HappyDoc – Building a Complete Design Foundation from Zero in One Year

I joined HappyDoc as the company's first design hire. Two developers had built a functional AI scribe for veterinary clinics — but there was no brand, no design system, and no design process of any kind. In one year, I built the entire design foundation from scratch, alone — contributing to a product now trusted by thousands of clinics with 98% satisfaction across 1.2M+ appointments.

Senior Product Designer • First design hire • 2024 - Present

Role

Senior Product Designer — First & only designer

Scope

Brand, design system, product, mobile, marketing site

Team Structure

Solo designer embedded with product & engineering

Stage

Early-stage startup, high growth, fast sprint cadence

The Challenge

Design a coherent brand and product experience for a fast-growing startup — starting with no visual identity, no design system, no tooling, and no precedent. Everything needed to be created, decided, and shipped by one person, without slowing down an engineering team that was already in motion.

The Solution

• A complete brand identity — logo, mark, color system, and typography — built from the ground up.
• A scalable design system and component library used across web and mobile.
• A full redesign of the SaaS product and mobile app, replacing developer-built UI with a consistent, branded experience.
• The marketing website at happydoc.ai, translating the new brand into a public-facing product.
• Marketing creative assets aligned to the new brand for campaigns and outreach.

Discovery

Understanding the product, users, and gaps

With no prior designer to hand things off, getting up to speed meant doing it myself — scrappy, fast, and woven into the early weeks on the job.

Hands-on audit of every screen in the existing developer-built UI

Interviews with founders and internal team members to understand vision and constraints

Self-directed competitive research across vet AI and medical SaaS products

Ongoing feedback sessions with real veterinary clinics throughout the process

Brand

Building the HappyDoc brand from the ground up

HappyDoc needed an identity that felt trustworthy enough for a clinical environment but warm enough for a brand built around loving animals. I built it entirely from scratch — researching the space, exploring directions with AI-assisted variation, refining in Illustrator, and presenting through multiple stakeholder rounds.

Logo system — primary, horizontal, wordmark, icon, and sticker variants

Perry the mascot — a cartoon Australian Shepherd named after my own dog, with a spark above his ear signaling the AI is listening

Color system — Shadow, Max, Tropicana, and Blaze with full tint scales for product and marketing

Typography — Fraunces for headlines, Plus Jakarta Sans for product and body copy

Brand Guidelines v1.0 — the source of truth for every touchpoint that followed

Why It Mattered

At a fast-moving startup with one designer and a full engineering team, a scalable system wasn't a nice-to-have — it was the only way to ship consistently without being a bottleneck. Every component built once meant every feature shipped faster.

I used Untitled UI as the structural foundation and extended it with the HappyDoc brand — building a ~50-component Figma library that served both web and mobile, documented with specs and annotations for engineering handoff.

Design tokens — color, typography, and spacing mapped to the brand system

~50 components — Untitled UI foundations adapted to HappyDoc, plus custom components for product-specific needs (recording controls, SOAP note editor, AI assistant panel)

Figma-first handoff — engineers worked directly from component pages, no separate docs needed

Why It Mattered

Real clinics were using HappyDoc daily. A jarring overnight redesign risked losing the trust of customers who'd already adopted the product. The phased approach — brand first, then section by section — meant users experienced improvement, not disruption.

We introduced the new brand gradually — color updates first, then section by section — until every part of the product reflected the new design. Every core area was redesigned across both web and mobile.

Dashboard, appointment recording flow, SOAP note editor, Scout AI assistant

Practice insights, call capture, settings — plus full iOS & Android mobile app

Key improvements: clearer hierarchy, reduced clutter, better navigation, WCAG-compliant contrast, one-handed mobile usability for the exam room

Marketing

Taking the brand public at happydoc.ai

The existing marketing site predated the brand entirely. I redesigned the homepage from scratch in Figma — building a full conversion-focused narrative from hero to FAQ — then applied the new header and footer across the rest of the site as a consistent frame. Built collaboratively in Webflow.

Homepage designed end-to-end: hero, social proof, features, comparison, stats, reviews, pricing, integrations

New header & footer propagated across all pages for immediate site-wide cohesion

Remaining pages being updated section by section — an ongoing, living rollout

Process

Working as a team of one inside a team

Day-to-day I worked closely with our Director of Product — they owned the roadmap, I owned the design direction, and we moved fast because the lines were clear. Beyond that partnership I was embedded in engineering sprints, presented to founders at key milestones, and served as the creative resource for the broader business.

Figma as the single source of truth — specs, states, and annotations all in one place for engineering

Designed ahead of sprints so engineering was never blocked waiting on design

Marketing creative across social, email, sales decks, one-pagers, and event materials

Outcomes

What one year of solo design actually produced

A year in, HappyDoc looks and feels like a different company than the one I joined. The brand exists. The product is consistent. The system is scalable. And the numbers speak for themselves.

Complete brand identity — logo, Perry, color system, typography, brand guidelines

~50-component design system across web and mobile

Full SaaS product and mobile app redesign

Marketing website redesign at happydoc.ai

Full suite of marketing creative assets

What This Role Taught Me

Doing everything solo at startup pace teaches you to prioritize ruthlessly. The skill isn't doing everything well — it's knowing which decisions have long-term consequences and making sure those are the ones you get right.
