About

Full-stack development, paired with growth marketing.

I run SuperAnnex Technologies, a Dar es Salaam studio I founded in 2022 that builds websites, applications, and brand systems for businesses across Tanzania — and then runs the Meta Ads campaigns that keep bringing customers back to them.

Day to day that means writing Laravel and Alpine.js for client platforms, designing systems in Tailwind CSS, and building the lead-automation pipelines (Make.com into Google Sheets) that turn ad spend into booked jobs.

I work across the full lifecycle — from the first line of code to the ad account that keeps the business growing after launch.
