Practical notes on applying AI to engineering workflows — what helps, what hurts, and what to never let it touch.
Lessons from building ventures across continents — operations, decision-making, and the economics of doing the work.
Essays on infrastructure, design philosophy, and the craft of moving from drawings to durable construction.
Field notes and design thinking on soils, rock masses, and the underground openings cut through them.
Reading the ground — structure, lithology, and the stories rocks tell long before a project shows up.
Reading the Ground: What Rock Cores Actually Tell Us
A core box is more than a souvenir from a borehole. It is a one-to-one record of the ground a tunnel will pass through — if you know how to read it.

Empirical, analytical, numerical — none of them is right on its own. The craft is knowing which one to trust at which station.
AI for Geotechnical Reporting: A Pragmatic Playbook
Where AI actually saves time on a geotech report, where it quietly invents data, and how to deploy it without putting your stamp at risk.
From Akyempim to St. Louis: What Two Continents Taught Me About Ground
A pit in Ghana and a tunnel in Missouri are not as different as you would think. The ground talks the same — the budgets and standards just translate it differently.
