I'm Humayun Khan — I design and build digital products.

For over a decade, I've been designing digital products across healthcare, education, and enterprise. Now I build them too — with AI. I work across the full stack using Claude and Cursor as my primary development tools, shipping interfaces in React and Next.js while sweating the design details.

Currently, I'm at Practice with Joy, building Shopify for NPs — the platform that lets nurse practitioners launch their own primary care practices. Before that, I built marketing automation tools with AI at Reputable Health, and led the Android-to-React-Native transition at ClassDojo.

I also build my own products. Cortex is a spaced-repetition learning platform. All My Parts is an IFS therapy app with AI-analyzed journaling. QueryCat was a marketplace connecting authors with literary agents — bootstrapped to $300 MRR and 1,000+ users.

Before consulting, I was Product Manager at Xello and Design Lead at Roadmunk (acquired by Tempo) and Tiny Hearts (acquired by Shopify). I started my career in growth marketing at Shopify. I'm also a published author — my book Wrong Side of the Court was published by Penguin Random House.

Available for AI product builder roles, founding designer positions, or consulting engagements. Based in Montreal, open to remote.
