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 — self-hosted models, inference infrastructure, retrieval pipelines, and workflow automation — architected with the same rigor we bring to the network underneath it.
jNode Platform
We build and maintain jNode, a network integration platform that connects estates with overlapping IP address space — no re-addressing, no endpoint agents, no vendor cloud. Learn more at jnode.app.
Who We Are
A women-owned boutique agency
SGA Tech LLC is a women-owned engineering firm built around an elite group of network and AI inference architects. We take on a small number of demanding engagements so each one gets senior attention from design through operations — you work directly with the architects doing the work, with no layers and no handoffs.
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
Day 1 reachability across overlapping IP estates
When organizations merge or integrate networks, overlapping IP addresses turn integration into business delay. jNode is a focused network integration platform that creates reachability between estates with conflicting address space — without re-addressing, endpoint agents, or forcing traffic through a vendor cloud. It sizes address translation around the DNS records actually in use, forms an encrypted WireGuard mesh between appliances at each network boundary, and coordinates DNS and routing from a single control plane. Built for mergers & acquisitions, disaster recovery, and multi-cloud and regulated environments.
SGA Tech develops jNode and provides implementation and ongoing support for the teams that run it. Explore the platform at jnode.app.
