Hersi.


Notes from inside the workon infrastructure, Go, and the operational reality of running systems from the cloud to the edge. I build developer tools like NextDeploy, payment platforms like PesaStream, and share honest essays on what actually holds up in production.

I built a deployment engine 👀

NextDeploy: Run Next.js on AWS without DevOps headaches.

Tired of massive CloudFormation manifests, bloated cloud bills, and clunky infrastructure setups? I authored NextDeploy—a single standalone Go CLI that bundles, provisions, and serves Next.js directly on your own AWS infrastructure in under 60 seconds.

Backstory

Hey, I’m Hersi 👋

Software Engineer · Nairobi, Kenya

I’m a software engineer and founder based in Nairobi. Over the past several years, I’ve been building production backends, payment rails, and cloud tools—all while writing down the practical mechanics of how systems behave under real traffic.

My focus centers on high-leverage software: building NextDeploy so developers don't have to fear cloud deployments, founding PesaStream to modernize retail POS systems in Africa, and contributing back to the open-source Go ecosystem.

"No fluff, no theoretical posturing—just clean code, verifiable tests, and systems that hold up when reality pushes back."
