Juniper networks, built by hand or built as code.
I'm Bill Wester, an independent network engineer based in Washington State, with 25 years on Juniper, F5 and Infoblox and a co-developer of the Terraform provider for Juniper Apstra. I do the work myself, with old-school craftsmanship: careful, documented and done right the first time. You work directly with me, on US time and in plain English, with no hand-offs to someone you've never met.
Core practices
Hands-on Juniper
Firewalls, switches and routers, configured, fixed and migrated at the CLI.
- Juniper SRXVPNs that won't come up, chassis clusters, upgrades, policy cleanup and firewall migrations onto SRX.
- Juniper EX and QFXCampus and data center switching on EX and QFX, from Virtual Chassis to EVPN-VXLAN fabrics, Mist-managed or CLI.
- Juniper MistThe whole Mist platform: wireless design, EX switching and campus fabrics, SRX WAN Assurance and Marvis.
- Juniper MX and M seriesEdge, core and peering routing on MX, plus migrations off aging M series routers.
Apstra and infrastructure as code
The same networks, defined in Terraform, kept in Git and deployed through a pipeline.
- Apstra and EVPN-VXLANData center fabrics designed and run through Apstra, automated with the Terraform provider I helped write.
- Network automationTerraform, Ansible, Python and Go for networks, written by someone who has shipped a production Terraform provider.

Case study: a multi-gigawatt AI campus network, from an empty site
For Phase 1 of Galaxy Digital's Helios campus I built an Apstra-managed EVPN-VXLAN fabric deployed entirely from Terraform, automated Infoblox DDI, a Mist-managed out-of-band network, and diverse dark-fiber paths with Ciena.
