Currently based in Argentina I've spent 20 years designing data platforms that work — not just on day one, but when source schemas change, volumes spike, pipelines fail, and the engineer who built them has moved on. My background spans greenfield warehouse architecture, ETL and pipeline engineering, API integration, and Power BI reporting — delivered across government, enterprise, and startup environments in the US, UK, Japan, and New Zealand. I work from strategy through to execution: I can define what you need to build and then build it. Whether you need a single pipeline untangled or an entire data platform built from the ground up, I design and deliver solutions that are fit for purpose, scaled to where your now and your future. No unnecessary complexity no overengineered infrastructure you can't maintain. And if you're not using AI to write your code right now, you're wasting someone's time and money. The value isn't in the syntax — it's in the architecture, the standards, and the experience to know what breaks and why. If you want a data platform that's built to last, not just built to demo — let's talk.
