The Work

I build Python, Django, SQL, and dbt analytics tools that transform operational data into reliable, decision-ready outputs — KPI dashboards, BI-ready exports, tested dbt models, and data-quality-checked reporting across FX and FinTech domains.

Principle Practice
Source-first Inspect and validate before transforming
Test-driven dbt tests and Django TestCase on every layer
Claim-safe Documented boundaries — no overclaiming
Evidence-based Reviewer-verifiable outputs at every stage

"Revenue rank #1 doesn't mean strongest product. Birthday Classic drops to margin rank #4 after waste-adjusted margin — a finding reproducible across three implementations."

The Evidence

Metric Value
UK Operational Experience 15 years
Daily Cash Volumes Managed £30,000
UK Agents Supported ~800
Automated Tests — CareerFunnel 828
dbt Data Tests — bakeops-dbt 26
dbt Models — staging → mart 7
