Designing experiences people actually use.

About Me

I'm a Product Designer with 4+ years of experience designing across the full stack of a product — from the pixels on screen to the systems that hold them together.

As the sole designer at Strivve I built a scalable design system from the ground up and led the complete redesign of their web and mobile products — creating a unified design language that now serves as the foundation for every digital product the company ships going forward. Before that, at Firstech LLC, I led UI/UX and visual design for consumer hardware and mobile software that reached tens of thousands of users, working directly alongside engineers to ship three major product launches.

Most designers think in screens. I think in systems — how a design decision in one place creates a ripple three flows downstream, how a component built wrong today costs a sprint later, how a launch isn't a finish line but a feedback loop.

I'm drawn to complex products with real constraints: hardware, mobile, cross-platform. The harder the problem, the more clearly good design thinking shows.Currently open to full-time Product Design roles at teams that ship.
