About this service

Summary

I specialize in creating scalable design systems that empower teams to deliver consistent, high-quality products more efficiently. My approach goes beyond simply building UI components — I design a cohesive visual and functional framework that adapts seamlessly across web, mobile, and emerging platforms.

Having developed design systems for growing SaaS companies, I understand the unique challenge of balancing flexibility for evolving product needs with consistency to maintain brand integrity. This means creating systems that are:

Robust enough to support rapid feature development

Clear enough for designers and developers to use without guesswork

Flexible enough to accommodate new use cases without breaking existing patterns

I work closely with product, design, and engineering teams to ensure the system is not just a library of components, but a living, evolving asset that streamlines workflows, reduces design and development debt, and scales effortlessly as the company grows.

Process

Discovery & Audit I start by understanding your current design state, brand guidelines, and team needs through stakeholder interviews and UI audit

Foundation Setup Define color palettes, typography scale, spacing system, and core design principles that align with your brand

Component Creation Build reusable UI components in Figma with proper variants, states, and auto-layout for maximum flexibility

Documentation & Guidelines Create comprehensive usage guidelines, do's/don'ts, and implementation specs for designers and developers

Handoff & Training Deliver organized Figma files, documentation, and optional team walkthrough session

FAQs

How long does a design system take to build?
Typically 3-4 weeks depending on complexity. Simple systems (20-30 components) take 3 weeks, while comprehensive systems (50+ components) take 4+ weeks.
What if we already have some design components?
Perfect! I'll audit your existing components, reorganize them for consistency, and fill any gaps. This often speeds up the process.
Do you work with existing brand guidelines?
Absolutely. I'll translate your brand identity into a functional design system while maintaining your visual identity.
What tools do you deliver in?
Primary delivery is in Figma with organized component libraries. I can also provide Sketch files or other formats if needed.
Do you provide developer handoff support?
Yes! I include implementation guidelines, design tokens, and can join developer calls to ensure smooth implementation.
