What I focus on

I write for CTOs and technical leaders who want clarity, not hype.

Agents

How agent systems actually behave in production — tool use, reliability, and failure modes.

Big Data + LLMs

Where LLMs help, where they hallucinate, and how to connect them to real datasets safely.

Retail Analytics

Pragmatic metrics, attribution tradeoffs, and the gap between dashboards and decisions.

PPC Analytics

What good looks like when spend is real, data is messy, and stakeholders want answers fast.
