Welcome to DOIS

We've been building software for a long time. Between the two of us, we've seen startups implode, enterprises ossify, and hype cycles come and go. We've shipped products across continents, led teams through chaos, and learned — sometimes the hard way — what actually works.

Now we're writing about it.

Why Now?

Software is changing faster than most people realize. AI isn't just another tool in the belt — it's reshaping how we think about building, shipping, and maintaining systems. The engineers who figure this out first will have a massive advantage. The ones who don't will be left wondering what happened.

But here's the thing: most of what you're reading about AI and software development is wrong. Not maliciously wrong — just oversimplified, overhyped, or written by people who haven't actually shipped anything with these tools.

We have. And we have opinions.

What This Is

DOIS is where we share what we think — about AI, about engineering, about the craft of building things that work. Some of it will be practical. Some of it will be controversial. All of it will be honest.

We're not here to tell you what you want to hear. We're not going to hedge every opinion with "it depends" or pad our takes with qualifiers. If we think something is wrong, we'll say it. If we change our minds, we'll say that too.

This isn't for everyone. If you want feel-good content or gentle validation, look elsewhere. If you want safe, consensus-approved takes — there are plenty of newsletters for that.

But if you want to know what two engineers who've been in the trenches actually think? Stick around.

What We Believe

A few things we hold to be true (for now):

1. The mainstream narrative is usually off. Every hype cycle, the loudest voices get it wrong. The signal is in the margins.

2. Experience compounds, but only if you pay attention. We've seen patterns repeat. We try to learn from them.

3. Shipping beats theorizing. We're practitioners, not pundits. We build things, break things, and ship things.

4. Strong convictions, loosely held. We have opinions. We're not precious about them. Show us better evidence, we'll update.

The Name

"Dois" means "two" in Portuguese. Two people, two perspectives — one from the startup world, one from the enterprise trenches. Different contexts, same commitment to building things that work.

We think the best ideas come from tension between perspectives. That's what this is.

What's Next

We'll be writing about:

• What's actually working with AI in real engineering contexts (not the demos)
• Patterns we've seen repeat across companies and decades
• Unpopular opinions about tools, practices, and industry trends
• The craft of shipping software in a world that's changing fast

Some of it will resonate. Some of it you'll disagree with. Good. That's the point.

Welcome to DOIS. Let's see where this goes.
