I’m Don Cruver, a software engineer with about 30 years in the industry. I work in data science, AI, and software integration.
I believe in data sovereignty—owning your infrastructure, your data, and your tools. This site documents the projects I build to make that happen.
I’m also drawn to questions of epistemology—how we determine what’s real in an environment full of noise, manipulation, and competing narratives. That interest is what led me to build Signalscope.
Some things I’m currently working on and happy to discuss:
- Local AI hardware and software — Running large language models on secondhand datacenter GPUs
- Signalscope — Detecting coordinated information operations and narrative campaigns
- Health Tracking — Self-hosting personal health metrics (ketones, blood pressure, labs)
- Homelabbing/Self-hosting — Proxmox, k3s, OPNsense, ZFS, and owning your own infrastructure
- Second brain / PKM — org-roam, ox-hugo, and building a personal knowledge system in plain text
