We cut AWS S3 costs by 40% overnight.
🔪We cut AWS S3 costs by 40% overnight. The storage wasn’t the problem. A lot of companies assume their AWS bill is driven by infrastructure size. In reality, it’s often driven by behavior. In this case: very small storage footprint no heavy traffic nothing “obviously expensive” Yet the bill kept growing. After digging in: ~85% […]
After 20 years in Argentina, we moved to the US.

After 20 years in Argentina, we moved to the US. My life fit into 2 large suitcases. My son needed 2 more. My wife and baby… about 12 😄 But the idea stayed the same. Growing up, my dad always pushed one thing: keep things lean Less stuff Less weight Less dependency That mindset stayed […]
I just got off a call where someone told me:

I just got off a call where someone told me: their clients don’t understand agile don’t know how to scale their code struggle to even debug properly A few years ago, this would sound absurd. Today, it’s becoming normal. We spent years worrying about technical debt. Now we’re entering a world of cognitive debt. AI […]
I audited a platform last week.

I audited a platform last week. Found a system built 25 years ago. Still running. Still processing real transactions. Real money. Nobody on the current team fully understands how it works. Nobody knows why it was built the way it was. And nobody has ever asked whether it still needs to exist. But it costs […]
Give me six hours to chop down a tree and I will spend the first four sharpening the axe.”
“Give me six hours to chop down a tree and I will spend the first four sharpening the axe.” — Abraham Lincoln My friend does remodeling and construction work. I asked him once what the biggest lesson he’d learned in his line of work was. “90% of the job is using the right tool for […]
Outsourcing and staffing as we knew them are dead.
Outsourcing and staffing as we knew them are dead. Over the last year I ran technology audits across several companies. When I got to the people layer, the numbers were hard to ignore: (downsizing/rightsizing) Company A: 20 engineers → 5 Company B: 17 engineers → 2 Company C: 17 engineers → 5 Same output. In […]
AI-Era Problem, Pre-AI Solution

AI-Era Problem, Pre-AI Solution A CEO called me a few weeks ago. His SaaS platform was a mess. He needed help sorting it out and preparing for scale. Normal enough. Then I asked about the team. 50 people in R&D. That number alone told me most of what I needed to know. In 2026, a […]
Last week we ran an AI training day for developers.

Last week we ran an AI training day for developers. 40 people. 3 hours. One topic: how to actually use AI to ship faster. Not ChatGPT for answering questions. Not copy-pasting code from a browser tab. Real AI-assisted development. Terminal-level. Codebase-aware. Production-ready. We showed two real products built with this approach: SaaS product A: data […]
The less it costs to build, the more it costs to build the wrong thing.

The less it costs to build, the more it costs to build the wrong thing. Everyone is talking about AI replacing engineers. Some of that is true. Junior and mid-level execution work is getting squeezed. Fast. But there’s a layer nobody is talking about. Senior technical judgment is getting more valuable. Not less. Here’s why. […]
You can’t out-token bad modeling !

You can’t out-token bad modeling ! History keeps repeating itself in data. And nobody seems to notice. 1996. Ralph Kimball publishes The Data Warehouse Toolkit. Structured data. Star schemas. Dimensional modeling. Clean, disciplined, expensive to build, but when it worked, it worked. Early 2000s. NoSQL arrives. MongoDB, Cassandra, CouchDB. “Relational databases are too rigid. Structure […]
