Lexi Barry | Data-Driven Product Leader

Transforming insights into strategy through analytics, storytelling, and product thinking

πŸ’‘ Portfolio Overview

I built this portfolio to showcase my data storytelling, product thinking, and analytics strategy skills. Using fully synthetic data, I created a mock wellness technology brand called Vital Metrics β€” a connected ecosystem featuring a smart scale, wellness ring, and companion app.

This project demonstrates my ability to translate data into actionable business narratives through end-to-end analytical design. Within this portfolio, you’ll find:

πŸ“Š Six interactive dashboards highlighting user behavior, retention, product engagement, and performance metrics

🐍 Python scripts demonstrating data manipulation, transformation, and insight generation

🧠 Executive insight deck modeled after a real-world client presentation, emphasizing storytelling, clarity, and strategic recommendations

🧩 Case study deck outlining research frameworks, analysis design, and experimentation logic

πŸ”’ Private work section tailored for specific companies, showcasing adaptability and confidentiality

Together, these projects reflect how I approach analytics as a data-driven product leader β€” connecting insights to business strategy through thoughtful design, clear communication, and measurable impact.

About Me

I’m a data product manager and analytics leader passionate about transforming complex data into clear, strategic narratives.
