I'm a developer in Berlin. I work across data systems, automation, and applied AI.
I came to software through psychology, neuroscience, and medical research rather than a traditional computer-science path. That background still shapes how I think: systems are built for people, measurements have context, and elegant machinery is useless when it answers the wrong question.
Cortez Builds identity record lists my current contact key and the status of future credentials. This GitHub page is a provisional discovery location for a signed record that can later be served from more than one place.
My professional work has included data platforms, a customer-facing RAG assistant for industrial energy users, engineering leadership, and running a small automation business. Python, SQL, and Linux are familiar territory. I enjoy following a problem across the boundaries between the software, the people using it, and the decisions it is supposed to help them make.
I'm interested in privacy-preserving and local-first systems, evidence-heavy research, electronic music, and DJ tooling. The music projects are one place those interests meet: discovery, data, ownership, and the pleasure of finding something worth playing.
