Israel Estévez Hatchuell | Data Engineer & Architect

Building robust & scalable data systems.

Forever in learning mode.

I bridge the gap between complex engineering and business value. With a hybrid background in Computer Science and Business Administration, I design scalable data pipelines, asynchronous architectures, and BI solutions that drive strategic decisions.
