From concept to MVP
As Product Design Consultant, I shaped the experience: turning emotion + vitals into something you can feel.


This is the work I'm proudest of but Voicari is under NDA, so I can't show the real product screens, health dashboards, or internal UX files I designed. What you'll see here is the thinking behind it: the problem, the decisions, and how I designed for three audiences and a system that's never 100% sure. If it feels light on screens, that's the NDA: not the depth of the work. Happy to walk through it privately.

Let's start the journey here
Before any screen, I had questions. Real ones. This is where the design actually begins.
- 01
How do I research a product that speaks for animals?
I can't interview the dog,so I researched both sides: the science of canine emotion and behavior, and the humans who'd read it. Domain research met real conversations with pet owners.
- 02
Who are we really designing for: the dog, or the human holding the phone?
Both, but not equally. The dog is the input; the owner is the user. The interface speaks to the human, on the dog's behalf.
- 03
What do pet owners actually need to feel about their pet?
Connected and reassured - not buried in data. They want "I understand you," not "here's a chart." So I designed for reassurance first, detail second.
- 04
And honestly: I'm a pet lover too, so what would make me trust this app?
Honesty. If the AI isn't sure, it should say so. I trust a product that admits uncertainty over one faking confidence - so I made the design transparent about what it knows, and how sure it is.
Answering these shaped every decision that followed.

Design is a conversation, not a handoff.
Voicari lived in the details.Real-time calls with founders, engineers, and domain experts, deciding together how to turn complex signals into something people trust.
I wasn't designing for one user. I was designing for three.
The same dog's signals mean different things to different people. Three audiences, three lenses on one product and the design had to serve all of them without picking a favorite.
The Owner
THE EVERYDAY ONE · EMOTIONLoving, worried, not an expert. Need: reassurance: "is my dog happy, or is something wrong?"
The Vet
THE CLINICAL ONE · VITALSPrecise, time-poor, evidence-driven. Need: accurate health signals they can trust and act on.
The Dog Trainer
THE BEHAVIORAL ONE · BEHAVIORPattern-focused, hands-on. Need: behavior over time to guide real training decisions.
To hold three very different needs into one calm, trustworthy moment.
What I owned.
Product Design Consultant, MVP stage. I shaped the core experience and owned the health feature — working directly with founders, engineers, and domain experts to take Voicari from concept to a testable product.

The daily-use feature, born under deadline.
The hardware was the heart of the MVP: some of the experience simply couldn't come to life without the device, and user review day was closing in fast.
So the CEO and I sat down and asked a sharper question: what can Voicari give people every single day? Emotion translation is powerful but for a busy owner, it's an occasional "let me check." We needed a reason to open the app daily.
That's where the health feature came from: something that quietly works in the background, analyzes over time, and gives owners a daily reason to care. I designed it to read as calm and clear first, detailed on demand, reassurance for the owner, precision underneath for the vet.
We built it, took it to user review, and the feedback was clear: people loved it. Voicari went from a "when I'm curious" app to a daily habit: the push notification they actually welcomed.
Emotion translation makes people smile. Health analysis makes them come back every day.
Dense health data, made calm.
The feature turns continuous signals into a single, reassuring read - a clear daily status up top, the detail a step underneath. Reassurance for the owner, precision for the vet.
Representative visual: not the actual product UI (under NDA).When AI can’t sure, the design shouldn't pretend it is.
Pretending otherwise would break trust the moment it's wrong. So I designed the interface to be honest about confidence: clear when it knows, careful when it doesn't. Designing for a probabilistic system is its own craft and it's exactly where AI product design is headed.
Validated & growing.
Users responded warmly to the health feature: the positive feedback validated the direction. And Voicari didn't stop there: it's now growing into its next phase, advancing the hardware that started it all.
Positive user feedback on health confirmed the direction; Voicari is now scaling into its next phase, with hardware development underway.
