I help engineering leaders build teams that come together across distance.

Distance is geography. Density is design. Through my book The Invisible Distance, the PreVetted Podcast, and a decade-long partnership practice at Density Labs.

I shipped my first line of production code at fifteen.

Running my own startup with coaches from Microsoft in Buenos Aires. The dot-com bubble burst, an acquisition fell through, and Microsoft hired me at sixteen. By the time I was sitting in conference rooms demoing software to executives at one of Argentina's largest telecoms, I had already built and lost a company.

What I learned at Microsoft shaped everything after. At sixteen you cannot rely on authority, you do not have any. What you have is what you actually know and whether you have done the work to be useful in the room. I learned to project power without authority, to push back on hierarchy when the idea was better, and to treat a work culture where deadlines are real and credit is tracked as a privilege, not a constraint.

"Twenty years later, those same lessons run through how I run Density Labs."

An engineering partnership firm that connects US companies with senior engineers in Latin America. Most staffing relationships last 18 months. Ours have lasted more than a decade. That is not an accident. It is the result of thousands of small decisions about how to integrate teams, build trust across borders, and treat partnerships as long-term commitments instead of transactions.

I wrote The Invisible Distance because after 150 conversations on my podcast with engineering leaders across the industry, the same question kept surfacing without people realizing they were asking it: how do you build a team that comes together across distance and still feels like one?

The book is my attempt to draw a map from the terrain itself, not a framework imposed from outside. If you are a VP of Engineering, a Director, or anyone responsible for making distributed teams actually work, this work is for you.

What I'm working on

Three projects, one thesis: distance is a design problem.

The book is such an amazing read. I've already reached chapter 10 and can't put it down. Your storytelling is not only exceptional but also authentic. I connected with every character as if I knew them personally.

A Field Manual

The
Invisible
Distance

Why cross-border engineering teams fail, and the system that makes them win.

The Book · Q3 2026

A field manual for engineering leaders running teams across borders.

Not a remote work book. Not an outsourcing book. The system underneath both.

What's inside
01 The Correction Clock A cost most teams misprice
02 The Iceberg Inventory Hidden risks under every distributed team
03 The Belonging Window Why the first 90 days decide retention
04 The Visibility Stack The framework that explains why people leave
05 The Density Method An operating system for cross-border teams

Conversations with people who actually build the teams.

Founders, engineers, and operators on building durable companies and shipping things that last. Long-form interviews, no fluff, no thought leadership theater.

The newsletter

Field notes from the invisible distance.

Once or twice a month. What I'm seeing in cross-border teams, AI engineering, founder-led companies, and the strange physics of building software with people you've never met in person.

No promotion. No "10 things I learned this week." Just the things worth writing down.

Where you are in the conversation.

If you're a Director or VP of Engineering reading this, there's a chance the work I do can be useful to you. Pick the level that matches where you are right now. Most people start at the top and move down only if they need to.
