Kashif J.

Network security professional with a strong foundation in Linux administration, VMware, and Proxmox. I design, secure, and troubleshoot hybrid environments—from firewall policies and VPNs to virtual infrastructure health and disaster recovery. With a background in Linux administration and virtualization (VMware, Proxmox), I deliver comprehensive network and infrastructure solutions. Services I Offer 1) Network Security: Configure Cisco devices, firewall appliances (Cisco ASA/Firepower, pfSense), and secure VPNs (IPsec, OpenVPN, WireGuard). I implement robust security policies to protect your infrastructure . 2) Virtualization (VMware & Proxmox): Migrate, deploy, and manage production environments. I can assist with high availability, disaster recovery, Ceph storage, and performance optimization . 3) Linux Administration & Automation: Harden servers (SELinux, Firewalld), automate deployments with Ansible, and ensure system reliability. My focus is on automation and security . 4) Infrastructure Audits: Provide a comprehensive health, performance, and security audit of your physical and virtual network. I identify vulnerabilities and misconfigurations to fix them . What Sets Me Apart Bridge Between Virtualization and Security: Unlike a pure network engineer or pure sysadmin, I understand how traffic flows from the firewall through the hypervisor to the Linux OS . Certification Path: I am actively studying for CCNA and CCNP Security, bringing current, updated knowledge of network security standards . Automation-First Approach: I use Ansible to standardize configurations, eliminating human error and saving you time .
