Medallion Architecture Guide
Bronze, silver and gold layer responsibilities — what belongs where, and the boundary rules that stop silver becoming a second bronze.
Documentation
Reference guides,
written from practice.
Patterns I've shipped in production, documented properly. Publishing through 2026.
Auto Loader in Production
cloudFiles configuration for mixed encodings, repeated CSV snapshots, schema evolution and reset behaviour.
Unity Catalog Setup
Catalog and schema layout, volumes, access control and federated query design that scales past the first three teams.
Data Quality Expectations
Using pipeline expectations to track, warn or drop invalid records — and choosing which of the three each rule deserves.
Oracle RAC & Data Guard
High availability across 12c, 18c and 19c: when RAC earns its complexity and when Data Guard alone is enough.
PostgreSQL Sync Patterns
Lakehouse-to-operational synchronisation: snapshot versus continuous, schema evolution and downstream contracts.
OCI Storage Integration
High-throughput pipeline patterns against Oracle Cloud Infrastructure storage, with capacity and cost notes.
Well-Architected for Data
Applying the AWS Well-Architected pillars to data platforms specifically — where the generic guidance falls short.
