Design systems that ship.

Tokens, components, documentation, and the opinionated rules that keep a product consistent across 50+ screens. Below: two production systems I designed and built from scratch.

Case Study 01

Sentinel DS — Built for Security Operations Centers

An enterprise-grade design system for threat detection and incident response interfaces. Purpose-built for SOC analysts working high-stakes, data-dense dashboards where clarity and speed are non-negotiable.

  • 5-level severity scale for alert prioritization
  • Dual themes + 4px spacing grid + motion system
  • 15+ components (alerts, tables, KPI cards, modals, sidebars)
  • Self-contained React drop-in (~1,000 LOC)
  • ARIA roles, keyboard nav, focus indicators — AA out of the box

Case Study 02

Fleet Ops DS — Real-time Logistics at Scale

A design system for a fleet management platform tracking hundreds of vehicles across live telemetry streams. Built to surface anomalies fast without overwhelming dispatchers staring at 20+ feeds at once.

  • Status-driven color system (on-route / idle / attention)
  • 22 components tuned for dense data tables and live maps
  • Monospace typography for telemetry (speed, fuel, DTC codes)
  • Map layer tokens: routes, geofences, heatmaps, vehicles
  • Tested against 500+ concurrent vehicle updates

My Process

From chaos to consistency in 6 weeks.

Every design system I build follows the same pragmatic path — audit the mess, define the rules, ship the components, document the decisions.

01

Audit

Every button, color, and spacing in the current product. I catalogue the inconsistencies so everyone sees the problem.

02

Tokens

Color, type, spacing, elevation, motion. Defined once in CSS variables so design and code stay in sync.

03

Components

Built in React with variants, states, and accessibility baked in. Storybook or live playground for every one.

04

Documentation

Usage, do's and don'ts, code snippets. Good systems fail without good docs — I write them as I build.

What a good design system actually does

Component Libraries

Reusable React components with every state, variant, and a11y requirement solved once — then never again.

Design Tokens

Colors, type, spacing, motion. Defined as CSS variables so a brand update is one file, not 200.

Visual Language

The opinions that make a product feel like itself — documented so new hires don't reinvent them.

40% Faster Builds

New screens in hours, not days. Stop rebuilding the same button for the eighth time.

Designer ↔ Developer Sync

One shared language between Figma and code. Handoffs stop being a source of bugs.

Quality by Default

Accessibility, performance, and consistency become properties of the system — not heroics from each team.
