Need a senior network engineer for your after-hours change window? I'm in Melbourne, Australia, so your nights and weekends in the US and Europe are my normal working day. I'm an ex-Cisco technical lead, with 15+ years on Cisco, Juniper, Fortinet and Check Point networks. WHY HIRE ME OVER OTHER NETWORK FREELANCERS • I've worked on the vendor side. I spent years at Cisco TAC, Juniper escalation and as a Cisco Network and Security Lead Engineer. I know how these products behave when they fail and how the vendor's own engineers troubleshoot them. Most freelancers learned from the outside. • I'm awake during your maintenance window. You get a fresh senior engineer at 2am your time, with no overtime premium. • I do security as well as networking. I'm CISM certified as well as CCNP and JNCIS, so firewall rules, VPNs and segmentation get designed with risk and audit in mind, not only "make it ping". • I work across many vendors. Cisco, Juniper, Palo Alto, Fortinet, Check Point, F5, Meraki, Azure and AWS. I'm comfortable in mixed environments and in migrations from one vendor to another. • You get clear documentation. Each job ends with a short write-up: what was wrong, what I changed, the rollback steps, and what to watch next. WHAT I'M HIRED FOR MOST • Firewall builds, migrations and troubleshooting: Cisco ASA/Firepower (FTD/FMC), Palo Alto, FortiGate, Check Point • Site-to-site and remote-access VPNs, including Azure and AWS IPsec connectivity • Azure networking: VNets, VPN Gateway, NSGs, Azure Firewall and hybrid on-prem to Azure connectivity • Zero Trust remote access: Cloudflare Zero Trust (ZTNA, WARP, Cloudflare Tunnel) • Routing and switching: BGP, OSPF, EIGRP, MPLS, VLANs, Nexus, Catalyst, ISR/ASR • Cisco ACI/APIC, DNA Center, ISE (802.1X, posture, guest) • SD-WAN: Cisco Viptela, Meraki, VeloCloud, Versa • Cisco Meraki: MX security and SD-WAN, MS switching, MR wireless; plus Cisco WLC • Load balancers: F5 • Network automation with Python and Ansible, plus AI-assisted ticket triage and runbooks • Network audits, design reviews and upgrade planning HOW I WORK 1. A quick call or message to understand the problem and the risk. 2. A clear plan, including rollback, before anything changes in production. 3. The change is done in your agreed window, and I stay on until it's verified. 4. A handover note so your team owns the result. Every client who has left feedback on my Upwork jobs has rated me 5.0. They mostly describe me as responsive, quick to the point and committed to quality. Send me your topology, the error or the project goal. I'll tell you honestly whether I'm the right fit and how I'd approach it.
