Hi, I'm Shin! I'm a designer, maker, tinkerer, and problem-solver—and most importantly, a homeowner myself—passionate about bringing comfort, efficiency, and beauty into living spaces.
With a background in information science and design, I specialize in turning complex data into engaging, actionable insights. My goal is to help homeowners make smarter energy decisions to transform insights into practical improvements.
My experience spans UX design, digital tools, and product development, including my time as a startup co-founder. I believe energy efficiency isn't just about saving money—it's about truly understanding how your home works so you can take control of its performance and comfort.
When I'm not helping clients, you'll find me traveling, swimming, playing tennis, skiing, cooking, or singing with two choir groups in the East Bay and San Francisco. Let's make your home more comfortable, efficient, and enjoyable!
