Hi there! 👋
I'm Natanael
I grew up watching Dexter's Lab and wondering how someone could build an entire secret laboratory. Turns out, you just become a software engineer.
12+ years later, I architect the kind of systems that power millions of interactions. Invisible infrastructure that has to work perfectly even when nobody is watching.
I am Brazilian, based in Melbourne, and I have spent my career at the intersection of scale and craft. I care deeply about code that is readable, systems that are maintainable, and teams that ship with confidence.
Currently expanding into cybersecurity because knowing how things break is the best way to build things that do not.
Let's connect!
