About

From Tunis to Paris, through production

A product only exists once it runs in production.

Île-de-France · France

It all starts in Tunis. An engineering student at INSAT — DevOps & Cloud Computing degree earned in 2020 — I didn't wait for graduation to start working: interfaces and UX at Speegar, mobile applications at Peaksource Vision, then full-stack development and building a DevOps culture at Vynd. Today I live in Île-de-France and work across France and Europe.

The field then taught me everything: migrating Zaion from bare metal to AWS, with Kubernetes clusters running more than 1,000 pods; leading 17 engineers at BNP Paribas to move 140 machines to the cloud, in a regulated banking environment; operating a DevOps platform at ENGIE serving more than 600 organizations and 10,000 users; auditing the multi-cluster OpenShift infrastructure of the Government of Monaco, spanning AWS and a sovereign cloud.

I never chose between infrastructure and product. I wrote web applications, APIs, and an iOS app before diving into Kubernetes — and I still write code today: tooling in Go and Python, Next.js applications, all in service of the platforms I operate. This dual profile lets me deliver a complete product, from the idea all the way to running in production.

One conviction serves as my compass: a product only exists once it runs in production. It is what drove me to earn the 16 certifications of the Golden Kubestronaut track — to master every layer of the system, from networking to observability — and it is what frames every engagement: an architecture is only worth what it becomes once deployed, monitored, and operated.
