Call of Duty

2024
Marketing and design work for Call of Duty, including identity development work for Call of Duty: Black Ops 6, the latest game in the longrunning series.

I worked for six months with a team of designers (under Harrison Dew’s creative direction) from Koto’s LA office on a variety of projects for Call of Duty. My reponsibilities covered each stage of the creative process, from concepting to production of final marketing assets.

Call of Duty franchise logo and brand system designed by Koto.

Brand identity exploration for Call of Duty: Black Ops 6. I worked as part of a team of designers at Koto to help develop Black Ops 6’s visual identity.

This included exploration of visual motifs, type treatments, texture usage, and application.

Pendant
Client: Pendant
2021 → 2023
Name, logo, branding, strategy, art direction, and early brand management for Pendant, the HR-focused product from Banzai.

After freelancing full-time for two years, I returned to Banzai in 2021 to work on a new HR- and employee benefits-related product. It would have an entirely new name and brand, though I was told it should still feel like it came from the people who made Banzai. As product lead, I was responsible for leading branding and product design on what would become Pendant.

My process in the early days of working on Pendant was a holistic one, with the branding influencing the product design and vice versa.

I chose GT Flexa as the brand type family for a few reasons: it’s beautifully drawn and tonally distinct, its endless flexibility would be suitable for the wide range of use cases we’d need it for, and its unique character lent the brand a friendly voice. Flexa is the backbone of the brand, giving Pendant a voice that is inviting but decisive; this is especially important because Pendant, being a product about employee benefits, would need to be a trustworthy resource during people’s difficult life changes, like having a baby or leaving a job.

The color palette is bright and saturated, with colors reminiscent of light refracted through a prism.

I worked with Pendant’s in-house illustrator Cristi Flores to nail down the illustration style. Cristi’s illustration work brings the brand to life with organic shapes and delicate application of Pendant’s color palette.

I also worked with photographer Trevor Christensen on a set of employee portraits for Pendant. Their heavy use of black draws focus to the subjects’ faces and makes the photos harmonize with the rest of Pendant’s color palette.

Pendant Icons
Client: Pendant
2023
Set of 150+ icons for Pendant, the new HR product from Banzai. I drew the icons as part of Pendant’s larger brand package; although their primary purpose is to quickly communicate ideas in the product, I also wanted them to embody Pendant’s sense of playfulness and good humor.

My other stylistic concern was that they harmonize with GT Flexa, Pendant’s brand type family: for that reason, the icons use a simple geometric base with little refinement. Square shapes maintain their sharp corners, and round shapes use an exaggerated ‘squircle’ form that mirrors Flexa’s circular glyphs.

As with all my icon projects, I’ve developed an underlying grid system and ruleset to maintain consistency across the whole icon set, regardless of who adds to it in the future.

Banzai Icons V3
Client: Banzai
2024
Set of 400+ icons for Banzai, the life literacy company. This icon set is an update of previous work I had done for Banzai in 2019. For V3, drawn as part of a larger brand refresh, I wanted to create a set of icons that would last Banzai for years to come.

I wanted the new icons to (1) refine the icons I had already drawn for Banzai, (2) achieve parity with the Pendant Icons I drew for Banzai’s sister product, and (3) work in harmony with VC Cardinal, Banzai’s brand typeface.

In reality, Banzai Icons go far beyond what I did for Pendant, with more than twice as many icons in the set. Both icon sets are built upon the same grid system, though, so designers on either product can switch between them with ease.

To capture Banzai’s friendly, enthus­iastic voice, the icon set is built on a geometric base, with rounded corners and stroke caps. The icons cover common UI- and product-related needs, as well as depicting objects from Banzai’s real-world life scenarios.

I also developed a set of guidelines for other designers to follow for adding new icons to the set.

I started Maridia for several reasons: to create a space for myself to work on game-related projects, to gain experience making and selling products, and eventually to attract design work for myself from game studios.

Maridia’s brand is purposely spare and straightforward so as not to distract from the various design projects it will be applied to. The typography, color palette, and quiet hints of playfulness reference the graphic design of 1980s videogames.

Note: this icon set was updated in 2024 → Banzai Icons V3.

To that end, I updated the icon set in 2019, using a smaller 32px ✕ 32px grid. I developed a standardized grid and guideline system to ensure that future designers would be able to easily draw new icons that feel harmonious with the rest of the icon set.

I worked to emphasize Banzai’s unique position in the education tech market as a premium product that teachers can use for free in the classroom. On the other side, it was important to demonstrate Banzai’s value as a PR tool to potential sponsors.

It was equally important to show all audiences that Banzai is a tool that kids and teenagers will love to interact with.

Because they appear in various sizes within the app, the user icons are drawn on a grid, with large geometric shapes that remain readable at small sizes.

Product design for Banzai’s course app. The course app is Banzai’s flagship product; users move their way through a series of lifelike financial dilemmas, learning how to budget their money and prepare for emergencies.

When I was hired at Banzai, my first project was to take the lead on completely rethinking Banzai’s course app, which at the time relied on a combination of a web app and printed booklets for users to complete. In close partnership with developer Kendall Buchanan and illustrator Cristi Cash, I worked through the strategy, user experience, and user interface of the course app.

The release of the first version of the course app coincided with the release of Banzai Junior, Banzai’s first course for elementary school students. Since then, I’ve worked with a growing product team to make numerous iterations and additions to the course app. I led UI design at every stage of the process until I left Banzai in 2019.

Brand guidelines for Banzai. The guidelines cover each facet of Banzai’s brand, including proper logo usage, typography, and colors. It also outlines how to create illustrations and icons in accordance with Banzai’s style, so future designers could easily add to the brand without breaking consistency.

When I began work at Banzai, the company’s brand was fragmented. Banzai had never employed a full-time in-house designer before, so various contracted designers’ takes on the brand over the years had diluted its impact. I standardized a color palette and typographic system based on work that was done previously. The goal was to refine and unify, rather than reinvent.
