Boutique network and AI engineering. We design, secure, and operate the infrastructure that runs your business — across cloud and on-prem.
See what we do
Network Engineering
Architecture, deployment, and operations for routing, switching, and software-defined networking — unifying cloud VPCs and on-prem fabric into one coherent, well-documented network.
Network Security
Segmentation, firewalls, VPN and zero-trust access, and hardened edge design. Security is built into the topology from day one, not bolted on after the fact.
Enterprise AI Deployment
Practical, private AI in production — from self-hosted models and retrieval pipelines to workflow automation — deployed with the same rigor we bring to the network underneath it.
jNode Platform
We build and maintain jNode, a management platform for modeling, provisioning, and operating network infrastructure at scale. Learn more at jnode.app.
Who We Are
A small team of senior engineers
SGA Tech LLC is a boutique agency. You work directly with the engineers doing the work — no layers, no handoffs. We take on a small number of engagements so each one gets senior attention from design through operations.
What We Do
End to end, cloud and on-prem
- Network architecture & design reviews
- Cloud and hybrid connectivity
- Firewall, segmentation & secure edge
- Private & enterprise AI deployment
- Automation & infrastructure as code
- jNode implementation & support
Why SGA Tech
How we approach the work
- Senior engineers, hands on the keyboard
- Documentation you can actually use
- Security designed in from the start
- Vendor-neutral, right-tool-for-the-job
- Built to hand back, not lock you in
The jNode Platform
Model, provision, and operate your network from one place
jNode is our management platform for network infrastructure — a single source of truth for how your network is modeled, deployed, and maintained. SGA Tech develops jNode and offers implementation and ongoing support for teams that run it. Explore the platform at jnode.app.
