A turnkey SDWAN platform designed so small businesses could connect their sites without needing a network engineer on staff. Originally a senior engineering project, later picked up and deployed commercially by a telecom integrator that kept running it as part of their offer.

Architecture: ZeroTier as the SD-WAN overlay handling the encrypted mesh between sites, MikroTik routers as the edge devices on each site (pre-provisioned to be plug-and-play), and a custom controller that owns the management plane through a dedicated REST API.

Edge firmware: flashed OpenWrt on the MikroTik units so the same image and the same ZeroTier client run everywhere - one provisioning path, one update workflow, regardless of the underlying hardware revision.

Controller: a deliberately lightweight central node that exposes the API the integrator's operators use to onboard a new site, push policy, manage members on the ZeroTier network, and monitor reachability. The whole point was to push the complexity to the management plane while keeping the controller itself simple enough that the integrator could operate and extend it without our team in the loop.

Why it mattered: classic SDWAN platforms (Cisco Viptela, Versa, Fortinet) are sized for enterprise budgets. This one shipped the same idea

• centralized policy, one overlay, plug-and-play edges - at a price point that a small business could actually buy.
