How I used existing Home Assistant telemetry to estimate a 26,600-gallon pool and calculate filtration turnover without adding permanent sensors.

I build things
to understand them.
I have spent thirty years taking systems apart, making them work, and explaining what I found. These days that means cloud data, AI infrastructure, and a greenhouse in my backyard.

Infrastructure beneath frontier AI
From 2017 through 2025, I led Azure Blob product work, including the Azure-side storage relationship supporting OpenAI and Microsoft AI. OpenAI’s 2019 Dota 2 report names me under Microsoft Azure Support. At SNIA SDC 2024, Jegan Devaraju and I explained how Azure Blob supported large-scale model training.
My part was product and infrastructure work, alongside a much larger team.

Notes from problems I wanted to solve.
The collection currently includes 40 articles: 33 technical pieces and 7 essays. Some solved an immediate problem; others captured what I believed at the time. I have left both kinds here.
