Hello, I'm Bernard Katamanso

Welcome. If we haven’t met, here’s the short version: I’m a software engineer and Tech Lead from Ghana who believes technology can — and should — be a force for equity across Africa and the global South.

I write about software engineering, systems architecture, programming language theory, and the craft of building things that matter. This post is a quick tour of who I am, what I do, and where to find me.

Who I Am

I’m Bernard Kirk Adjarnor Katamanso, though I usually go by Bernard Katamanso. I’m the Tech Lead at Orcta Technologies, where I build scalable systems and lead engineering efforts. I also work on developer tooling, SDKs, and infrastructure — the kind of work that makes other people’s work easier.

Beyond the code, I’m a Pan-Africanist. I believe that the next wave of global innovation will come from Africa, and I want to be part of building the foundations for it — through open-source tools, technical writing, mentorship, and direct engineering work.

Where to Find Me

I maintain a few corners of the web:

• adjarnor.dev — This site. Technical blog, projects, and writing.
• folio.adjarnor.dev — My portfolio and professional background.
• studio.adjarnor.dev — Photography. I also shoot.
• Substack — Longer-form essays on engineering, deep work, and Pan-Africanism.
• GitHub — Open-source work: SDKs, CLIs, tools, and experiments.
• X / Twitter — Short-form thoughts and links.

Search my name online and you’ll find talks, projects, and writing across these platforms.

What This Blog Is About

This is where I publish technical deep-dives — the kind of posts that take time to research and write. Expect content on:

• Systems architecture and distributed systems
• Programming languages and type theory (generics, type systems, compilers)
• Go, TypeScript, and systems programming
• Engineering craft — testing, error handling, code design
• AI and industrial systems — anomaly detection, predictive maintenance, ML in production
• Pan-African tech — building for and from the continent

Posts will include interactive code playgrounds, math rendering with KaTeX, diagrams, and callout boxes. Here’s a quick demo of each:

Let’s Build

I believe the best way to learn is to build and share. This blog is my contribution to that cycle — I learn by writing, and I hope you learn by reading.

If something here helps you, share it with someone who might benefit. If you disagree with something, tell me on X. And if you’re building something interesting in African tech, I’d love to hear about it.

Thanks for stopping by. Let’s build.
