Sarah Tomaszewski

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

Currently designing multi-user workflows, tools, and scalable systems at Happily where I lead product experiences for both event specialists and their clients. I focus on creating intuitive, thoughtfully structured solutions that simplify complex operations. Outside of design, you’ll usually find me exploring new places, playing tennis, or reading with a matcha in hand.

Event Website Builder

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

Event Marketplace Experience

Launched the client-side of Appily—a marketplace for hiring event production specialists—focused on intuitive browsing, seamless hiring, and clear communication.

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.

HealthTech App Concept

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.
