Brass Tacks

Over 10 years designing where complex systems and real user need overlap on the Venn diagram. Adobe (Marketo), Upwork, Meroxa, Teamshares, T-Mobile.

AI products need designers who can hold the product together when the rules don't exist yet. That's been my whole career.

Selected work

Case Study

Vye Health

Building the patient experience, end to end

Turned vibecoded flows into a coherent patient journey — and a process that made each sprint faster than the last.

Case Study

Vye Health

Teaching a design system to vibecode itself

Built the token architecture and Claude Code skill that let anyone on the team generate 60%-polished prototypes without a designer in the room.

Case Study

Teamshares

Payroll reporting

Saving Teamshares ~$3.1M annually without adding or subtracting headcount.

Case Study

Teamshares

A hiring engine for a company of companies

The design system that survived an acquisition

Built Sky's design system from the ground up. Patterns contributed upstream to Adobe Spectrum.

Case Study

Marketo / Adobe

733% adoption increase through trust-first migration

Users were resistant to disruption. That was a design problem.

Case Study

Meroxa

Pivoting from a builder to a data observability platform

How a discovery in research forced a pivot that opened doors for Meroxa.

Perspective

Designing for people who live in the product

On cognitive load, multi-persona platforms, and what full-day software demands from a design system.

Perspective

Design Systems Built to Travel

On building token-first systems that propagate intent from Figma to code — and why the gap between design and implementation is still a design problem.

Perspective

The Skill Layer

On writing AI skills that implement design systems — and what a design system has to become before a skill can carry it faithfully.

About

I'm Dante. Staff Product Designer based in Irvine, CA. I think in systems first, then UI — which means I'm as likely to redesign the brief as the interface.

Thirteen-plus years in enterprise SaaS, internal tooling, and healthcare platforms. I started my career writing front-end code and never fully put it down. These days that looks like building machine-readable design systems, designing with Claude Code and Figma MCP, and figuring out what AI-native design actually means when it has to ship.

I've also mentored designers across both product and creative work throughout my career — it's one of the most fulfilling parts of what I do. There's something about giving back the same way others poured into me that I keep showing up for.
