Projects
A selection of projects I’ve built and shipped to production.
Lumen AI Support Assistant
An LLM-powered support assistant embedded in a SaaS product, resolving 40% of tickets without human intervention.
**Problem:** Support volume was outpacing the size of the customer success team. **Solution:** Built a retrieval-augmented chat assistant grounded in product docs and past tickets, with a human handoff for low-confidence answers. **Results:** Deflected 40% of incoming tickets in the first month and improved median response time from 6 hours to under 1 minute.
Northwind Analytics Dashboard
A real-time analytics dashboard with sub-second query performance, built for a logistics company managing 10,000+ daily shipments.
**Problem:** Northwind's ops team relied on manual spreadsheet exports to track shipment performance, causing multi-hour reporting delays. **Solution:** Designed a real-time dashboard backed by a materialized-view PostgreSQL schema and WebSocket updates, cutting reporting latency from hours to seconds. **Results:** Adopted company-wide within two weeks of launch; cut manual reporting time by 90%.
Signal — Design System
An open-source, accessible React component library and design system used across six production products.
**Problem:** Multiple product teams were each building their own inconsistent UI components, slowing delivery. **Solution:** Authored a themeable, WCAG 2.2-compliant component library with full test coverage and Storybook documentation. **Results:** Cut new-feature UI development time by roughly 30% across adopting teams; 2,000+ GitHub stars.
Fieldnote Mobile Companion
A React Native field-service app that lets technicians manage jobs, capture signatures, and sync offline.
**Problem:** Field technicians frequently worked in low-connectivity areas, causing lost job updates and duplicate data entry. **Challenges:** Building a reliable offline-first sync engine that gracefully resolved conflicting edits across devices. **Results:** Reduced data-entry errors by 45% and became the primary tool for a 300-person field team within one quarter.
