Northgrain is led by a data engineer who still works close to production code, reviews, data models, and deployment details.
About
A founder-led data agency for teams that need the work done properly.
Northgrain Data helps teams build reliable pipelines, dbt models, warehouse foundations, analytics workflows, and AI-ready data systems.
How the agency works
Senior technical work, without the agency fog.
We join the messy middle of data work: inherited dbt projects, unclear warehouse models, fragile pipelines, reporting pressure, and AI ideas that need usable data underneath.
Data engineering and software engineering background
Hands-on across Python, SQL, dbt, Airflow, Snowflake, BigQuery, AWS, GCP, Docker, and CI/CD
Works close to implementation, review, and handoff
Open source
dbt-doctor came from the same problems we see in client work.
Static analysis and health checks for dbt projects: docs, tests, stale models, schema drift risk, and DAG maintainability.
dbt-doctor
A CLI for catching issues that usually show up late in review: missing tests, weak docs, stale models, and hard-to-maintain dbt DAGs.
