I build for collectors.

I’m Quyen. I’ve been collecting for as long as I can remember — sneakers, trading cards, art, vinyl toys, sports memorabilia, anything with a story behind it. The portfolio you’re looking at is Volume 03 of my career — a collection of work built for the people who chase the same pieces I do.

Volume 01  ·  Graphic design

I spent the first decade of my career as a graphic designer, working with creative agencies on corporate identities, websites, print and digital marketing collateral, and exhibit booths. Commercial craft for commercial brands — the kind of work you don’t notice unless it’s done badly.

Volume 02  ·  Cybersecurity UX

In my early 30s I crossed over into software. I joined NetWitness, a startup cybersecurity company, to help with a rebrand. My work on the marketing side caught the attention of the CTO and senior engineers, who asked me to join the engineering team and redesign a suite of security applications. I didn’t have UI design experience for software at the time, but I took the leap — it was the best decision of my career. A decade in enterprise product design followed, across KoolSpan, RSA, and HYAS.

Volume 03  ·  Collectibles

I couldn’t stay away from the thing I love. In 2020 I co-founded WANTD with my friend Rick — originally a sneaker inventory app, which evolved into a live-stream shopping marketplace for sneakers and streetwear. We went through Y‑Combinator’s Winter 2022 batch and raised $1.3M before I rolled off. Today I’m Head of Product at Mantel, the social platform we’re building for collectors across every vertical — sports cards, comics, coins, toys, watches, and beyond. I lead product strategy, design the UX, and write production code alongside the engineering team using Claude Code and Cursor.

Being a collector gives me a starting point most product teams don’t have — I know what collectors want before the research confirms it. Shipping it is a different conversation: user need meets business metric meets what engineering can actually build. Domain empathy just shortens the loop between the first two.
