Sebastián Narváez

AI-Native Product Designer

I design and ship. I take products from Figma to production with AI coding tools. 10+ years crafting B2B and B2C products. Now building AI-native experiences end to end.

I'm also a music nerd, so I built this synth. Go on, play with it!

Featured Work

How I Work with AI

A look at how I actually design and ship with AI. I use Claude Code to build real frontend from my designs, and I build my own tooling, skills and guardrails so a small team moves fast without dropping quality. This is the part most designers can't show.

Voice AI Agent

Designing a conversational, state-aware voice agent for a call center. I mapped the branching flows and human-in-the-loop controls, built a working prototype, then made the call to discontinue it after evaluating its limits. A study in AI-native UX and product judgment. (Client work, password-protected.)

Case Tracker

AI-native risk detection for a legal CRM. I designed the experience that surfaces at-risk cases and clients before they escalate, and shipped it to production. It enabled proactive outreach to thousands of clients. (Client work, so this case study is password-protected.)

About me

Hi, I'm Sebastián, a product designer with 10+ years of experience crafting digital products for B2B and B2C across many industries. What makes me different today: I don't just design, I ship. I'm the sole designer on a small engineering team building an AI-native product, and I take my work from Figma all the way to production with AI coding tools.

I bring three things most designers don't have together:

Design craft. Interaction design, UI/UX, design systems, research and UX strategy, always centered on real user needs.

Technical fluency. I've coded since I was 15. I ship production frontend (React, TypeScript) and build my own AI tooling and guardrails, so I bridge design and engineering instead of just handing off.

Business and product sense. A Master's in Business Innovation and hands-on product management experience, so what I design is viable, not just beautiful.

Both my parents have been teachers their whole lives, so a bias toward learning and mentoring runs in the family.
