Cover image for Multi-year technical partnership (2019-present) for

Multi-year technical partnership (2019-present) for a women-only off-road navigation rally across Nevada and California. Work has spanned WordPress, custom plugins, a real-time GPS tracking dashboard (React + Mapbox, 65+ vehicles with satellite failover), scoring system modernization, and live broadcast graphics. Most recent: browser-based live overlay system for OBS/vMix. Built a PHP API layer on top of the existing scoring database without touching the scoring logic, then created JavaScript overlays that production controls in real-time. Standings, challenge results, sponsor graphics, all running as transparent overlays during the 2025 rally. Also built a team bio pipeline (JotForm to WordPress, 130+ profiles/season) and Arduino-based vehicle telemetry hardware for areas with zero cell coverage.

Cover image for Enterprise marketing site migration for

Enterprise marketing site migration for a food safety SaaS company. Two full builds: initial Astro + DatoCMS implementation, then a ground-up Next.js 14 migration with a modular block system so marketing could independently build, preview, and publish landing pages without developer involvement. Built a custom TypeScript component library with GraphQL type safety, reducing new page build time from days to hours. Migrated 246 blog posts and 32 landing pages with zero data loss, maintaining SEO rankings through redirect mapping and metadata preservation. Drove Lighthouse scores from the high 80s to 98-99. Documentation doubled as developer onboarding and AI context, so SafetyChain's own developers could ship features directly from the docs.
