“I WRITE CODE THE WAY
YOU WRITE A LETTER: SLOWLY,
UNHURRIED, WITH PURPOSE.”

It all started on a rainy morning, when the family computer froze for the third time in a row. Right then, somewhere between the restart and the smell of my mother’s fresh coffee, I realized I didn’t want to be a user anymore. I wanted to understand what was on the other side of that blinking cursor.

That’s what I’d say if this were an adventure novel or a biopic. The truth is a little less romantic: I was 16 and repeating my first year of high school — talented by nature, lazy by vocation. So I decided that either I hit the books, or I embraced a future of working under the blazing noon sun on a construction site. The computer was the most interesting distraction I had at hand, and that’s how I ended up falling in love with software.

I work with distributed systems, infrastructure as code, and the stubbornness to reject any abstraction I can’t explain to a colleague in three minutes. I believe every good software architecture is, above all, a good decision about what not to do. It took a lot of wrong decisions to conclude that less is more, and that the best line of code is the one you don’t write.

This paper is my portfolio — but it’s also a personal manifesto. In here you’ll find the projects I’m proud of, the articles I write when I have the time and the itch, and a classified ad asking you to get in touch, if this conversation makes sense to you too.

Enjoy the read.

“ENGINEERING
IS WHAT’S LEFT when the hype is gone”

ILLUSTRATION FOR THE ARTICLE · STAFF / SP

By 2026, software has already been through three fads and two identity crises — and I went along for the ride. Every wave brings its prophets and their certainties: “now it’s serverless”, “now it’s AI”, “now it’s all Rust”. And every wave repeats the same pattern: the first companies adopt, the ones in the middle suffer, and the last ones arrive when the early adopters are already back on whatever worked before.

Deep down, software engineering is a profession of brave skeptics. You have to be curious enough to try everything and skeptical enough to fully believe nothing. That fine balance is what makes a good engineer — not the stack they master, nor when they started making money from code.

Spend seven years writing code and you start to notice that productivity doesn’t come from tools. It comes from the discipline of not adding complexity that isn’t justified by real, measurable pain... I still slip on that, but only those who work make mistakes.
