Hey! I'm Sean Kesterson, a Senior Product Designer based in Brooklyn, NY, focused on helping early-stage startups scale through thoughtful UX, system-driven UI, and collaborative design practices.

Over the last decade, I’ve partnered with brands like Apple, MasterClass, and Yield Guild Games, delivering high-impact digital products across consumer, education, and Web3 industries. Whether I’m leading the design for a mobile app, building design systems, or streamlining a product’s user flow, I bring a blend of strategic thinking and hands-on execution to every project.

I also run my art practice: Alimo.

My experience spans:

• Product Design (Mobile & Web)

• UX Strategy & User Flows

• Design Systems & Components

• Brand and Visual Design

• Collaborating with Engineers & PMs

I work remotely (and locally in NYC), often embedding directly into product teams to move fast, iterate smart, and ship with confidence.
