Rasolomanana Albert

Systems and network administrator with several years of experience in managing complete IT infrastructures, from security to user support. I manage a daily environment of 76 users including Windows Server, pfSense firewalls, business email, and virtualization.

My expertise covers the entire chain: migration and administration of mail servers (with SPF/DKIM/DMARC configuration), hardening network security, intrusion detection and firewall management, as well as developing custom internal tools (Python) to automate monitoring and anomaly detection on the network.

What sets me apart: I don't just apply off-the-shelf solutions — I develop my own tools when market solutions don't meet the need, and I rigorously document every intervention to ensure complete transparency.

Rigorous, autonomous, and responsive, I work on both specific missions (security audit, server migration, infrastructure hardening) and recurring remote support. Available to discuss your needs, regardless of the time zone.
