Nicholas Pillsbury, Staff Business Intelligence Engineer at Webflow
Seattle, Washington

Nicholas Pillsbury is a Staff Business Intelligence Engineer at Webflow. His journey into the data world began when his strong proficiency in Excel led him to volunteer with a Business Intelligence (BI) team at work. As the data grew too complex for spreadsheets to handle, Nicholas pivoted to Tableau, teaching himself by deconstructing the work of others and finding inspiration from the DataFam.

Outside of work, Nicholas is an active member of the Tableau community, driven by the belief that no request for feedback should go unanswered. He participates in community challenges like #GameNightViz, #MakeOverMonday, IronViz, and more. On Tableau Public, Nicolas gets inspiration from other vizzes but also from research papers where he can see alternative ways to visualize the same data. Nicholas views data as inherently fun and strives to break down the silos that often isolate data experts. Currently, he is channelled into the IronViz season, using the breadth of high quality submissions as fuel to revisit his older projects and upskill them.

Connect with Nicholas on Linkedin and Tableau Public.
