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.

Core Capabilities
• Performance Analytics
• Data Systems
• Automation
• Full-Stack Prototyping
• Operational Intelligence

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.
