ETL / ELT Modernisation
"Replace fragile jobs with tested, documented code"
Migrate fragile legacy ETL jobs to dbt, Airflow, or cloud-native orchestration — without disrupting the dashboards and consumers that depend on them.

Inventory of jobs, dependencies, owners, and downstream consumers.
dbt adoption
Models, tests, documentation, and CI — modular and review-gated.
Airflow / Dagster / Prefect
Orchestration migration with backfill and replay support.
Strangler migration
Run new alongside legacy until parity is proven and traffic moves.
Cost tracking
Per-pipeline warehouse credit and orchestrator compute visibility.
Knowledge transfer
Documentation and pair-programming to onboard your team.
Working lifecycle
Inventory
Catalogue every legacy job with owners and downstream usage.
Pick path
Decide replace, refactor, or retire — per job.

Strangler pattern with side-by-side validation.
Decommission
