Dublin, Ireland
My name is Juarez Barbosa Junior, and I have over 28 years of professional experience in Software Engineering and Developer Relations.
I am a Sr. Principal Java Developer Evangelist and Director of Developer Evangelism at Oracle. Previously, I was an Azure Developer Relations Lead – Director of Developer Relations at Microsoft. In addition to that, I was a Principal Developer Advocate, Developer Advocacy Director at Oracle EMEA, and a Thought Leader and Technical Evangelist at IBM.
From a technical standpoint, I am an expert in Java language, JDK, and JVMs (Java Virtual Machines). I have extensive experience and knowledge in Cloud Computing (Oracle OCI, Azure, GCP, IBM Cloud, and AWS), DevOps, Infrastructure as Code (IaC), Continuous Integration / Delivery (CI/CD), and Cloud Native. Also, I am a polyglot Software Engineer with experience in Java, Kotlin, Golang, Python, C, C++, and Javascript, and lately, I have been learning Rust.
Feel free to invite me to speak about Java, Microservices, Software Architecture, Solutions Architecture, DevOps, Cloud Computing (Oracle Cloud, Azure, AWS, GCP, IBM Cloud), Emerging Technologies (IoT, AI, Blockchain, XR), and Cybersecurity.

Area of Expertise
Topics
Revolutionize Java Database App Development with Reactive Streams and Virtual Threads.
With the advent of Reactive Programming and Virtual Threads, Java developers can scale Java database access using either option.
Using synchronous and asynchronous code, developers will learn to take their Java database applications to the next level, using either Reactive Relational Database Connectivity (R2DBC), Reactive Streams Ingestion (RSI), or JDBC with Virtual Threads.
This session explores how they can make the right choice per their specific requirements, focusing on performance, scalability, and simplicity.
Scale Java and Java Database Connectivity (JDBC) applications using either Reactive Relational Database Connectivity (R2DBC), the Reactive Streams Ingestion Library (RSI), or JDBC with Virtual Threads. Understand the R2DBC and RSI APIs, and how to use JDBC with Java Virtual Threads (Project Loom).
