Most data is noise. I find the one number that changes the plan.
I'm Bryan Duffin, a data engineer and analytics consultant with 15 years across marketing and data. I've led DataOps and GTM Analytics for enterprise software companies, run growth for startups, and run my own crowdfunding campaign. I build the pipelines, models, and reporting systems that turn raw data into decisions people actually make.
Work that moved a number
Every piece starts with a business question and ends with a decision. These are samples of real work, rebuilt here as interactive dashboards.
Identity resolution
48,117 identities unified for a service contractor, and a probabilistic layer that reconnected 89% of the pipeline value a global enterprise's CRM never saw. Same discipline, two scales.
Attribution recovery
Warehouse attribution took a contractor's paid-revenue visibility from 8.8% to 26.5% of won revenue, and stage-level data-driven models re-priced every channel's credit against the linear baseline for an enterprise funnel.
Value-based bidding
A BQML model prices every lead before sales touches it. Top-decile leads convert at 33x the bottom, so Google bids on modeled value instead of raw lead counts.
The questions matter more than the tools. These are the ones I reach for most.
Somewhere in your data sits an answer that's overdue.
Tell me what question you can't answer today. I'll tell you what it would take to answer it for good.
