I'm Lucas Souza de Oliveira, a frontend developer from Telêmaco Borba, Brazil. My path in software started in 2018, when I enrolled in Systems Analysis and Development at the Federal Institute of Paraná.

Since then I've worked remotely for companies in the United States and Chile, building systems for Brazil's Federal Public Defender's Office, an in-house fleet monitoring platform for a logistics company, and multi-tenant SaaS products.

I care about interfaces that are fast, accessible and easy to maintain, and about the architecture that keeps them that way.
