What I'm looking for

I’m looking for an entry role where I can deliver secure networks (VPN/SSH/DNS), deploy cloud infrastructure on Azure, and build practical AI features with RAG—learning fast while contributing hands-on to reliability and security.

I’m a student in “Ingénierie Réseaux & Télécommunications” at INSAT (Tunis), focused on building reliable network services and secure infrastructure. Through “Stagiaire en Réseaux et Sécurité,” I implemented a “solution VPN sécurisée” in a cloud environment using AlmaLinux and Pritunl/OpenVPN, and I hardened access with SSH key-based authentication.

I also enjoy end-to-end engineering: I deployed and configured VMs on VMware ESXi (IP addressing, SSH, DNS, gateways, NSG) and strengthened sshd_config by disabling password auth and limiting connection attempts. On top of that, I build AI-enabled products—like my “Second Brain – Assistant IA Personnel,” using LangChain with RAG (ChromaDB) and a Neo4j knowledge graph—while developing cloud architectures and experimenting with Deep Learning and image processing using TensorFlow/Keras and OpenCV.
