CURIOUS
BY NATURE.
HANDS ON.

HI, I’M JOÃO. ↗

I like figuring out how things work — then finding out what I can make with them.

Electronics, automation and code are where I explore that curiosity. Sometimes through a circuit. Sometimes through an AI agent, a virtual machine or a project still taking shape.

Work, experiments and a reason to keep going. That’s what you’ll find here.

The portfolio is taking shape. All four project stories are still under construction.
Images and readings illustrate the concepts.

THE NEXT
STEP.

There’s always another question.
Another test. Another connection.

01

Agents for real-world tasks

Giving AI context and connecting it to everyday processes.

EXPLORING↗
02

The weather station

Fine-tuning sensors and keeping an eye on the environment.

EXPERIMENTING↗
03

Less repetitive work

From openings and dimensions to correctly sized blocks in a DWG.

OFF THE
CIRCUIT.

Running, trails and new places.
Sometimes the best way forward
is to step outside.

One step at a time.

Discipline, consistency and a desire to go further. Running shapes the way I approach a project.

SIGNAL DETECTED / 01

From physical to digital.

A sensor reads the environment. Code interprets the signal. An action makes a difference.
