Finding the leak in a luxury funnel.

As a Regional Operations intern, I built an end-to-end funnel analysis spanning Awareness → Consideration → Purchase → Retention, synthesizing paid-media, web-analytics, lead, and CRM data across thousands of monthly leads and 5 channels to give regional marketing leadership a single view of where the funnel leaked.

I diagnosed a double-digit percentage decline in lead-to-sale conversion and isolated Brand Website as the highest-converting channel, converting at roughly 1.6× the rate of dealer sites, surfacing it as the highest-ROI reallocation target. Then I reframed a suspected “traffic problem” as a purchase-intent problem: visits rose while lead submissions fell, with a sharp year-over-year paid-traffic decline tracing to the spring tariff onset.

Digital Growth Strategy 2025

Multi-platform digital growth strategy for Bethesda Bagel

A full digital plan for Bethesda Bagels, an established DMV bagel shop (est. 1982): a PageSpeed & Semrush audit, high-intent Google Search, dayparted Meta/Snapchat social, and a LinkedIn catering play, with each channel matched to a distinct buyer, plus A/B tests and a GA4 measurement framework. (MKTG-663 Digital Marketing, American University.)

Ops Analytics 2025–26

Samsung Process Innovation: KPI dashboards & AI automation

Procurement runs an internal funnel of its own: 500+ onboarding requests a year across 32,000+ SAP vendor accounts. I built the team's first KPI dashboard, surfaced a compliance-review gap nobody had measured, and cut onboarding cycle time 40%. Then I built a multi-agent AI tool that cut manual processing time 95% and automated 75% of reporting, as much an adoption and change-management problem as a technical one: I trained non-technical staff to self-serve, protecting continuity ahead of Samsung's Texas relocation.

Full-Funnel Campaign · Academic 2024

AWAY luggage: full-funnel campaign concept

Graduate coursework at American University: a full-funnel concept for AWAY luggage. MRI-Simmons data in Tableau showed that among Asian consumers, women already prefer AWAY (index 115 vs 90) while men lean Rimowa (84 vs 111). That set the target: young Asian millennial men. Allocated a $1M budget across YouTube, Instagram, and LinkedIn with a KPI mapped to each funnel stage.

Smithsonian NMNH: reaching community-college students

Graduate marketing consulting project for the Smithsonian National Museum of Natural History. My team owned the community-college segment: I ran the environmental analysis and primary research, analyzed it in SPSS and Tableau, and built a segmentation, targeting, and brand-positioning strategy around the pillar the audience wasn't feeling: accessibility.

Predictive Analytics · Forecasting 2024

Product diffusion forecast: Bass model on iPod

Reconstructed 13 years of iPod unit sales from Apple's 10-K and 10-Q filings, fit a Bass diffusion model via regression to estimate market potential and the innovation/imitation coefficients, forecast sales through 2025, and characterized life-cycle and Q1 holiday seasonality, with time-series and ML alternatives recommended for sharper forecasts.

Tools I built

Analytics anyone can use.

I build self-serve R Shiny tools so non-technical marketers can run rigorous experiments and predictive models on their own; faculty recognized them as replicable resources.

Experimentation Live app

A/B Test Sample-Size Calculator

Answers the question every experiment starts with: how many people do we need? Enter baseline conversion rate, minimum detectable effect, power, and significance level, and it returns the required sample size per variant and the planned test duration from your weekly traffic. Handles one- and two-tailed tests.

Predictive Analytics Live app

Logistic Regression: First-Year Value Optimizer

A predictive pricing tool: fits a logistic regression on customer response to price, promo, and messaging, then projects first-year customer value across the full price grid (net of installation and acquisition costs) and surfaces the price × promo × message combination that maximizes it. Supports single cases or batch CSV upload.

About

Marketing-trained.
Analytics-driven.

I earned my MS in Marketing with a specialization in Marketing Analytics at American University's Kogod School of Business, a 4.0 GPA on top of a communications degree. I'm as comfortable writing the story as I am building the model behind it, and predictive analytics was my strongest suit in the program, from logistic regression and pricing models to Bass diffusion forecasting.

Since then I've worked as a data-and-process analyst at Samsung and in regional operations at Audi, where I saw how much growth hides inside a well-instrumented funnel. Now I'm focused on the work I trained for: lifecycle and growth analytics, experimentation, and turning messy data into decisions that perform, whether that's a campaign, a retention play, or a new-business pipeline.
