Dakar, Senegal. Open to new projects.

André Sarr

Some for ministries. One for the shop on your street.

I’m a computer science engineer. I have spent more than two years building platforms for ministries and public institutions. Today I also lead Ubbi, a project that helps small shops sell online.

a whole country can rely on is the real work.

01

Safe from day one

Public systems get audited. I think about attacks before I write the first line, not the week before launch.

02

Fast, even on a weak signal

Most people here browse on a phone, often on 3G. If the page is slow for them, it doesn’t work. I build for them first.

03

Easy to take over

Someone else will look after the code once I’m gone. I write it clearly and explain it, so they never have to start over.

Ubbi

Here, most shop owners sell on WhatsApp, one message at a time. I wanted them to have a real online shop. Keep scrolling, it’s opening.

raio

Payment infrastructure · Rust

A free, open base for instant payments, so different providers, currencies and countries can work together.

It takes what works in Brazil’s Pix (pay with a simple alias, money that arrives at any hour, a QR code you can copy) and makes it reusable by anyone. It handles currencies without cents, like the CFA franc, and follows the standards used in this region: EMVCo QR, ISO 20022, GSMA Mobile Money and PAPSS.

MediRecord

Health information system

Doctors manage medical records on a dashboard. Patients ask questions about their own record on WhatsApp.

Medical documents are read and filed automatically. When a patient asks something, the answer comes from their own file, not from general advice found online. Built for a country where everyone already uses WhatsApp.
