What I do

From raw source to executive dashboard

End-to-end coverage of the data platform — architecture, engineering and delivery.

Data Lakehouse Architecture

Medallion architecture (Bronze/Silver/Gold) on Delta Lake and Databricks, governed with Unity Catalog. A single, reliable, scalable source of truth.

ETL & Integration Pipelines

Automated, idempotent, monitored pipelines with Azure Data Factory, SSIS, PySpark and Python. From API and legacy database ingestion to the consumption layer.

Executive BI & Analytics

Power BI dashboards executives actually use — operational KPIs, semantic models and auditable metrics ready for decisions.

Cloud & Modernization

Migrating legacy data warehouses and processes to Azure and Databricks. Lower cost, better scale and new use cases unlocked.

Governance & Data Quality

Catalog, lineage, access control and quality validation. GDPR/LGPD compliance and data the business can trust.

Advisory & Enablement

Architecture assessment, tooling decisions and team training for self-service analytics — from technology selection to go-live.
