Staff Product Designer — design systems · AI-native workflow
Led UX for a $3.8B subscription platform at Deere across web, mobile, and embedded equipment systems (500K users, 12 languages). Built design org 1→10 at FourKites scaling a real-time IoT asset-tracking platform processing 10M+ daily events ($3M→$100M ARR, $1B+ valuation). Now founder of Thios (thios.co) — running an AI-native workflow (Claude, Cursor, Figma Make) to ship a CAD-driven configurator, dev-grade design system with its own Claude Skill, and physical hardware.

Thios thios.co
Aug 2024 – PresentFounder & Lead Designer
Open-source modular structures running on a 5-surface design system where I'm the only designer and agents are the engineering team, every surface (DESIGN.md ↔ tokens.json ↔ main.css ↔ design-system.html ↔ OnShape) ships from one source of truth.
- Shipped a complete product ecosystem solo in 21 months — 6 sphere variants with CAD models, prototype, first revenue across every surface.
- Designed and built parametric OnShape CAD as the single source of truth driving BOM and the 3D configurator at thios.co/configurator — customers manipulate real geometry with full configuration state (valid/invalid combinations, loading, error, empty, BOM hand-off), not marketing renders
- Built a 5-surface, dev-grade design system, published its first Claude Skill (
audit-design-token-drift) that catches design-token drift across canonical surfaces with file:line citations. Design system as dev tooling, not a Figma library nobody opens — thios.co/design-system-architecture
John Deere
Aug 2020 – Jul 2024Senior Lead UX; Digital Customer Experience
Embedded with product teams to modernize 20-year-old systems and drive subscription revenue across connected agricultural equipment. Proving enterprise design can move fast with the right frameworks.
- Redesigned the license management system for connected ag equipment (Automation/AI services) serving 500K+ users across 12 languages — mapped flows, license states, and edge cases (expired/renewed/transferred/dealer-managed); +34% monthly active authenticated users, –16% support tickets, enabled $3.8B in subscription revenue
- Built a unified account and navigation framework deployed across 8 product lines spanning web, mobile, and embedded equipment systems — consolidated fragmented experiences into a single customer view; +28% first-contact resolution on dealer support
- Core contributor to the enterprise design system in Figma spanning 6 brands and 40+ product teams globally — produced dev-ready handoffs (tokens, prop specs, full state coverage) that reduced design-to-development time 45% on components that actually shipped

- Led predictive analytics dashboards (data viz, anomaly states, alerting workflows) that identified shipment delays 6–12 hours earlier than competitors; +41% retention, +$120K avg ACV
- Scaled the design org across Chicago and Chennai embedded in engineering sprint cadence; established component library, design ops, and hiring framework — –65% one-off component variants while maintaining startup velocity
