UmbraCore
Technologies, Infrastructure & Black Sky Events –
What we work on
Technologies
Private AI that runs on hardware you own: local models, retrieval over your own documents, and automation that doesn’t ship your data to someone else’s cloud.
Infrastructure
Virtualization, storage, networks and backups, designed by someone who has run them for global plants, a county 911 center and multi-site clinics.
SHTF Solutions
Plans for the bad day: offline knowledge, failover links, backups that have actually been restored, and communications that don’t depend on a cell tower.
From the lab
Going live: a lab staging site and a production Linode
The UmbraCore site is now public. I edit and approve changes on a container in the lab, and one button publishes them to a hardened server… Homelab
Three rebuilds later: what stuck
Memory layers that poisoned themselves, a runtime swap that fixed ‘model’ crashes, and why one GPU can’t do everything. AI Stack
Why I’m pulling every inbox home
One local store for every personal account, with scanning and local AI triage. MailHub
Who’s behind it
UmbraCore is the independent lab of Dennis Cary, an IT operations, infrastructure and security leader with more than 25 years across global manufacturing, county government and public safety, and healthcare, and a U.S. Air Force veteran.
