About

With 16+ years of experience, I am passionate about driving tangible impact for organizations through data. I specialize in building and scaling data science and analytics functions that drive business outcome, influence product strategy, and accelerate company growth. With experience spanning Nextdoor, LinkedIn, Pinterest, and Meta, I’ve built and led teams that transformed data into actionable insights, optimized decision-making, outcome-driven data products, and rigorous internal processes. These fueled expansion of every company I've been a part of - through IPOs and beyond. As examples, I've driven projects that doubled the rate of user acquisition at Nextdoor, doubled MAU at Pinterest, and enabled growth of a brand new initiative that became the fastest growing business unit at LinkedIn. I achieved these outcomes by attracting and growing the best talents, developing data-aware cultures, and forming tight partnerships across business stakeholders. I thrive at the intersection of strategy, experimentation, and execution - helping companies turn data into a competitive advantage at scale.
