Profile

Lucas Barbosa during an outdoor trip

I care about understanding the problem before writing the solution.

I hold a Programming Technician degree from Universidad Tecnológica Nacional and I am currently studying Computer Engineering at UADE. My background combines Node.js, React, .NET, and hands-on experience with both new and production systems.

I enjoy working in cross-functional teams, supporting the professional growth of the people around me, and encouraging the adoption of emerging technologies. I aim to turn that learning into software solutions that create value without losing sight of their everyday impact.
