Summary
Shelly Resurreccion is a data analytics lead with 11 years of experience and 8+ years focused on data science, currently leading analytics at Critical Mass from Calgary. She combines hands-on modeling (time series, XGBoost, classification) with pragmatic engineering—building ETL pipelines into AWS Redshift and migrating version control and documentation systems—to turn insights into production-ready solutions. Shelly has driven measurable business impact for major brands (Nike, BMW, Pepsi), cutting media spend inefficiencies by 80%, improving creative health by 38%, and boosting lead forecasting efficiency by 60%. Equally comfortable advising executives and mentoring teams, she translates complex models into actionable dashboards and test-and-learn experiments that inform strategy. Her background in computer science, digital communications, and HarvardX data science training gives her a rare blend of technical rigor and storytelling for non-technical stakeholders. Outside the obvious metrics, she’s repeatedly bridged marketing and engineering workflows—running A/B tests, campaign analytics, and system migrations—to ensure analytics deliverable longevity and adoption.
