Infrastructure & Networking¶
Cisco¶
Full product line experience across the Cisco portfolio:
Switching¶
- Catalyst 6500 platform — deep chassis-level experience including Cat OS, Hybrid mode, native IOS, Supervisor 720, Supervisor 2T, MSFC, and associated service modules
- Access, aggregation, and core layer switching
- Top of rack deployments
- Industrial and embedded variants for OT environments (IE series)
- Per-VLAN Spanning Tree (PVST+), Rapid PVST+
- SVIs, inter-VLAN routing, DHCP relay
Routing¶
- BGP (eBGP/iBGP), OSPF, EIGRP
- Static and policy-based routing
- Router platforms across the ISR and ASR families
Security¶
- ASA firewall platforms — deployment, rule management, VPN termination
- Site-to-site and remote access VPN
- ACLs, zone-based firewalling
Meraki Enterprise¶
Currently managing a full enterprise Meraki stack end to end:
- Core switching through top of rack
- Dashboard-managed deployment at scale
- Template-based configuration management
- Integrated wireless (MR series)
- SD-WAN capabilities
Starlink¶
Engineered the deployment of over 100 Starlink-enabled systems across a major energy operation:
- Plant facilities — permanent installations with wired backhaul failover
- Operator trucks — mobile deployments, ruggedized mounting, power management
- Integration — Starlink as primary or failover WAN, managed alongside existing RF and wired backhaul
- Operational challenges — thermal management, obstructed sky views at remote locations, firmware management across fleet
Sophos¶
- Sophos firewall and endpoint integration
- Unified threat management alongside Cisco/Meraki infrastructure
Design Principles¶
The networking layer exists to serve the control systems. Design decisions are driven by:
- Reliability — a wellpad going offline means production stops. Redundancy isn't optional.
- Simplicity — every protocol and feature must justify its presence. Complexity is a liability in the field.
- Serviceability — when something breaks at a remote site, the fix needs to be achievable by the person who happens to be there, not a specialist.
- Security — IT/OT segmentation, least privilege, defense in depth. The converged network can't become a lateral movement path.
