I build data products that make management reporting easier to trust. The work here follows one synthetic Operations Review Service from the first business question through data checks, transformation, semantic modelling and the final review decision.
The examples use synthetic records and need no employer data, client data or private credentials.
Start with the Operations Review Service architecture. It defines the decision, service requirements, controls, risks, ownership and evidence expected from the reporting route.
The operational data quality engine applies that control thinking to a Python quality gate. It reads CSV or DuckDB data, runs a versioned rule policy and writes an exception register, quality report and run manifest.
The analytics engineering service mart takes the reporting logic into dbt. It contains contracted dimensions and facts, explicit SLA rules, effective target matching, reconciliation tests and a checked incremental event load.
The Power BI KPI model completes the route with a source controlled PBIP project. Its TMDL model contains 11 tables, 31 measures, 10 relationships and dynamic service area access. The PBIR report contains two pages and 10 bound visuals.

Each repository has a short review route, reproducible local commands and GitHub Actions. Main branches require pull requests and successful CI checks. CodeQL, dependency audits, secret scanning, push protection and private vulnerability reporting are enabled across the four repositories.
The examples are deliberately honest about their limits. The Python and dbt projects run locally rather than on a managed production platform. The architecture is a proposed service, not an implemented estate. The Power BI source passes automated model and report checks, but Windows Desktop acceptance and rendered screenshots remain open until they can be produced from the same reviewed commit.
