L Dante Guarin — Product Designer · Greater Los Angeles
Product design that helps startups ship and scale.
I partner with pre-seed to Series B teams as a hands-on product designer and fractional design lead — turning fuzzy ideas into shipped, systemized product.

What I do
Design that moves with your stage.
Product Design (0→1 & beyond)
End-to-end product design — from discovery and flows to polished, buildable UI your engineers can ship fast.
Design Systems
Scalable component libraries and design tokens that keep a growing team consistent, fast, and on-brand.
Fractional Design Leadership
Part-time design direction: set the vision, build process, and level up your team without a full-time hire.
Prototyping & Validation
Interactive prototypes to test with real users and de-risk decisions before you invest engineering time.
How I work
A calm, senior process built for speed.
01
Understand
Get sharp on the users, the business, and the constraints before touching pixels.
02
Design & iterate
Move fast in flows and prototypes, validate early, and refine toward a shippable design.
03
Ship & systemize
Hand off clean specs, capture patterns in the system, and stay close through launch.
AI-native practice
AI as a design multiplier, not a shortcut.
I fold AI directly into the design process to codify guardrails in your design system and compress the distance between idea and production. The result: fewer inconsistencies, faster iterations, and more room for senior judgment where it matters.
01 / Guardrails
Guardrails in the system
AI helps me audit patterns, generate token sets, and document rules so your design system enforces consistency instead of relying on tribal knowledge.
02 / Velocity
Accelerated product design
From brief to high-fidelity concepts in a fraction of the time — exploring more directions, testing ideas early, and shipping to engineering faster.
03 / Judgment
Senior judgment in the loop
AI handles the repetitive work so taste, strategy, and product intuition drive every decision — never automated away.
