Portrait of João Pedro Braz

Backend · Java & Spring · Full-stack

Open to workAlmada, PortugalFrom São Paulo

I build the part of the product nobody photographs: data models, APIs, and the unglamorous plumbing that keeps an app from quietly falling over at 3am.

Born in São Paulo, based in Almada. I came up through multimedia and web design, so I can take a project from a tidy interface all the way down to the database without losing the plot.

Java and Spring are home turf. PostgreSQL and Docker keep me company most days, and I get a little friendlier with React and Next.js every week.

Safety Manager

Full-stack safety platform

Tracks workplace incidents, equipment and compliance. Server-rendered and boxed up in Docker so deploys stay boring.

    Proudest moments

    Not a job list — the things that were hard at the time.

    2025

    Finished my degree at 17/20

    I started that course as a designer who could barely write a for-loop. I finished it writing the backend for my own project.

    17/20Final grade

    2025

    Put a Next.js app into production

    First time my code had users who never met me and couldn't ask what a 500 meant. It had to just work.

    2026

    Got paid to write code

    The moment this stopped being a hobby. Someone weighed my work against their money and chose it.

    01First client

    2024

    Wrote printf() from scratch

    No standard-library shortcuts — every format specifier and every allocation done by hand. Clean code and memory management were the whole point.
