Networking & Wi-Fi
Reliable, secure networks—designed, implemented, and supported. From edge switches and PoE to controller-based Wi-Fi, SD-WAN, and Zero Trust remote access, I build networks that are fast, resilient, and easy to operate.
LAN & Switching
- Core/edge design, stacking, L2/L3 segmentation
- VLANs, trunking, port profiles & access policies
- PoE/PoE+ budgets for APs, phones, CCTV & access control
- Spanning Tree, storm control & loop prevention
- Redundancy (MLAG/VPC) & hitless maintenance where possible
- QoS for voice/video; multicast & IGMP snooping
Routing, WAN & Internet
- Edge routing, NAT, policy-based routing & failover
- Dual-ISP design, LTE/5G backup, SD-WAN optimisation
- Site-to-site & hub-and-spoke VPN (IPsec/SSL)
- DNS/DHCP planning, IPAM & addressing standards
- Cloud on-ramps (Azure/M365) & private access
Wi-Fi Planning & Design
- Predictive & on-site surveys (heatmaps, SNR, CCI/ACI)
- AP placement, channel/power plans (2.4/5/6 GHz)
- Controller-based, cloud-managed & mesh topologies
- Capacity planning for dense & voice-over-Wi-Fi
- Outdoor & warehouse coverage (directional/omni)
Wi-Fi Security & Guest
- WPA3/Enterprise with 802.1X & RADIUS
- Identity-based access, PSK rotation, PPSK
- Guest portals, time-limited access, bandwidth caps
- Segmentation for IoT/CCTV/guests via VLANs & ACLs
- Wireless intrusion detection/prevention (WIDS/WIPS)
Network Security
- Next-gen firewalls, IDS/IPS, URL filtering & TLS inspection
- Micro-segmentation, ACLs, private VLANs
- NAC/802.1X for users & devices; posture checks
- Remote access: ZTNA/SASE, MFA & Conditional Access
- Logging to SIEM (Sentinel), alerting & compliance reports
Integration & Use-Cases
- CCTV & NVR networks (multicast, storage paths, QoS)
- Access control panels & relay I/O segments
- Microsoft 365/Teams QoS & ExpressRoute equivalents
- Azure hybrid connectivity (VPN/ER), private endpoints
- Home/Building automation VLANs & secure bridges
Monitoring & Troubleshooting
- SNMP/NetFlow/Telemetry—dashboards & alerting
- Syslog, packet capture & client health baselines
- Wi-Fi QoE checks, roaming analysis & sticky-client fixes
- ISP monitoring, SLA tracking & incident runbooks
Standards, Docs & Upgrades
- Config standards, templates & golden images
- Firmware cadence, staged rollouts & rollback plans
- Change control, versioned backups & RTO/RPO
- As-built diagrams, IP plans & handover guides
Need Faster, More Reliable Networking?
From new office builds to Wi-Fi fixes and multi-site SD-WAN, I’ll design a secure, resilient network with clean configs, clear docs, and measurable results.
