Hi, I'm Adam 👋

Senior Customer Engineer @Microsoft · Azure Networking Specialist

I'm a Senior Customer Engineer at Microsoft focused mostly on Azure networking — helping enterprises design hub-and-spoke, Virtual WAN, ExpressRoute, hybrid connectivity, and SD-WAN integrations. This profile is a curated index of the hands-on labs, architecture articles, and troubleshooting toolkits I've built while working with customers. Most content is reproducible end-to-end so you can deploy, break, and learn from real Azure topologies.

🔭 Currently exploring: AVNM Part Two · ExpressRoute monitoring · vWAN routing intent with forced tunneling 💬 Ask me about: vWAN custom routing · ExR Fastpath · ARS dual-home · BGP-over-IPsec · NAT Gateway

🧪 Labs

BGP over IPSec · Blue -Yellow Isolation — Custom vHub routing with Cisco CSR branch over IPsec + BGP, with rt_yellow / rt_blue route table isolation
Azure Virtual Network Manager — Walk-throughs for Mesh, Hub-and-Spoke, and Hub-and-Spoke + Global Mesh
AVNM Part Two — Advanced AVNM scenarios (work in progress)
Route Server Dual Home — Highly available ARS across two hubs with BGP + VNet-to-VNet IPsec
Dual vWAN Secure Hubs + BGP-over-IPsec — Dual-region secured vWAN hubs with Private Routing Intent and full bow-tie BGP-over-IPsec branches using Strongwan (Bicep / Terraform / CLI / PowerShell)
ILB With Apache Server via Vnet Peering -Client connection over Vnet peering to an ILB with two Apache Servers in the BE. NatGW provided soley for deployment of Apache Server
