Patrick Stowe Jones

Product designer and architect building experiences at the intersection of digital, AI, and the real world.
I bring the systems thinking, attention to detail, and craft of an architect to digital product, shaping AI-first experiences that feel human and usable so we can engage more fully with the world and each other.

Most recently Director of Product Design at Walmart, I’m currently an independent designer collaborating with leading companies like Gusto, McDonald’s, and Brick.
 
AI-powered social mapping


Maps help you find brunch. Plot reimagines your block. I'm exploring AI maps by buidling an app for geospatial discovery and collaboration around neighborhood change.

Walmart Auto Care Center

I led the redesign of Walmart’s Auto Care experience as it lagged competitors and sat outside the company’s connected ecosystem. Our mandate was to rebuild the core journey while redefining service end to end. The work unfolded in two phases: rebuilding the fundamentals, then expanding them into a connected, proactive system that understands the customer’s car and supports service over time.

#1 Revenue growth
+500% Service bookings
+35% GMV lift
+5% Market recapture



Walmart Connect


Advertisers using Walmart Connect had to switch between seven disconnected tools to manage different kinds of campaigns leading to friction and fragmentation. I led the effort to unify them in a single platform and build coherence through shared patterns, components, and a consistent way of working across. This created the foundation for AI-powered retail media through flexible work flows, extensible insights, and data fludity.

Carrier Fleet

Led the creation of Fleet, a prototype design system for rapidly developing spatial services across Carrier’s business. Applied across teams to prototype and validate new building and cold chain services, it launched with Abound, Carrier’s flagship healthy buildings platform, and established a shared foundation for how complex systems are designed, tested, and brought to market.

$250M First year revenue
-85% Engineering load
5 months Prototype to launch
Faster Onboarding and governance



FedEx Mobile


Limited communication with customers forced couriers into reactive workarounds and led to missed deliveries. I designed timely interventions in existing shipper and recipient flows that enable real-time coordination and shift the system toward proactive, reliable service rather than customer service triage.

-560k Tons/yearReduction in CO2
< 356,000/day Reduction missed deliveries



Lifemap

Explored how spatial data can capture everyday life by designing Lifemap, a prototype social mapping app.

People move through places but lack a way to record and share what those places represent—moments, relationships, and experiences.

Lifemap turns location into a layer of memory, enabling people to mark what matters and share it with others—framing location as a foundation for connection and social discovery.



Thrive


Aging adults often want to remain in their homes but face increasing isolation and loss of independence. Partnering with AmFam, my team designed Thrive, a coordinated service that connects people to the tools, support, and community they need to adapt and stay engaged, reframing aging in place as an active, supported experience.
