Bernard Katamanso

Engineer & Pan-Africanist 🇬🇭

I build infrastructure and tools that shape how people create software. I work from Ghana, and I believe in engineering that is deliberate, precise, and built to last.

I write about what I build and what I learn along the way: systems architecture, developer tooling, infrastructure, and the engineering problems that keep me up at night. I build from Ghana because I believe world-class engineering is about depth and craft, not geography.

There Is No Order of Operations

Here is something I think is really interesting about mathematics that we usually never stop to notice: there isn’t actually some inherent “order of operations” built into the universe.
