I’m a product designer working at the intersection of hardware and software. Whether it’s a machine interface, mobile/web app, or a physical product, I design experiences that put people at the center of innovation.
My background spans physical and digital domains, enabling me to conceive and execute holistic solutions across mediums. I hold a BS in Product Design (HCI focus) and an MS in Mechanical Engineering from Stanford, where I specialized in physical product design and manufacturing.
Currently, I’m part-time at BrewBird, where I design user experiences across machine workflows and service operations.
I'm especially drawn to opportunities that connect the digital and physical.I’m open to new collaborations and roles across product, interaction, or experience design. Please feel free to reach out!
