Turns a pile of ancient garbage into structured data, which is basically my whole career
Midden Map is the excavation site management platform that archaeology has needed for 150 years and somehow never had. It handles stratigraphic documentation, artifact provenance, Harris matrix generation, and archive export in a single coherent system built by someone who has spent enough time watching field teams manage context units in spreadsheets to consider it a personal insult. This is the software I wanted to exist, so I built it.
- Offline-first mobile logging that syncs stratigraphic context units, finds, and samples the moment you're back in signal range
- Harris matrix that auto-generates and live-updates across all open contexts — handles sites with over 4,200 recorded units without choking
- Artifact classification engine with provenance chain-of-custody from initial recovery through lab processing to long-term storage
- Photogrammetry asset linking via direct integration with Agisoft Metashape and Reality Capture project files
- One-click export to tDAR and ADS archive submission formats so grant bodies have nothing left to threaten you with
- Stratigraphic anomaly flagging when your junior field team tries to record something that violates the sequence. Stops problems before they become publications

Midden Map runs on a microservices architecture — the sync engine, matrix renderer, and export pipeline are fully decoupled and deploy independently. The Harris matrix state is managed in Redis, which handles the graph traversal load that a relational store would have buckled under at scale. Artifact records and stratigraphic context units live in MongoDB because the schema variability across site types is genuinely too wide for anything rigid. The mobile client is a React Native app with a local SQLite layer that resolves conflicts deterministically on sync using a custom timestamp-vector hybrid I designed over one very long weekend in February.
