Square Handheld
(2025)
Interface
Art Direction
In 2025, Square launched its first handheld point of sale. With a dip slot, bar code scanner, and camera, Square Handheld offered our small but mighty team the opportunity to take a holistic design pass at our hardware OS and the multi-sensory commerce experience. Beyond the interface, I helped push forward a sonic design and haptics solution, with our partner Audio UX. Alongside a talented 3D design partner, I art directed an on-device single cam feature tour, helping bolster feature awareness, usability, and trust.

Tap to Pay is Square's first ever contactless, free-to-get-started product. I had the pleasure of leading the experience design of this new technology across iOS and Android. To improve education efficacy in a way that was context considerate, I worked closely with brand to bring creative into the product. Tap to Pay has quickly become a key revenue driver for Square, helping small businesses across the globe take card payments with just their phone.

Stellar is a protocol and non-profit organization aiming to create equitable access to the global financial system through blockchain technology. I directed a full brand redesign from the client side, orchestrating brand strategy, stakeholder alignment, and an RFP process that led to a meaningful partnership with Kurppa Hosk. I collaborated closely alongside their team from concept through reviews and refinement to create an identity that distinguished itself from a prevailing scifi aesthetic in the space through a return to functionalist graphic principles and a measured application of boldness.

As the founding designer of WhoCo, I was responsible for designing a brand, product, and team for a web application and data platform aimed at improving hiring efficacy. Reflecting the team's desire to combat bias in hiring, I translated product notions around intentional abstraction into a shape-based illustration language that permeated the product, and wider usage guidelines. As a team, we shipped a wide variety of web based software products and hiring features with a constructivist but optimistic design language.

At Headspace, I led a ground-up app redesign, building a team of eight exceptional designers and working across a wide range of mediums and contexts. As a tight knit team, we expanded and adapted a highly distinctive brand language to fit a digital context, at scale, earning App of the Year by both Apple and Google in 2017 in the process. The redesign drove meaningful business performance, laying the groundwork for a near decade of growth.
