About

Coaching 11U volleyball taught me that mastering fundamentals allows you to break the rules strategically. I approach product design the same way. Understanding user mental models and design principles deeply, and then knowing when to challenge conventions and repurpose ideas to create breakthrough (seemingly novel) experiences. I believe technology should bring people together, not isolate them. I focus on creating interfaces that feel personal and trustworthy, especially in AI, where users need to feel safe and understood. I know how to move fast, think strategically, and ship products that users love. In my first year of product design, I taught myself design, led two product teams, and won four awards. I am no stranger to taking initiative or working independently, having spent the past two years working in stealth AI startups as a founding designer. My approach combines behavioral science with startup grit, ensuring every interaction aligns with both user mental models and business goals while minimizing friction in AI adoption. You can find me browsing on Superme.ai or reading Medium/Substack articles on growth, behavioral science, and accessibility out of the office. I solve the problems that keep you up at night (because it keeps me up too): • Making complex interactions feel effortless • Designing for users who don't understand your product yet • Bridging the gap between engineering and user needs • Creating design systems that scale with your growth Teamwork & Play! As the person behind 16 designers' hackathon wins and 100+ student breakthroughs, I create environments where we address underserved markets, challenge conventional thinking, build for simplicity, and sequence complexity. Whether you need someone to bridge design and ML engineering, conduct AI usability research, or advocate for responsible AI practices, I am your design ally. Looking for my next adventure with innovative startups, AI companies like Claude, Grok, Gemini, or OpenAI, or forward-thinking product teams eager to integrate AI.
