Revenue matched to the cent across four dashboard pages while margin did not: $333,573 of cost sat on 3,056 order lines that never shipped. The KPI diff that exposed it now fails the build. Its dbt marts run on Snowflake. A Streams/Tasks pipeline reconciles 94,758 lines after late arrivals, duplicates and corrections; a Snowpark judge agrees, with access checks and a resource monitor recorded.

Supply Chain Analytics — dbt
Finance and Ops stop arguing about revenue, because there is one versioned definition. Every build names the downstream models a change touches, and the same project builds on DuckDB, Databricks and Snowflake to the same totals. Airflow’s scheduler runs it nightly in CI. An AWS Athena run over private S3 data reconciles 32 warehouse measures to an independent Python calculation, with a 10 MiB scan cap.

Finance Decision Models in Excel and Power BI
Portland General Electric’s H1 2026 revenue was $100.9M below an independently modelled plan, split into weather, price and usage, in Excel and Power BI on public filings. Beside it, a distributor model for channel economics and working capital, that distributor’s budget cycle with three linked statements and a 3+9 reforecast, and a lululemon DCF traced to SEC filings.

At month-end, 8 of 60 account-periods certify themselves, 9 go to a named reviewer and 43 are blocked. No approval is invented to make the close look finished.

Pricing & Costing Analytics
The list price is not the price: 18.2% of it never arrives. This shows which points to go and get, and routes each price change to the person who must approve it.

Before it recommends buying more, it checks whether spare stock elsewhere in the network already covers the gap, and what each service target would cost a year.

Legacy-to-Fabric Migration
The move from SSIS/SSRS to Fabric waits on a row-for-row GO/NO-GO gate across 107 artifacts, and the tests break the data on purpose to prove the gate catches it.

Ask Your Data
Ask 71 tables a question, typed or spoken, and see the SQL behind every answer. On a 58-question test it answers 46 correctly, gets none wrong and refuses 12 rather than guess.

Canada Wildfire Risk
Forecasts for 753 cells, refreshed twice daily. First 36 graded target days through 28 October 2026: ROC-AUC 0.734 (95% CI 0.696–0.770). Top-10% capture is 28.7%; its advantage over the baselines remains uncertain.

FINANCIAL CRIME · ANOMALY DETECTION
Transaction Monitoring
A flat $10,000 rule finds 38 of 60 planted cases. Five explainable rules plus an anomaly model find all 60 while alerting on a third fewer entities, and each rule is mapped to FINTRAC’s indicators and reports. Customer names are screened against Canada’s real sanctions list, scored on a held-out half. KYC rates every customer and traces beneficial owners through holding companies, and two rules run on a Kafka stream on Kubernetes in CI. A privacy assessment classifies every published data element and records the controls still needed for real clients.

MEASUREMENT · CAUSAL INFERENCE
Marketing Attribution & Incrementality
Last-touch gives “direct” a quarter of all conversions; its true share is 1.9%. Six attribution models chase a known answer and none finds it. A geo holdout does, so the synthetic budget plan is calibrated on that. Separately, real GA4 data in BigQuery exposes $54,525 of duplicate or invalid purchase-event revenue and a checkout tagging-order defect.

RECOMMENDER SYSTEMS
Customer Recommendation Engine
The two-stage ranker lost to plain collaborative filtering, 81.2% to 84.9% recall@10, so the simple model ships. A proposed, pre-registered randomized pilot would measure commercial lift; no online lift has been established.
