I’m Effie! My journey began in an econometrics class at Rutgers: 30 students, one professor, and a chalkboard of equations. I was captivated by how math could amplify human cognition and reveal insights we couldn't see. That spark grew into a fascination with how data, modeling, AI/ML, predictive analytics and generative AI, push the boundaries of what we can understand and create. I'm a lifelong believer in data's power to transform decisions. I lead growth marketing and marketing analytics, focusing on systems integration and directly embedding AI and insights into workflows to drive measurable impact as Head of Growth, VP of Marketing Analytics, or Marketing Science leader. I’ve transformed businesses across finance, healthcare, and Big Tech. At AIG, I led a cross-functional team of 10, generating $200M+ while improving efficiency for 350+ underwriters. At Meta, I authored the playbook that drove a $99M+ retail market share shift through attribution modeling. At Viva Eve, I redesigned digital strategy and operations, embedding GTM strategy and marketing mix modeling (MMM) to deliver +150% ROAS, cut CAC by 50%, and improve lead conversion +38%. Across these roles, I’ve overseen multimillion-dollar marketing budgets and piloted AI-driven analytics solutions, using predictive models and automation to scale decision-making and improve ROI. I specialize in: Revenue Growth & GTM : +150% ROAS (Viva Eve) Market Expansion: $99M Share Shift (Meta) Cost Efficiency: -10% Media Spend, Flat Sales (StoneX) Customer Acquisition: -26% CAC (Viva Eve) Operational Efficiency: -90% Reporting Reduction (Viva Eve); -40% Submission Discovery for 350+ Underwriters (AIG) with SQL, Python, and R Lead Conversion: +38% Lead-to-Customer (Viva Eve) Highlight: a major retailer’s senior executive publicly cited my Direct Mail Share Shift work at Meta as a blueprint for digital transformation. WHY ME? I thrive at the intersection of marketing, data science, and business strategy—aligning teams through cross-functional leadership, budget accountability, and executive partnerships to drive growth. Excellence defines everything I do, and I let results speak louder than words. I’m always excited to connect with others curious about growth, digital innovation, & AI. If you’d like to exchange ideas or explore how analytics and technology can spark transformation, I’d love to hear from you!
