What I'm looking for

I am seeking a hands-on network/systems role where I can design and secure enterprise networks, lead infrastructure projects, and grow in cloud and virtualization within a collaborative, security-focused organization.

I am a BS Software Engineering graduate with 7+ years' hands-on experience as a certified CCNP, HCIP and MCSE network and systems engineer, delivering enterprise-grade support across UAE and Pakistan.

I design, implement and maintain firewalls (FortiGate, SonicWALL), core routing and switching (Cisco, Huawei), wireless solutions (TP‑LINK Omada, Huawei WLC), virtualization (vSphere/vCenter HCI) and backup/replication (VEEAM), and I manage Office 365 and Google Suite security and migrations.

I lead procurement and project rollouts, troubleshoot complex faults to root cause, administer AD/DNS and disaster recovery systems, and coordinate vendors and subcontractors to ensure reliable, secure infrastructure operations.
