What I'm looking for

I’m open to remote work in the EU, hybrid work in Tunis, or relocation.

At Campusna, I led the architecture and delivery of MTN Cameroon E-Campus on AWS ECS Fargate. The live platform improved payment transaction success rate and API response time by about 40%.

I designed and operate a 29-account AWS Organization with a landing zone, SSO, SCPs, and infrastructure as code. Platform rationalization, FinOps, and rightsizing reduced cloud costs by about 47%.

Across Campusna, AfricaTek Academy, and Holberton School Tunisia, I progressed from teaching assistance to curriculum and full-stack delivery, then Technical Manager and Platform Lead. I led teams of up to 35 people and supported production platforms serving more than 40,000 learners.

I co-founded DarDev Solutions as CTO, where we launched Hesabi and a 20-school EMIS platform in 2026. I’m open to remote roles in the EU, hybrid work in Tunis, or relocation.
