What I'm looking for

I’m open for freelance projects, especially remote work designing and shipping products across B2B and B2C SaaS.

At BigGo, I owned flows, specs, and UI for B2B and B2C products. For BIRSE, I proposed and secured official Built for Shopify certification, then owned the product end to end; it serves 500+ e-commerce clients and generates US$30K+ ARR.

I also designed BigGo Finance features including Ask AI, scheduled alerts, and usage billing, and led the 0-to-1 design of OAPhub after competitor research identified clutter as the main problem. I aligned OAPhub and Dive on one design system.

As a freelance UI/UX Designer and Indie Product Builder, I’ve designed products across e-commerce, AI, fintech, and industrial equipment. I built six interactive Web100 party apps solo with Claude Code, and I use research, play-tests, and clear specs to help teams ship products.
