Systems we’ve written into being
A selection of platforms we designed and built from the data model up — event-driven settlement, a double-entry ledger, telemetry at fleet scale, schema-driven analytics. Each one shipped as typed, observable infrastructure-as-code.

- 11 ms
- Balance drift
- provably 0
- Northwind Energy2024Illustrative
Telemetry for half a million devices, in real time
