dbt, SQL & Transformation
We help you turn raw landings into tested, documented marts — with grain, tests, and owners — so a new engineer can follow the model and finance can defend the number.
The work
How we help
A warehouse without a modeling layer becomes a pile of SQL. dbt estates without grain become three definitions of revenue. We design, build, and refactor transformation so certified tables have a meaning a controller can restate.
We use dbt Core or dbt Cloud in your repo and CI. We do not require a full rewrite when a scoped refactor of the domain that is breaking close will do.
When this is the engagement
dbt or a SQL mart already exists, definitions have forked, or a new domain needs models finance can defend.
Contracted and invoiced by Havilah Technologies LLC. Delivery in your warehouse and your git.
- 01Establish or repair grain: what one row means in the fact, and which keys the mart is allowed to join.
- 02Build incremental models, snapshots, and tests that fail on the real business rule — not only on not-null.
- 03Document models, exposures, and contracts so Tableau, Power BI, or an agent cannot silently invent a fourth definition.
- 04Refactor inherited dbt projects: packages, CI, naming, and the models that actually feed close.
- 05Leave a modeling standard your team can extend without calling us for every new column.
Typical work
What an engagement looks like
01
Modeling standard
Layers (staging, intermediate, marts), naming, tests, and ownership so the project is a system, not a folder of SQL.
02
Certified marts
Domain marts — finance, operations, commercial — with tests and documentation aligned to how the business decides.
03
Incremental strategy
Insert/overwrite, merge, and snapshot patterns matched to volume and late-arriving data, not a default that burns credits.
04
Estate refactor
Triage of an inherited dbt project: what to keep, what to isolate, what to rebuild, with hours attached.
What you receive
Deliverables
- Certified marts with tests that fail on the real grain
- Incremental and snapshot strategies matched to the workload
- Documentation a new engineer can follow
- A refactor plan that does not require boiling the ocean
Capabilities
In scope
- dbt Core and dbt Cloud modeling, packages, and CI

Data Engineering & Pipelines
We design and build the ingest, CDC, and orchestration that move ERP, CRM, files, and APIs into a warehouse operations can run.
Analytics Architecture & BI
We define and deliver the metric layer so Tableau, Power BI, or Looker reports the warehouse — not a fourth version of revenue.
Data Integrity, Quality & Governance
We put tests, lineage, owners, and reconciliation in place so accuracy holds after delivery — at close, audit, and in regulated programs.
