About / Full-Stack & Cybersecurity Analyst

I build software that people actually rely on. Then, I do my absolute best to break it into pieces before anyone else can.

I work with business owners who need something that sells, and with teams who need someone to own a feature end to end.

01 / Background

Computer Science at Maasai Mara University, then straight into shipping. I take work from an empty schema to a deployed UI without handing it off halfway.

I put language models into products where they earn their place. What I send them matters more than which one I picked, so I spend the time on the filtering and the prompts rather than shopping for a bigger model.

The security habit came from TryHackMe, CyberDefenders blue team exercises, an ISC2 candidacy and the Moringa bootcamp, where the work was log analysis, malware detection and picking indicators of compromise out of noise. It means I build assuming someone will try the front door.

I led a student tech work group and ran sessions with GDSC, which is where I learned to explain a system to people who did not build it.

Pxum Studio

Client work goes out under Pxum Studio

Pxum Studio is the name I build under when the work is for a business. I founded it and I run it. Every client project in this portfolio was delivered through it.

The independent projects are mine alone. That is the difference between something I built to understand it and something a business now runs on.
