Ex-Western Union | 🏆 Award-winning Analytics Lead | 14+ years of expertise If you've experienced analytics that produce complexity, not clarity — dashboards full of charts that are technically correct but practically useless, financial models that are messy to maintain and disconnected from the decision that needs to be made — I fix that. After a decade leading analytics at a global firm and consulting to SME clients across 7 countries, I've learned that the only metric that matters is whether the work changes a decision. Every model and dashboard I build starts from a use case: a specific business pain, a specific person who needs to act. The chart only earns its place if it triggers something. NOTABLE RESULTS → Fully automated operational reporting at a global fintech — Python & SQL models auto-streamed to a production Power BI dashboard, eliminating a manual reporting cycle entirely → Predictive churn model for a B2B SaaS client: 11% retention improvement within two quarters → Unit economics model for an e-commerce startup: uncovered 7% profit leakage from a mispricing no one had caught WHAT I BUILD · Financial models — 3-statement, scenario analysis, unit economics, pricing, build-vs-buy. Structured so a CFO can stress-test it without calling you. · Power BI / Tableau dashboards — from raw, messy sources to a live dashboard your team opens without being told to. · Data models & ETL pipelines — clean schemas, documented logic, refresh cycles that don't break when a source changes. · KPI frameworks & scorecards — metric definitions agreed on before they're visualised, not after. HOW I WORK Diagnostic first — I won't quote until I understand what you actually need. Then scoped deliverables, fast iterations, documentation included. No sprawl. Free diagnostic call available. That's where we figure out whether this is the right fit — and what the output should look like before we start.
