What I Do

At the core, I help companies use data and AI to make smarter decisions and build products people trust and love.

Product & Behavioral Analytics

I analyze how users interact with digital products, and why. My focus areas include funnel analysis, event tracking, cohort analysis, experimentation, and behavioral segmentation.

I work with product and growth teams to uncover what drives engagement, retention, and activation, using those insights to help build products people love, use, and return to.

Data Strategy & Infrastructure

I help startups and established companies build strong data foundations that support fast, confident decision-making. This includes defining north-star metrics, setting up data pipelines, organizing analytics-ready data, and creating reporting workflows that scale as products grow.

Business Intelligence & Reporting

I design scalable reporting layers and stakeholder-ready dashboards that make insights accessible across product, operations, and leadership.

My goal is to ensure teams can trust their data, track what matters, and align on priorities, so they can make confident, data-informed decisions.

Machine Learning & AI

I help product-led companies leverage machine learning and applied AI to build intelligent product features, optimize user experiences, and scale data-driven decision-making across global markets.
