I design complex products—and build the working software that proves them.

My career spans product strategy, interaction design, user research, technical prototyping, and production software—including work at Google, Yahoo, Walmart Labs, and Kohl's.

Selected work

Judgment, systems, and shipped software.

Three projects showing design judgment becoming a tested interaction, a coherent system, and working software.

01 / Ecommerce

A simpler mini-cart at Kohl's

A crowded confirmation moment was interrupting shoppers at the point of highest intent. I reduced it to one clear message and two next steps.

Senior product designer. I owned the design direction and partnered with product and engineering to test it in Adobe Target.

Generated $25M in annualized incremental revenue in A/B testing.

See how the simpler interaction won

The original crowded Kohl's mini-cart — Before / too many competing jobs

The simplified Kohl's add-to-cart confirmation overlay — After / confirm, then choose

The enterprise product attribute management interface — Category rules became a visible, maintainable system that merchandisers could operate directly.

02 / Enterprise systems

Turning tribal knowledge into a CMS system

Product rules lived across spreadsheets, side documents, and one person's memory. I modeled the hidden logic and turned it into an interface.

I led system modeling and interaction design with engineering and merchandising.

Category teams could manage rules without an engineer in the room.

See how the system was untangled

03 / AI-native product

Afterword makes the blank page disappear

Journaling breaks down when writing feels like work. I made voice the starting point, then designed the reflection system around what people already said.

Independent product designer and engineer across the product thesis, interaction model, privacy architecture, and native iOS rebuild.

A voice-first, encrypted iPhone product with search, weekly reflection, and journal chat.

About Marco

Design and engineering are one continuous product decision.

My career spans staff-level product design, UX engineering, technical prototyping, and AI-native product development. That range lets me move from an ambiguous problem to a working system without losing the product intent.

I am looking for staff-level IC or hands-on leadership work where product judgment and engineering execution belong in the same role.
