Christina Day - Designer & Developer

A bit about me

I'm Christina, a product designer and front-end developer based in Oakland. I've spent the last decade working with teams to build digital products—everything from early prototypes at startups to enterprise platforms used by thousands of people.

I like to work at the intersection of design and code. I think about implementation while I'm designing, and I care about user experience when I'm coding. It tends to make things move faster and work better.

I build design systems with React, prototype with real data, and create interfaces that developers can actually implement. This hybrid approach helps teams ship better products faster.

I create brand identities that feel authentic and memorable

I created HackerDAO's complete visual identity—from logo to custom illustrations—building a brand that helps Web3 developers feel like they belong to something bigger.

I build design systems that scale—and I code them myself

I didn't just design ZeroCater's component library—I built it myself with React, reducing development time by 60%. This hybrid approach creates design systems that actually work in production.
