open to apprenticeship — systems & network administration

Muhammed Lami Jammeh
Systems & Network Administrator in training.

TSSR-qualified this year. I build, break, and secure networks — from VLAN segmentation to firewall rules — and I'm looking for an apprenticeship where I can keep doing that on real infrastructure.

Grounded in fundamentals, built for real networks.

I'm a cybersecurity and systems administration student based in France, currently holding the TSSR qualification (Technicien Supérieur Systèmes et Réseaux). My focus is on the practical side of the field: configuring and hardening infrastructure, managing Linux and Windows environments, and understanding networks well enough to secure them.

Outside coursework, I run my own home lab to test firewall rules, VLAN segmentation, and monitoring setups — because reading about a concept and actually deploying it are very different skills. I'm now looking for an apprenticeship (alternance) where I can apply this hands-on, under people who'll push me further.

Labs and builds from my home network.

Flagship Lab

Enterprise Network Simulation

Built a small virtual enterprise from scratch: pfSense for routing/firewall, a Windows Server domain controller (AD DS, DNS, DHCP), a domain-joined Windows client, Ubuntu Server, and Kali Linux for security testing — with SMB/LDAP enumeration and BloodHound prepared for AD attack-path analysis.

Linux / Windows Integration

Ubuntu–Active Directory Integration

Joined an Ubuntu Server to a Windows Active Directory domain using realmd and Kerberos — configuring static networking with Netplan, verifying domain discovery, and authenticating via kinit/klist across a segmented pfSense network.

Windows Domain Administration Lab

Deployed a Windows Server 2022 domain controller with AD DS, created domain users and security groups, configured Group Policy, and monitored authentication logs from a domain-joined Windows 10 client.
