I take ownership of production platforms — the product, the infrastructure and the bill that follows — across LatAm and the US. Below is what exists because of that, with the evidence beside it — or, where a client's data isn't mine to publish, a note saying so.

How I work

I listen first

Before I touch anything I want to understand the business the system serves — what hurts, what it costs you, and what “done” looks like to the people paying for it.

I own it end to end

Requirement to production, and afterwards. Not a ticket handed back — the code, the infrastructure and the pipeline stay mine once they ship.

I leave a trail

Every change carries its reason and its number, so the next engineer — or you, in six months — can see why it was worth doing.

If there is a platform that needs an owner — the product, the infrastructure and the bill — I would like to hear about it.
