Medallion pipeline

Raw JSON in bronze, normalized Parquet in silver, scored signals in gold — each layer reproducible and idempotent.

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 exact source fetch that produced it.

Built on AWS

CDK-defined, multi-account, deployed through CI/CD with organization-level security guardrails.

Bronze → Silver → Gold

Stratum refines raw data through three medallion layers — each one reproducible, idempotent, and traceable to its source.

  1. Bronze Raw JSON, exactly as fetched
  2. Silver Normalized, typed Parquet
  3. Gold Scored, joinable signals
Every record stays traceable to the exact source fetch that produced it.
