Hi, I'm Rachel.
Senior Software Engineer, Developer Experience @ Priceline
A little about me
I am on the Developer Experience platform team at Priceline focusing on web frontend and client architecture strategy. My platform work is grounded in years of leading high-traffic, customer-facing booking flows from search to checkout on product teams.
Platform Strategy
Web monorepo, design system, and a unified client data layer for the whole org
AI-Powered Velocity
Scaling developer speed with modern AI tooling
Product Engineering Focus
Engineering the product details that drive accessibility and conversion
Featured Initiatives
Design System & Brand Strategy
Paired an enterprise-wide design system migration and brand refresh with React 19 readiness, retiring a legacy internal UI framework for a unified, consistent user experience across pages and faster, conversion-driving load times.
Scaling AI Tooling
Built custom Model Context Protocol (MCP) servers and AI agent skills integrated with design and browser tooling. Rolled out across the monorepo, then extended to 8 web apps alongside the monorepo setup. Led 7 workshops guiding 50+ developers through hands-on adoption.
Visual Quality at Scale
Scaled visual regression testing infrastructure (Chromatic) from 8 to 38 projects (4.75x) across the monorepo and external apps, leading 60+ developers to ship 425+ merged design system pull requests through a shared internal configuration package.

Led an enterprise-wide design system migration paired with React 19 adoption, scaled AI/MCP tooling org-wide, and grew automated visual regression coverage 4.75x. Also kept the TypeScript monorepo unblocked through disciplined CI and test ownership, and introduced GitHub Actions and Slack notifications that sped up PR reviews org-wide.
Built new design system components (including a Carousel) adopted by teams across dozens of pages, migrated apps from styled-components to Tailwind, and cut Rental Cars landing-page load time by ~2 seconds.
Led a multi-quarter Rental Cars supplier launch, upgraded apps to React 18, designed the GraphQL migration roadmap, and automated QA deploys.
Shipped Car Upgrade in Checkout at 4.6% conversion, scoped Packages Full Listings at a 90% win probability, and mentored co-op students and junior-to-mid-level engineers across 3+ codebases.
Drove the iOS team's REST-to-GraphQL migration as Web UX point of contact, led Fullstory PII-masking rollout, and improved accessibility across customer-facing pages.
Migrated to streaming SSR for faster TTFB, built 12-factor backing services for the on-prem-to-cloud migration, and fixed a memory leak causing Kubernetes pod restarts.
Introduced Cypress end-to-end testing (later replaced by Mabl), plus the hackathon win above.
Migrated the Rental Cars landing page to TypeScript and advocated WebP delivery via Fastly for faster image loads.
