About

Hey, I’m Brian — an AI infrastructure and Software engineer based in Nairobi, Kenya. I build at the intersection of agent safety, autonomous systems, and full-stack engineering.

This is my corner of the internet. I’ll use it to share what I’m working on, what I’m learning, and occasionally what broke and why. I’ll also publish projects (deployed websites) and blog posts here — stick around.

Where it started

I started coding in 2021 while I was in university, where I graduated with Second Upper Honors in a BSc in Software Development.

I didn’t grow up loving code. The first line of code I ever wrote was in 2020 when I was selected for the course — but somewhere along the way I found a connection in it and I haven’t stopped since.

From 2023 to 2024, I worked on Remotasks helping train AI systems by teaching them what good looks like: selecting the best answer from a list, guiding step-by-step reasoning, and evaluating code quality against user-defined goals. That experience taught me how much craft goes into shaping model behavior — and how high the standards need to be.

Around the same period, I ran my own Shopify store as a real business. I sold to customers in the US and Canada, broke even, and made a healthy profit — while learning the full loop: product, marketing, fulfillment, and customer trust.

Building across industries

I’ve built across different domains — the common thread is always shipping reliable systems and learning fast.

I worked with Mlugha (a language-tech startup) on systems that supported language learning for kids in remote areas. I also worked remotely for Astora, a Nigeria-based company, building production-grade software in a distributed environment.

What I believe in is putting in the work and giving your best with what you have — despite limitations. I also believe in standing out in whatever you build, while still solving the problem at hand.

The AI turn

Over time my focus shifted from just building applications to building the infrastructure around AI: how to run autonomous systems safely, with the right isolation, policy enforcement, observability, and guardrails.

I’ve worked on multilingual NLP for Kenyan languages (Kikuyu, Kamba, Luo, Swahili, Somali) at Mlugha, and I’ve contributed to model training pipelines as an annotator and reviewer. I’m also curious about 3D: I’ve explored NeRFs and Gaussian splatting workflows through Nerfstudio for spatial assets.

Some nights — especially when I feel stressed or uncertain — I write Much more code because it calms me down. Like right now at 2:00AM.

What I’m working on now

Right now my focus is split between building my startup and going deeper on agent infrastructure.

I’m the founder of Melduo, an AI-powered platform for knowledge workers.

On the infrastructure side, I’m focused on what it actually takes to run agents safely in real production systems — execution isolation, policy enforcement, simulation-before-execution, observability, and a credential gateway.

Hackathons & shipping

I’ve won multiple hackathons and global competitions, including Tadhack twice in a row (2024 and 2025) and EarthAI 2025. I’ve also won regional and country-level hackathons across fintech, healthtech, and agritech.

Those competitions taught me how to go from zero to something working in 48 hours — a skill that transfers to everything.

Books that shaped me

I read a lot. A few books that have stuck with me:

• How to Get Rich by Felix Dennis — a reminder that even when going through hell, you keep going, and you keep trying.

• The Alchemist — the courage to go for the unknown without letting fear hold you back.

• Zero to One by Peter Thiel — a book I revisit often on what innovation means, and why happy companies are always different.

• Business @ the Speed of Thought (Bill Gates) and related writing — especially the idea of a digital nervous system for a business.

Why this site

I want to document the journey — technical deep dives, founder lessons, and the things I learned the hard way building from Nairobi and other countries i visit.

African developers are building serious things. I want this site to be a small piece of evidence of that.
