Stella Peng

Stella Peng is a designer who builds across design, tech, and things in between. She's pursuing a Master of HCI + Design at the University of Washington, with previous design experience at TikTok working on social experiences and on new ways AI can fit into the design process. Before that she studied and worked in Michigan, shipping 0 to 1 and 1 to 10 products with early-stage startups and an accelerator.

Selected work

• Circle Status — A smart lamp and companion app that turns passive outage detection into active community connection. Built in 15 weeks in Michigan's Integrated Product Development program, launched at a 200-person trade show, and sold 264 units in three days.
• AskSia — An AI study companion for university students. Research-led redesign of the core learning flow, grounded in usability testing and design analysis of the existing product.
• Philo Design System — A design system for an e-commerce MVP: a token-based foundation, 50+ documented components mapped to React Native, and UI templates that cut the design-to-dev cycle to two weeks.
• TikTok — Product design internship work on social experiences and on new ways AI can fit into the design process. Case study coming soon.
