How I work

  • Sculpting digital products

    When designing digital products, you have to understand how the material works—its physics and its chemistry. You can design in pixels but you have to build in bytes. A designer who studies how it works—and stays close to the material—designs better products, faster.

  • Composing and decomposing design systems

    A design system is primitives bonded into compounds, then taken apart and reshaped when the work demands it. Good systems compose and decompose—they hold together under pressure and stay legible when you pull them apart. The job is to keep finding that balance. And ultimately a design system is a people problem—it lives or dies on the education and relationships you build with the designers and engineers using it every day.

  • Move fast, learn things

    Ship the minimal lovable product, then watch how real people use it in real life. Listen, research, ship again. Prototypes hallucinate—real users don't, and the research that actually corrects you only starts after the thing is in someone's hands.

Kind words from the past

  • “Kevin did an excellent job embedding himself within the engineering team. He consistently brought a clear product and UX vision to discussions, while also remaining highly collaborative and pragmatic in helping the team move forward. The project involved a complex interplay between traditional tooling and emerging AI assistant experiences, and Kevin played an important role in helping bridge those worlds into a cohesive product direction. Engineers regularly sought out his input because he was thoughtful, approachable, and effective at helping identify practical paths through ambiguous product and technical challenges. Kevin was a strong partner to engineering and had a meaningful impact on both the product direction and our technical approach.”
    Yuri Shalfin · Staff Software Engineer, Instacart
  • “Kevin has a rare ability to take complex, ambiguous platform problems — the kind with sprawling user flows and interconnected processes — and distill them into designs that feel simple, intuitive, and inevitable. What sets him apart isn't just his design craft, but his judgment in knowing what to cut and what to keep. Beyond his talent, Kevin is a genuine pleasure to collaborate with: he brings a calm, collaborative energy that makes the hard work of solving difficult problems feel easy.”
    Ann Barzman · Senior Product Manager, Instacart
  • “Kevin is a considerate and thoughtful design partner with a knack for big ideas and blue sky ideation — Kevin constantly looked for intersections between work and rallied designers together to tackle these shared spaces.”
    Pratima Manga · Product Designer, Meta
  • “I was always impressed by Kevin's ability to address different product design asks from various teams, adapt his designs quickly, and communicate clearly to all engineers and XFN on design status. While working together, Kevin had to juggle multiple high impact projects with our team and he did so seamlessly.”
    Justine Koa · Software Engineer, Meta
  • “Absolutely loved working with him! In our work together, I was impressed by Kevin's ability to quickly empathize and balance end user perspectives and organizational objectives and work across XFN stakeholders to drive the UX narrative with leadership and execute with the Engineering.”
    Georgie Mathews · Product Manager, Meta
  • “Kevin is a true leader. We worked on ambiguous projects in which he coordinated standups for engineers, product managers, other designers and teams to get aligned and stay on track of aggressive timelines — Kevin brought a warmth to the team and would be a great culture add to any company.”
    Christy Pham · Content Designer, Meta
  • “Kevin pretty much held multiple teams together by doing a superhuman amount of work. He was leading 10–12 projects at a time from what I could tell and his work was critical to the success of the shopping experience on Facebook and Instagram.”
    Jody Allard · Content Design Manager, Meta
  • “I had the pleasure to work directly with Kevin at Ring — I say pleasure because I never enjoyed so much working side by side with a designer.”
