How we engineer design systems that last.
A repeatable, transparent methodology refined across years of design system work. No black boxes. Every phase produces tangible artifacts your team owns from day one.
Systems, not libraries
A component library is code. A design system is the ecosystem around it — tokens, documentation, governance, contribution workflows, and the organizational alignment to sustain it. We build the full system, not just the parts.
Built for adoption
The best system is the one your team actually uses. Every technical decision we make is filtered through adoption: Will developers reach for this? Is the API intuitive? Is the documentation discoverable? A system that sits unused is worse than no system at all.
Measurable from day one
We define success metrics before writing a single line of code — component reuse factor, token coverage, feature velocity, developer satisfaction. If you can't measure it, you can't prove its value to stakeholders. Every engagement produces quantifiable results.
Discovery & Audit
Understand before you build
Every engagement starts by understanding where you are — not where you think you are. We conduct a rigorous, data-driven audit of your current design landscape to eliminate assumptions and ground every future decision in evidence.
We interview designers, frontend engineers, product managers, and leadership across your organization. We map pain points, workflow bottlenecks, and the informal systems that have emerged in the absence of a formal one. Understanding the human landscape is as important as understanding the code.
We scan your entire codebase — every repository, every micro-frontend, every shared library — and catalog every component. We identify duplicates, near-duplicates, dead code, and inconsistent implementations. The result is a complete map of what exists, what's used, and what's wasting space.
We measure token coverage — what percentage of your styles are driven by a unified token system versus hardcoded values. We catalog every color, spacing value, border radius, shadow, and typography setting across your products. This reveals the true scale of visual drift.
Every component is tested against WCAG 2.1 AA criteria using automated tools (axe-core) and manual keyboard/screen reader testing. We also assess documentation freshness, API consistency, and test coverage. The output is a quantified health score benchmarked against industry standards.
Strategy & Architecture
Blueprint before bricks
With the audit data as our foundation, we design the technical and organizational architecture of your system. Every decision is documented with clear rationale — no "because we've always done it this way."
We define a layered token system — primitive values, semantic aliases, and component-specific overrides. Using Style Dictionary (or Tokens Studio for Figma-first workflows), we create a single source of truth that outputs to CSS, SCSS, JavaScript, iOS, and Android simultaneously. Your designers change a value in Figma; it propagates to all platforms automatically.
We define the hierarchy of your system using atomic design principles — primitives (Button, Input, Icon), composites (SearchBar, Card, DataTable), and patterns (PageHeader, FormLayout, NavigationShell). Each level has clear rules about composition, props, and variant generation. The taxonomy prevents the organic sprawl that kills systems over time.
We design the contribution process — how new components get proposed, reviewed, built, tested, and promoted from alpha to stable. We define ownership, review cadences, versioning strategy (semver), deprecation workflows, and communication channels. The governance model is what keeps a system alive after the initial build is done.
For existing systems, we create a prioritized migration plan ranked by effort versus impact. We identify which components to migrate first (highest usage, highest inconsistency), define backward-compatible shims for gradual adoption, and map team-by-team rollout sequences. Every migration is phased and reversible.
Engineering & Build
Production-grade from the first commit
This is where architecture becomes reality. We build components to the same standard we'd expect in any production codebase — strict typing, comprehensive testing, accessibility compliance, and performance optimization.
Every component ships with strict TypeScript interfaces, comprehensive prop validation, responsive behavior, and variant generation. Tree-shakeable by default. Performance-budgeted per component tier — primitives under 2KB, composites under 8KB.
WCAG 2.1 AA minimum, AAA where practical. Automated axe-core testing in CI (zero tolerance for regressions), manual keyboard navigation audit, and screen reader testing across JAWS, NVDA, and VoiceOver. Focus management patterns for complex interactions.
Chromatic integration capturing every component state across browsers and viewports. Unintended visual changes are caught in PR review — before they reach production. Baseline snapshots for every variant, theme, and responsive breakpoint.
Storybook-powered living documentation with interactive examples, API reference tables, accessibility annotations, and usage guidelines. Documentation is written as the component is built — never as an afterthought. Includes do/don't patterns and composition recipes.
Integration & Migration
Ship without disruption
A system only has value when it's in production. We plan and execute zero-downtime integrations — your users never notice the transition, but your teams feel the improvement immediately.
We never do "big bang" launches. Instead, we migrate team-by-team or product-by-product in 2-week sprints. Each phase is tested independently and can be rolled back without affecting other teams. Backward-compatible shim layers ensure legacy code continues to work during the transition period.
Where possible, we write automated migration scripts (codemods) that transform your existing component usage to the new system's API. This dramatically reduces the manual effort required from your engineering teams and eliminates human error in repetitive refactoring tasks.
We run hands-on workshops for each adopting team covering system architecture, component usage patterns, contribution workflows, and Storybook navigation. We also offer pair-programming sessions during the first sprint of adoption — your engineers learn by building real features with the new system, not from slide decks.
We set up dashboards tracking bundle size impact, render performance, and Lighthouse scores throughout the migration. If a component migration causes a performance regression, we catch it before it ships. Every metric has a budget; every budget has an alert.
Governance & Evolution
Your team takes ownership
A design system is a living product. The governance phase ensures your team can evolve the system independently — adding new components, managing versions, and maintaining quality without our involvement.
A documented, enforced process for proposing, reviewing, and shipping new components. Includes RFC templates, lifecycle stages (Alpha → Beta → Stable → Deprecated), review checklists, and automated PR gates. Engineers know exactly how to contribute without guessing.
Automated dashboards tracking adoption rates, component reuse factor, token coverage, documentation freshness, and developer satisfaction over time. Monthly or quarterly health reports give leadership visibility into the system's return on investment and areas needing attention.
Semantic versioning strategy with automated changelogs, migration guides for breaking changes, and coordinated release schedules aligned with your product roadmap. We set up the tooling (changesets, release-please, or custom scripts) so publishing is a single command.
For teams that want ongoing external expertise, we offer retainer partnerships — dedicated bandwidth for framework upgrades, new component development, contribution review, and quarterly strategic planning. Your external design system team, embedded in your sprint ceremonies.
Your team's tools. Not ours.
No vendor lock-in, no proprietary frameworks. We build on open standards and production-proven technologies that your engineers already know and trust.
