About

I’m Alex Celis-Copelotti, a Python engineer focused on designing automation, data, and web solutions.

I work with stakeholders to translate ideas into structured workflows and real tools. This means building automations that remove repetitive work, analyzing data to reveal what’s happening under the hood while communicating the results clearly, and designing web interfaces that are easy to understand and access.
