Tech lead & consultant · Architecture, digital products and AI

An infotronics engineer from Saint Jérôme Polytechnic, I cut my teeth on award-winning mobile apps while still at school, then led SOGEFI's development team, built the open-source GeOsm mapping platform on OpenStreetMap and developed for clients as far as Germany. At Orange Cameroon since 2023 (first as an IS engineer on the Orange Money project, now Senior Lead in the Platforms & Services department of the IT division), I work where reliability, scalability and performance are non-negotiable. Alongside, I advise organisations (architecture, project scoping, adopting AI and agents) and build complete products (fintech, messaging, delivery, AI SaaS). I work every day with AI agents such as Claude, Gemini and Gemma (including locally) to ship faster without sacrificing maintainability. I have led more than 6 teams and trained or mentored more than 20 people: co-organiser of Flutter Cameroon and trainer at GDG Douala, I pass on what I learn.

The engineering student already shipping

As an infotronics engineering student at Saint Jérôme, I built my first apps for real users: the MySJD student app, the QR-code ticketing for Ubuntu 2018, and a PPE-tracking app for Eneo that won the most innovative project award.

First DevFest, first GPChat

As an intern at SOGEFI I built the first version of Position. The same year I stepped on the DevFest Douala stage for the first time to talk about Flutter, and published GPChat on the Play Store and the App Store.

Lead developer and open-source builder

Heading SOGEFI's development team, I led 5 developers and built GeOsm, an open-source mapping platform on OpenStreetMap. Alongside: a remote mission for Coockeroo in Germany, co-organising Flutter Cameroon, and my plugins published on pub.dev.

Orange Money: the discipline of critical systems

An IS engineer at Orange Cameroon, on a service millions of people use every day: analysing needs, designing, supervising deployments, meeting SLAs. It's where I learned the discipline of critical systems and led a USSD journey automation project handling 10,000+ concurrent requests. Since June 2026 I've been a Senior Lead in the Platforms & Services department of its IT division (DSI).

How I work

01

End to end

API, web, mobile, servers: I ship the whole product, not a slice.

02

Robust by default

Tests, security, backups and observability are part of the product from day one.

03

Built for the field

Slow networks, Mobile Money, multilingual users: I design for real African usage.

Away from the code

A gamer, always.
