What I do: ✔ IT Support & Helpdesk — remote troubleshooting, ticket handling (Tier 1–3), user onboarding/offboarding, printer and endpoint issues, and ongoing support contracts for businesses and MSPs ✔ 3CX VoIP — new deployments, V18→V20 migrations, SIP trunk configuration (Twilio, Broadvoice), IVR, queues, DID routing, integrations, and troubleshooting ✔ FortiGate firewalls — SSL-VPN setup for remote teams, firewall policies, split tunneling, secure remote access, and web filtering ✔ VMware virtualization — ESXi and vCenter administration, VM provisioning, migrations (P2V/V2V), performance troubleshooting, and host maintenance ✔ Backup & disaster recovery — Veeam configuration, backup health checks, and restore testing for VMware environments ✔ Infrastructure & Information Security — network segmentation (VLANs), firewall hardening, VPN security, access control, MFA rollout, patch management, and security best practices to protect your business data ✔ Microsoft 365 & Intune — tenant administration, Exchange Online, device enrollment, and MDM policies ✔ Networking — network design & deployments, troubleshooting, and network optimization ✔ Server administration — Windows Server, RHEL/Linux, Active Directory, and day-to-day IT support How I work: I follow ITIL-aligned practices — structured incident and change management, proper documentation, and root-cause fixes instead of quick patches.

I've handled everything from single urgent fixes to long-term support contracts, and my clients keep coming back because things get done right the first time.
