About me

Let me introduce myself

To build technologies that make quality healthcare more accessible, intelligent, and equitable across Africa.

The future of healthcare sits where medicine, technology, and human-centred design meet. I am less interested in tools that work in a well-funded demo than in ones that survive a real ward on a bad day.

That means building for the constraints people actually have. Low data. Unreliable power. A phone rather than a computer. A language a government form does not offer. Solutions that empower health workers and hold up in underserved communities, or they do not count.

How it goes

Process

  1. 01

    Let's talk

    We start with the actual problem and the constraints around it. Who uses this, on what phone, with what connection.

  2. 02

    Build and test

    I build the smallest thing that proves the idea, then put it in front of real users and fix what breaks.

  3. 03

    Ship and support

    You get the code, the documentation, and someone who stays reachable after launch.

What 240 people taught me about health chatbots

Four months of running two WhatsApp health bots in Cameroon, and the one user behaviour that changed how I think about building them.

Before you ask

FAQ

Frequently asked

What kind of work do you take on?
Health technology mostly. Blood and donor logistics, WhatsApp health services, clinical data and risk models, and research support. If it touches care delivery in a low-resource setting, it is probably a fit. If it does not, I will say so rather than take the work.
Are you a nurse or a developer?
Both, and that is the point. I trained and worked as a registered nurse before I learned to code, so I build from inside the workflow instead of guessing at it. It means I ask about the ward round and the network before I ask about the tech stack.
How long does a project take?
It depends on what it is. A WhatsApp bot with a handful of flows is a matter of weeks. A platform with dashboards, roles, and real users behind it runs into months. I would rather give you a real timeline after one conversation than a comfortable one before it.
What does it cost?
I price per project, not per hour, and the number comes from scope: how many flows, how many user types, whether there is existing data to work with, and how much support you want after launch. Rates are set for the Cameroonian market and I am straight about what fits a given budget. Book a call and we settle on a figure together.
Do you work with people outside Cameroon?
Yes. Most of the work is grounded here, and that constraint is usually the useful part. I work in English and French.
What do you need from me to start?
The problem, who it affects, and what they are using now. Screenshots of the current process help more than a specification does. If there is data already, tell me what shape it is in honestly, including if it is messy.
