What I'm looking for

I'm looking to build high-performance web and mobile products, especially AI-enabled experiences, with strong UI architecture, design systems, accessibility, real-time data, and reliable cloud delivery.

I've built and scaled web and mobile applications at thoughtbot, Wing (Alphabet), Figma, and Amazon. Most recently, I delivered SaaS and AI platform frontends with React, Next.js, Vue, TypeScript, OpenAI, and LangChain, backed by Node and FastAPI orchestration.

At Wing, I built mission-control dashboards visualizing real-time drone telemetry and airspace routes for 250K+ flights, while improving diagnostics and reducing debug time by 25%. I also create reusable design systems, accessible responsive interfaces, real-time visualizations, and reliable AWS-based delivery pipelines.
