JP Fontelo | Digital Analytics & Data Instrumentation | New York City & Washington, DC
Get in TouchAvailable for consulting engagements. I work with small businesses and executive teams who need a rigorous analytics professional without the overhead of a full-time hire.
Audit your existing tagging, design or redesign your event taxonomy, QA the implementation, and work with your engineering team to instrument it correctly. I can also identify opportunities to enrich your analytics with additional data sources.
Dashboards, deep-dive ad-hoc analysis, and experiment design. I'll assess your traffic volume and technical setup before scoping any A/B testing engagement.
UTM taxonomy design, attribution modeling, Tealium implementation, and marketing pixel management. If you can't trust where your traffic comes from, you can't determine what it's worth.
Case studies and portfolio pieces.
Post-deploy validation of the hacker_news.full table against a 12-month baseline. Three-stage framework under time pressure: table integrity, event volume, and parameter capture.
Read Case StudyA worked example of a full instrumentation engagement: event taxonomy design, GA4 + BigQuery implementation, and dashboard build. Raw SQL analysis throughout.
A Looker dashboard tracking usage of the prediction tool and site analytics.
Applied data science and engineering built outside of work.
A logistic regression pipeline identifying mispriced sportsbook lines using Statcast data and matchup analysis. Built in Python with pybaseball, pandas, scikit-learn, and PostgreSQL. Functioning as both a live betting tool and a portfolio piece demonstrating rigorous analytics methodology.
