About Jacob

IT & Systems Administration Support Consultant

I support companies and their employees to ensure the stability, security, and performance of their IT environment. My goal is to minimize your downtime and make technology simple for your users.

🔧 What I can do for you:

Technical Support (L1/L2/L3): Quick diagnosis and resolution of hardware and software incidents (Helpdesk and on-site).

Systems Administration: Management of IT assets, Windows Server environments, and Active Directory.

Cloud & Tools Management: Administration of Microsoft 365 / Office 365 accounts and access management.

Operational Maintenance (MCO): Preventive maintenance, updates, and security of workstations.

🌟 My added value:

Beyond technical expertise, I place a high value on customer service quality. I am educational, patient, and ensure clear follow-up for each user. Trilingual (French, English, Hebrew), I adapt easily to international environments.

Feel free to contact me to discuss your system support or administration needs.
