Clean, tested, documented transformations your analysts can trust
This service is for companies that have invested in data infrastructure but struggle with inconsistent metrics, duplicated logic, and undocumented transformations. If your analysts spend more time fixing data than analyzing it โ analytics engineering is the solution.
We build the transformation layer between raw data and analytics-ready datasets using dbt and modern analytics engineering practices.
Raw data is messy. Business-ready data is not. The gap between the two is where analytics engineering lives โ and it’s often the most neglected layer in the modern data stack. Without it, analysts write their own SQL transformations (with inconsistent logic), data quality issues propagate downstream, and nobody knows which version of a metric is correct.
We bring software engineering discipline to data transformations. Using dbt as our primary tool, we build transformation layers that are version-controlled, tested, documented, and optimized for analyst self-service. Every model has a clear owner, a clear contract, and a clear purpose.
We don’t just write SQL โ we design data architectures that make analytics scalable, maintainable, and trustworthy. Our work sits between data engineering and business intelligence, ensuring that analysts get clean, reliable, well-modeled data without needing to understand the underlying complexity.
We design and build dbt projects from scratch or restructure existing ones. Proper folder structure, naming conventions, materializations, and configurations โ set up for long-term maintainability.
We design dimensional models, staging layers, intermediate tables, and mart-level datasets. Clear separation of concerns, consistent naming, and business-friendly terminology throughout.
We implement comprehensive testing: schema tests, data quality tests, referential integrity checks, and custom business logic validations. Tests run automatically in CI/CD โ broken data never reaches production.
We write descriptions for every model, column, and metric. Your data catalog becomes a living, searchable resource that analysts can trust and navigate independently.
We set up continuous integration and deployment pipelines for your dbt project. Pull requests trigger automated testing, and approved changes deploy seamlessly to production.
We configure semantic layers (dbt Semantic Layer, Looker LookML, or custom solutions) that define metrics, dimensions, and business logic in one place. Consistent definitions across every tool and dashboard.
We train your analysts and analytics engineers to own and extend the dbt project. Pair programming, code reviews, workshops, and documentation โ so your team becomes self-sufficient.
