I write about what I learn while building.

I'm Tulio. I've been building digital products for more than a decade: some worked, others turned into essays. I created DevPleno, a Brazilian YouTube channel about programming, careers and building products. Here I document the behind-the-scenes: the decisions, the mistakes and the process, not just the outcome.

I believe building in public is strategy, not vanity. And that clarity (writing in a way that never needs a second explanation) is the most underrated skill a maker can have.

No hype, no success formula. Just what you can learn by looking at the work up close.
