Product & UX·UI Designer — California, USA

Design that
actually ships.

I'm Gonzalo — a product designer and founder of Delvir. I own the full arc of a product: research, UX, and pixel-level UI, then bring it to life in SwiftUI and Next.js. The result is design that survives contact with the real world — 15+ shipped iOS and web products across social, health, and fintech.

Dos Juntos / Couplet

Lead product & UX designer — 0→1, on the App Store

An AI relationship coach that gives couples a weekly health score and gentle, personalized guidance drawn from their real conversations. I designed the full experience: a low-friction onboarding, a sensitive chat-import flow, the weekly score, an ongoing coaching chat, and a subscription + partner-invite plan — then localized it end-to-end into Portuguese for Brazil. The hardest problem here wasn't screens; it was earning trust in an intimate context.

Promoflow

Product & brand designer

Done-for-you promo videos, generated from just a URL. I designed the brand and the conversion-first marketing site — the story, the funnel, and the "paste a link, get a launch video" moment that makes the offer click.

VeteranCalc

Product & UI designer — complex data

A VA disability rating calculator plus a premium AI report — the same experience on the web and as a native iPhone app. I turned a genuinely confusing benefits formula into a calm, guided flow, designing for clarity and trust around numbers that affect people's livelihoods.

Restu

Product designer — dense data made clear

A report-only credit tool that pulls all three bureaus — Equifax, Experian, and TransUnion — side by side and flags the errors between them. I designed the comparison view and the compliance-first flow so users can spot discrepancies at a glance without wading through legalese.

Real-world social

QRForce

Product & UI designer

A zero-friction "I need you now" signal for teams, friend groups, and families. I designed the one-swipe summon that pings your whole crew at once — a time-sensitive alert that breaks through Focus and silent — wrapped in a bold, high-contrast dark UI with no feed, no logins, no noise.

How I work

I don't hand off a pretty file and hope. I design the whole thing — and then I build it, so the vision that ships is the one that was designed.

01

Start with the problem

Real user context and real constraints first. The best interface is often the one you don't have to draw.

02

Design in systems

Type, color, spacing, and components as a system — so the product stays coherent as it grows.

03

Ship & learn

I take it all the way to production and iterate on what real usage reveals. Design isn't done until it's live.
