# Projects

Every project Nathan has documented, one file each, with a line on what it covers. Dates, role, event and figures are not repeated here: they come from the typed site data, which is prepended to each project document. Dates marked approx. in that data come from GitHub repo creation dates; hackathon dates come from the event or Devpost.

## Flagship and featured

- [Campus](/knowledgebase/projects/campus.md): What Campus is, how its LMS sync, hybrid retrieval and audited 20-tool agent work, and its test and usage numbers.
- [NixOS homelab](/knowledgebase/projects/homelab.md): How his two NixOS hosts are defined, what the self-hosted AI stack runs, how Hermes Agent profiles change the config behind approval, and llama.cpp on flow.
- [AWARE](/knowledgebase/projects/aware.md): How AWARE runs vision, audio and a small LLM on one Arduino UNO Q, and how plain-English commands become deterministic rules.
- [CareBridge](/knowledgebase/projects/carebridge.md): The CareBridge rural care platform from Spark 2026 (overall 3rd), built by a team; the repo is a teammate's (liamma06/Spark).
