Notable Projects

Frontend Monorepo Architecture & Infrastructure

Architected a flexible, scalable frontend monorepo using Turborepo and pnpm to accelerate iteration and enforce visual consistency across multiple product lines. Unified different tools and frameworks like Astro, Next.js, and Vite under a shared structure to support cross-domain development and component reuse. Led development of a CI-integrated Playwright test suite that ran against our staging environment to validate critical user flows before production releases. This served as a robust safety net, surfaced regressions early, and allowed the team to move quickly without sacrificing reliability or UX.

Interactive Personalized Diagnostics Platform & Custom Rules Engine

Led the transformation of Ro's diagnostics experience from static PDFs to a dynamic, browser-first health dashboard with interactive charts and personalized next steps. Built a custom rules engine atop a forked json-rules-engine package, enabling healthcare professionals to define thousands of result permutations as rules defined in a headless CMS. The system handled 25+ biomarkers and incorporated enhanced RBAC to protect HIPAA-sensitive data. The new experience significantly improved patient comprehension and was embraced by medical teams as a breakthrough tool for proactive care.
