About this service

Summary

I build scalable design systems that make your SaaS development team 3x faster while keeping your product looking consistent and professional. I've architected design systems for fintech products like Nomba Expense, creative platforms like Overlap, and enterprise tools like Station - each serving thousands of users with components that handle real-world complexity. I know exactly what SaaS teams need: components that actually work in production scenarios, not just pretty Storybooks. I focus on creating systems that your developers will love using and your designers will trust, with built-in accessibility, TypeScript support, and documentation that doesn't suck. 🛠️ UI Libraries

Radix UI, Ant Design, Base UI, ShadCN

Process

Discovery & Audit (Week 1) Analyze your current UI patterns, brand guidelines, and team workflow. Identify component priorities and establish design token architecture based on your specific SaaS needs.

Foundation Setup (Week 1-2) Build comprehensive design tokens, configure Shadcn/ui or Radix primitives as the foundation, and establish your custom theme system with seamless Tailwind integration.

Component Development (Weeks 2-5) Create your custom component library built on top of modern primitives, focusing on the components your SaaS actually uses most - from complex forms to data tables to dashboard layouts.

Documentation & Testing (Week 5) Set up comprehensive Storybook documentation with real-world usage examples, accessibility testing, and integration guides that your team will actually reference.

Integration & Team Handoff (Week 6) Integrate the system into your existing codebase, conduct hands-on team training sessions, and provide migration strategies for a smooth transition.

FAQs

Which UI library do you recommend?
I typically use Shadcn/ui with Radix primitives as the foundation - it gives you accessible, unstyled components you can fully customize while maintaining consistency with modern design patterns.
Can you work with our existing design system?
Absolutely! I can audit and enhance your current system, migrate components to modern foundations like Radix, or build entirely new systems that integrate seamlessly with your codebase.
How do you ensure components work in real scenarios?
Every component is built with real SaaS use cases in mind - complex forms, data tables, dashboard layouts. I test them in actual product contexts, not just isolated Storybook examples.
What if our designers want changes later?
The system is built with design tokens, making theme changes effortless. Plus, I provide clear contribution guidelines so your team can extend components without breaking consistency.
Do you provide TypeScript support?
Yes - every component comes with full TypeScript definitions, prop validation, and IntelliSense support to make your developers' lives easier.
