The Challenge: Startup Growth Without Design Chaos

As ZeroCater rapidly expanded from a simple catering service to a comprehensive workplace food platform with mobile apps, web dashboards, and admin tools, we faced the classic startup challenge: maintaining design quality while moving fast and scaling quickly.

Cross-Platform Inconsistency

  • • Web app looked completely different from mobile
  • • Admin tools had their own visual language
  • • Customer-facing vs internal tools felt like different brands
  • • No shared component patterns between platforms

Rapid Growth Pain Points

  • • New features launched with inconsistent styling
  • • No documentation for design decisions
  • • Engineers guessing at spacing and colors
  • • Brand identity diluted across touchpoints

The Turning Point

When a customer complained that our mobile app and website "felt like completely different companies," and our team struggled to maintain brand consistency while shipping features weekly, I proposed building ZeroCater's first comprehensive design system to scale our design quality with our growth.

Building a Startup Design Culture

In a fast-moving startup environment, the design system needed to be practical and adoptable. I focused on creating tools and processes that would actually be used by our small but growing team, emphasizing documentation and clear guidelines over complex tooling.

Practical Design System Approach

Design-to-Development Workflow

Designer-Developer Hybrid Role

When our team lost its dedicated front-end developer, I transitioned from pure design to also taking on front-end engineering responsibilities. Working alongside our Director of Design (who also coded), I contributed directly to the codebase with my own GitHub account, individual pull requests, and full participation in engineering best practices and release cycles.
