Alex Marinelli
Data Builder | Performance & Automation Systems
I build systems that remove friction from real operations.
Most of my work starts in ambiguity with scattered data, inconsistent processes, and unclear ownership. I turn that into automated pipelines, clear metrics, and tools that help people make faster decisions.
I've built workflow systems and analytics tools across finance, retail, and sport. The common thread is solving high-context problems with simple, robust systems that scale.
Discuss Systems & Ideas
I enjoy talking through real-world data and workflow problems across sport, commerce, and operations. If you're exploring analytics, automation, or decision tooling, I'm always open to a conversation.
