Medallion pipeline
Raw JSON in bronze, normalized Parquet in silver, scored signals in gold — each layer reproducible and idempotent.
Stratum
A quantitative data-lake platform with cryptographic provenance — from raw macro data to scored signals.
What Stratum is
Stratum ingests 30+ external macro and financial sources, refines them through a bronze → silver → gold medallion pipeline, and produces quantitative signals you can trust — every record carries cryptographic provenance back to its source.
Signals, not just data
Gold tables join across sources into domain signals, validated with walk-forward methodology.
Provenance by design
Every record is traceable to the source fetch that produced it.
Built on AWS
CDK-defined, multi-account, deployed through CI/CD with security guardrails.
