I find the problem worth solving, design it, and build it. Most recently All My Parts, an AI journaling app I shipped solo. Before that, a decade and a consumer app used by 50M people.

The automation layer for a network of nurse practitioner clinics: booking to a visit-ready chart with no staff touch, and a note that's finished before the patient leaves.

A prenatal and postpartum telehealth app for a YC startup: four kinds of specialist on one balance of credits, and booking that starts with who you'll see.
Humayun is the rare designer who can take a fuzzy, high-stakes problem and turn it into something clean and shippable. He led the design of our COVID-19 assessment platform under real deadline pressure and made it look easy. Any team would be lucky to have him.
Humayun took our MVP functionality and updated brand guidelines to create a design system and product experience we could be proud of, while keeping the mothers we work with firmly in mind. He'd be a valuable addition to any early-stage start-up.
Humayun is one of those rare people who can design and build the whole thing. On an early team that's a force multiplier: he figures out what's worth building, then ships it, while most are still writing the spec.
Between projects I build things for myself: apps, prototypes, small experiments. Some grow into real products with paying users, some stay tests. Either way, this is where I try a new tool or idea on my own time.

I'm Humayun, a product designer and builder based in Montreal, working remotely since 2020. Shopify, ClassDojo, and a string of healthcare and AI startups, then independent, designing and shipping products end to end.
I work across the whole stack of a product: framing the problem, the core flows, the interaction and visual detail, and the front end when building it is faster than describing it. A decade in product and design is behind that, including sole designer on a consumer app used by 50M+ people.
What I care about most is taking something complicated and making it feel simple, and the details that decide whether an experience feels right.
Always happy to talk about product, design, and hard problems.
