Background

Twenty years of building systems, leading teams, and shipping under real constraints — the record.

Portrait of Billa Coetsee

I’ve spent more than twenty years building technical systems and leading the people who build them — as an architect and engineer, and as the person accountable for the strategy around the work. The shape of the career is deliberate: enterprise infrastructure and security early on, a term of industry-body leadership in the middle, and most recently protocol engineering for self-sovereign blockchain networks. Three of those networks are now launched and running, across the Cosmos and Sui ecosystems.

What ties it together is a way of working more than any single domain. I’m most useful at the boundary between people and machines — turning business intent into technical specification, and technical reality back into terms a board can act on — and I build teams that cooperate rather than compete. What follows is the record. The thinking behind it lives on the rest of this site.
