Selected public projects

A selection of technical projects using synthetic or sample data, with inspectable source, setup instructions and documented limitations.

Project Engineering work Source and evidence
Contoso Forge Deterministic retail data pipelines, Bronze/Silver/Gold transformations, multiple execution engines and dbt reconciliation. Extends SQLBI's Contoso Data Generator V2, retaining upstream attribution. Quick start · Forge source · Dated execution evidence
DiagramCloud Local architecture modelling, nested views, authored explanations, evidence links and static exports. React and TypeScript. Run locally · Tests · CI
DataPass MosaicStudio Browser analytics workbench and source SDK with DuckDB-WASM, TypeScript/Python contracts and reusable technical views. Alpha; local packages and deployed applications have separate release status. Quick start · Contracts · CI
SparkLab simulator Educational FastAPI service combining real DuckDB queries with a model of Spark stages, shuffles and compute metrics. Simulation results are not real Spark-cluster benchmarks. API and setup · Example requests · Tests

Professional focus

  • BI and analytics: SQL transformation and modelling, Power BI semantic models, DAX, reporting and optimisation.
  • Data engineering: Python/PySpark, Databricks, Microsoft Fabric, dbt and reproducible data workflows.
  • Software and cloud: Azure data services, typed application contracts, automated checks and developer tooling.

I use AI-assisted tools in selected development workflows. The linked code, design decisions and verification records show the implementation and its limits. Test results apply to the source revisions they identify.
