Lucas Yohan Sousa de Alencar
Resumo
I'm a Software Engineer with 2 years of professional experience focused on the Java ecosystem.
My core stack is Java, Spring Boot, PostgreSQL, Docker and AWS. I'm currently expanding to the frontend with React to become a more complete Full-Stack Engineer.
So far, I've built and shipped a REST API and a microservice in Java, with a focus on clean code, scalable architecture and performance.
Currently working as an IT Analyst, where I gained strong experience in the banking domain, system analysis and working in large-scale enterprise environments. Now I'm looking to return full-time to hands-on engineering as a Java Developer.
I'm looking for international opportunities where I can grow as a Java Backend / Full-Stack Engineer building scalable products.
Let's connect if you're working with Java, Spring Boot, and distributed systems.
