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
Component Library
Built reusable React components with clear documentation, focusing on the most commonly used UI patterns across our platforms.
Style Guide
Comprehensive visual guidelines covering typography, colors, spacing, and brand elements with clear usage examples.
Cross-Platform Standards
Established design patterns that worked across web, mobile, and admin interfaces while respecting platform conventions.
Design System Tools & Assets
Design Evolution: Consistency Across Time
The design system enabled ZeroCater to maintain brand consistency while evolving the product experience. Here's how our website evolved from 2014 to 2020, showing the power of systematic design thinking.

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.

Components in Action: Dashboard Designs
The design system enabled consistent dashboard experiences across customer-facing apps, admin tools, and mobile interfaces. Here's how our components scaled across different use cases.

Customer Dashboard
Clean, data-focused interface using consistent card components, typography, and color system for snacks management.

Admin Interface
Complex data visualization using the same design patterns, showing how components scale from simple to sophisticated interfaces.

Mobile Dashboard
Responsive design system ensuring consistent experience across devices, with mobile-optimized component variations.

Comprehensive Email Design System
Complete email template library with consistent branding, typography, and component usage across transactional, marketing, and notification emails—ensuring cohesive user experience across all digital touchpoints.
Design Process: From Research to Implementation
Building a design system required understanding user journeys, testing multiple design approaches, and iterating based on real usage data. Our process emphasized documentation and validation at every step.

User Flow Documentation
Comprehensive user journey mapping and flow documentation to ensure consistent experiences across all touchpoints and platforms.

Design Iterations & A/B Testing
Multiple design explorations and systematic A/B testing variations to optimize user engagement and conversion rates.
Beyond Digital: Physical Brand Applications
A comprehensive design system extends beyond screens to physical touchpoints. Our design standards guided everything from office signage to delivery packaging, ensuring consistent brand experience across all customer interactions.
