research, experiments and growth across software, supply chain and operations

About

Built by G. Geralcus. I come from logistics and supply chain, and now I also build the software, data systems, and automation that support the work.

This site is where I document what I'm building and learning. Not just supply chain. Anything worth understanding or improving ends up here.
