}// about
Data engineering meets product.
I build reliable batch and streaming pipelines, model data for analytics, and automate infrastructure as code. I care about systems that are correct, observable, and maintainable — not just demos that work once.
Through Aragón Tecnologia I take products from idea to production: architecture, development, deployment, and operations — including zero-downtime deploys and AI integrated where it genuinely improves the product.
