Product engineer.
I turn problems into products people actually use.
I'm Esteban. I work across the whole product — talking to users, shaping the idea, designing the system, writing the code and shipping it. I care less about the stack and more about whether it made someone's life better.
I'm also an entrepreneur. I co-founded Damascuss, I've been out raising money, and I've learned a lot from other founders along the way. And I work for a company too — because I love building products, wherever they live.
Ten years in, from my own studio to Uber-scale backends. This site is where I think out loud.
What I believe
- 01
Technology has to improve a life. Engineering only makes sense when it solves something real. If it doesn't make some part of someone's day better, it's just noise — however clever it is.
- 02
Start with the problem. Code is the expensive part. I want to understand who hurts, why, and what "better" looks like before I open the editor.
- 03
Product and engineering are one craft. Splitting them was a mistake — like splitting frontend from backend, which we're now putting back together. Few people have built anything that mattered without thinking like engineers; even the best designers do.
- 04
Technical excellence by default. Quality isn't a phase or a nice-to-have. Reliable systems, thoughtful decisions and care for the details people actually feel are the starting point, not the upgrade.
- 05
Code got cheap. Quality got expensive. I love AI — it's the best tool I've had in my career. But now that generating code costs almost nothing, the scarce part is knowing what to build, what to keep and what is actually right. That's where I put my time.
- 06
Complexity on demand. Start with exactly what the problem needs and let it grow only when reality asks for it. Never build for a scale you imagine.
- 07
Theory, put into practice. Science explains; engineering applies. Theory matters, but it only becomes useful through making, breaking and trying again — until it comes naturally when the next problem shows up. Engineer shares a root with ingenious, not with a diploma.
- 08
Ship small, learn fast. A rough version in real hands beats a perfect one in a branch. Users are the best reviewers I have.
- 09
Own the outcome, not the ticket. Done is when it works for the person using it — not when the PR is merged.
- 10
Good products, good life. Products are one of the best ways I know to contribute: they improve other people's lives and pay for a good one of your own. I'm not cynical or hypocritical about it — money matters, and earning it with something useful is honest work.
- 11
Respect is earned, not titled. I respect professionals for the value they add and what they make happen — not for their title. Being the manager doesn't make you right; being useful does. I hold myself to the same rule.
