The position002

A dashboard is only as good as the system underneath it.

I build and repair the entire path: authenticated extraction, durable raw data, orchestration, transformations, semantic contracts, serving layers, and the visual surface where someone finally makes a decision.

Representative systemsBuilt + designed

D—01

Authenticated extraction

Turn difficult source systems into durable inputs.

Connector patterns that use browser sessions only where login and MFA require them, then move to direct authenticated HTTP, hardened parsing, original-response preservation, immutable publication, and fail-closed drift detection.

Production orchestration

Pipelines built for backfills, failures, and change.

Dagster and dbt systems that coordinate incremental syncs, partitions, backfills, tests, source-scoped schedules, and safe production canaries across warehouses and serving layers. Exceptions stay visible and recoverable instead of becoming manual cleanup.

D—03

Decision-grade semantics

Keep source truth, model logic, and dashboard math distinct.

Semantic and reporting layers that preserve grain, confidence, and financial boundaries; reconcile conflicting systems; and publish through Cerebro, Tableau, Looker, embedded dashboards, and purpose-built analytical tools.

Operating standardsNon-negotiable

Built to survive contact with reality.

01

Raw evidence survives

Original inputs and immutable artifacts remain available when the model or parser changes.

02

Grain is explicit

Orders, receipts, consumers, accounts, and events are never blended into a convenient but misleading total.

03

Live means verified

Release, orchestration, serving, and the final rendered surface are checked as one delivery path.

Operational software

Replace spreadsheets, manual handoffs, and fragile workarounds with software built around the operation.
