Sarah Tomaszewski

Hi, I’m Sarah! A Product & UX/UI Designer crafting thoughtful experiences that bridge creativity and functionality.

Currently leading end-to-end product design at Happily, partnering with product and engineering to turn operational complexity into scalable, intuitive tools for internal teams and customers. Outside of design, you’ll usually find me exploring new places, playing tennis, or reading with a matcha in hand.

Empowers event creators to craft beautiful, functional websites with customizable design and RSVP tools, streamlining how events are planned, shared, and managed.

Created Spot, an iOS app connecting pet owners with trusted vet care. Focused on simple navigation, a warm visual tone, and an intuitive way to find medical and pet care services.

Design System Foundation & Visual Language

Designed the user interface for Simple Thai, an app for learning Thai from English. Focused on intuitive navigation, interactive lessons, and a visually engaging learning experience.
