About | Design Architect

Hi, I’m Demi - Design architect & product builder

For over a decade I’ve designed B2B and B2C products - from early-stage MVPs to enterprise platforms used by thousands of people.

I work end to end, connecting product strategy, design systems, AI and engineering so products stay coherent as they grow. Today I’m exploring how AI-native products can become more adaptive and easier to understand.

Years of learning
by building

Every stage of my career taught me something different - and each lesson became part of how I design today.

  1. 2015

    Learning craft

    Outsourcing taught me speed, discipline and the fundamentals of visual communication.

  2. 2017

    Learning products

    Product teams taught me ownership, prioritization and user-centered thinking.

  3. 2020

    Learning systems

    B2C products taught me consistency, scalable components and designing for millions of readers.

  4. 2022

    Learning architecture

    Enterprise SaaS taught me complexity, domain thinking and cross-functional impact.

  5. Today

    Learning AI

    AI is changing how products are built, experienced and evolve - and I’m building at that edge.

Contests, workshops, meetups and classrooms - I learn the most when I’m sharing with other designers, organizing, speaking, hosting and coaching.
