I design fit-for-purpose infrastructure that holds up under pressure without torching the budget. I build and run multivendor production environments where systems must behave predictably through load, change, and failure. I own systems end-to-end: architecture, deployment, operations, and incident response. I kill manual toil with IaC and repeatable workflows, eradicate configuration drift, convert tribal knowledge into clean diagrams, runbooks, and a single source of truth. Security is built into the design through segmentation, least-privilege access, and automated controls, with systems documented and monitored to support audits, security incidents, and ongoing operations. I’ve seen the carnage of failed changes, vague handovers, audit nightmares, and undocumented systems that bleed operational risk daily. That’s why I build lean, observable, boringly stable platforms that scale without drama and cost less to run long-term. Experienced across enterprise, data center, and cloud environments, with industry exposure spanning telecoms, vendor support, MSP operations, financial services, low-latency trading, and large-scale service providers. 💻TECH SKILLS🥷 🌐Networking: WAN, LAN, WLAN(Meraki, UniFi), VLANs, VXLANs, IPv6, NAT, RIP, OSPF, BGP, VRF, ACLs, QoS, VPNs, DHCP, DNS, NFV 📦Virtualization: VMware, OpenStack, Hyper-V, KVM, Proxmox, Docker, SR-IOV, SAN ☁️Cloud: AWS(EC2, VPC, Flow Logs, S3, IAM, CloudWatch, WorkSpaces, WAFR), Azure(VMs, AD, Networking), Google Workspace, Office 365 ⚙️OS: Cisco IOS, Cisco NX-OS, Dell OS10, Arista EOS, Windows Server(PowerShell, AD, Group Policy, Exchange), Linux(Bash, IPtables, Permissions, Nginx), macOS 🔐Security: Firewalls(Palo Alto, FortiGate, SonicWall), CASB(Netskope), SIEM(Rapid7), MDM(MaaS360), IAM(Okta, Centrify, CyberArk), Email(Mimecast) 🤖Automation: Python(Jinja2), APIs(RESTful, NETCONF, RESTCONF), XML, JSON, YAML, YANG, Terraform, Ansible, GitHub 🛠️Tools: Wireshark, Nmap, iPerf, Cisco CIMC, Dell iDRAC, Dell OpenManage, Veeam, OpenVAS, GitHub, Postman, ManageEngine, PRTG, Zabbix, Observium, Graylog, Passbolt, NetBox, Visio, Itemit

Networks look like a puzzle to most people. To me, they're just a problem I know how to solve. What I deliver: Network audits & optimization Design & migration - new builds, office expansion, hybrid/cloud Security hardening - ACLs, segmentation, firewall policies, VPNs Troubleshooting escalations - when your team is stuck, I step in. Root causes, not symptoms. Mentoring / on-call - fractional architect for teams without a full-time role Technical depth: Areas and stack: Routing & switching - Multi-vendor. Security - PFSense, OPNSense, Fortinet, Palo Alto, Cisco ASA/FTD, VPNs, segmentation Linux - Any distro, bash scripting, performance tuning Virtualization - Proxmox, VMware, Hyper-V, KVM Automation - Ansible, Terraform Observability - Zabbix, Splunk, SNMP, syslog Background: 30+ years in the field, 7 as a Cisco Networking Academy Manager and Instructor. I've designed large-scale enterprise networks for government, healthcare, and finance — example a maternity center where downtime isn't an option, campus networks for universities, and an airport-wide wireless solution. I've delivered security projects following both international best practices and local regulatory standards. I've trained and worked alongside engineers across Australia, New Zealand, the US, and beyond, and I learn as much from them as they do from me. I work self-paced, lead or go solo, and I'm still adding tools: Proxmox and Splunk a few years ago, Ansible and Terraform last year. This year I'm diving into AI infrastructure — GPU clusters, distributed training, high-throughput data pipelines. I'm also building deeper into Python and scripting to support automation and development from the ground up. How I work: Clear communication, no jargon. English fluent.
