About

Platform engineering at scale

I lead platform ecosystems — cloud governance, developer experience, and production learning infrastructure.

How my roles fit together

Campusna and AfricaTek operate within the same education ecosystem. I am Technical Manager at Campusna — I lead platform architecture, cloud organization, and client delivery. That work is employer IP; this site describes my technical leadership, not products I personally own.

DarDev Solutions is the company I co-founded and serve as CTO. Products like 20 and Hesabi, the Workspace platform, and client engagements like CleanCH are mine to speak about as founder and technical lead. AI orchestration research lives in DarDev Studio (case study and systems architecture on this site).

The arc is intentional: Holberton student → platform builder → Technical Manager → CTO — hands-on architecture with engineering leadership at institutional scale.

AI orchestration systems

Engineering program and product work on DarDev Studio. Long-form article: /writing/ai-orchestration-systems-research. Case study: /case-studies/dardev-studio-ai-orchestration.

Internal developer platforms

VS Code online, JupyterHub, lab provisioning, and employee intranet on Kubernetes — with unified identity through Keycloak, LDAP, and OAuth2/OIDC. Led as Technical Manager at Campusna.

Multi-tenant SaaS

Moodle product layer with custom extensions, payment microservices on ECS, teacher analytics with per-student cloud cost tracking, and auto-grading at curriculum scale.

Cloud governance

Multi-account AWS Organization — landing zone design, OU structure, SCP strategy, SSO, student lab account vending, and IaC across Terraform, CloudFormation, and CDK. 100+ accounts managed over the platform lifecycle.

Educational infrastructure

Learning platforms supporting 40,000+ learners across 7+ institutional deployments — national telecom LMS, university pathways, ELIFE regional programs, EU-funded TechLink, and Holberton international pathways.

DarDev products & delivery

As CTO and co-founder: 20 school management SaaS, Hesabi Tunisia ERP, Netverse, CleanCH EU client delivery, and the DarDev Workspace company platform — launched 2026 products while maintaining engineering standards.

I work on Platform Engineering Lead, Infrastructure Engineering Manager, and Technical Director tracks. See contact for roles I am open to, or explore live deployments for public proof.
