";
        + "systems questions around Kafka and Spring Kafka.";
Integer reputation = 2_000;
