MARCUS PROIETTI · PRODUCT DESIGNER

I like the part where we figure out what’s worth building.

I ask a lot of questions. I sketch, prototype in code, and work through the messy parts with the people building it.

ABOUT ME

THE STORY BEHIND
THE DESIGN

Senior product designer, 14 years across developer platforms, e-commerce, and fintech. Hands-on: I design the flows, build the component libraries, and prototype in code. I'm strongest early, before anyone has decided which problem is worth solving.

I love engineers.
I love pizza.
I love Halloween.
I love lamp.
I love solving problems.

Experience

FEB 2026 – AUG 2026 · 7 MOS

Ricon — Product Design Consultant

Early-stage startup focused on connected digital experiences, collectibles commerce, and interactive storytelling.

  • Partnered with an early-stage startup to define product strategy, user experiences, and design direction across a connected digital ecosystem.
  • Designed and prototyped three interconnected products: a collectibles marketplace, a central platform, and an interactive storytelling experience.
  • Developed reusable design foundations, interaction patterns, and functional prototypes, bridging product strategy, UX design, and front-end implementation.
OCT 2021 – APR 2026 · 4 YRS 7 MOS

360 Finance — Lead Product Designer

  • Founding designer: Designed contractor-led financing as a product while the business model was still being worked out.
  • Designed and shipped three connected portals (contractor sales, homeowner application, internal ops) so a contractor's sale, a homeowner's loan, and the back office resolved into one transaction.
  • Designed the contractor portal for independent operators who couldn't be required to use it, so adoption had to be earned through the workflow itself.
  • Built the component library from zero; the product still runs on it.
SEP 2019 – OCT 2021 · 2 YRS 2 MOS

Pantheon — Product Designer

  • Owned design and research for Integrated Composer, a platform feature that brought PHP dependency management into the dashboard as one-click updates — turning a command-line workflow into something a site owner could run without touching Composer directly.
  • Designed the platform's static site generation product end to end, from concept through developer documentation.
  • Defined interaction patterns for developer-facing tooling, working directly with engineering.
JUN 2018 – SEP 2019 · 1 YR 4 MOS

Madison Reed — UI/UX Designer

  • Designed across three sides of one business: the consumer e-commerce checkout, the Colorist app used by staff in Color Bar locations, and the operational tooling behind those locations.
  • Redesigned the Colorist app end-to-end — scheduling, consultations, and inventory in a single tool used during client appointments.
  • Started the Madison Reed design system and maintained it as the shared reference across teams.
NOV 2014 – APR 2018 · 3 YRS 6 MOS

Auction.com (a Ten-X company) — Product Designer

  • Designed the company's first Android app, extending a desktop-era auction marketplace onto mobile.

  • Applied the company-wide rebrand across web and mobile.
