about me

Hi, I’m Kelsey! I’m a data visualization developer and creative storyteller based in New York. As a technical collaborator, I help communicate insights from data, enabling clients to tell their story in a way that will resonate with their audience.
How do you tell the right story in the best way?
Check out my presentation at Observable's 2024 Insight Conference where I go behind the scenes of a few projects to show how the magic happens when we collaborate beyond our roles!

"By anchoring on data, delight, and the human connections behind every project, Kelsey demonstrates the profound impact that thoughtful, well-crafted visualizations can have. It’s a reminder that data isn’t just numbers — it’s stories, people, and possibilities waiting to unfold."

McKinsey & Co.
At McKinsey & Company, I was tech lead for multiple full-stack web applications, web pages, digital twins and microsites. These are the public web pages that were designed by my colleagues at McKinsey's Data Visualization Lab then developed by me.
