Full-stack web engineer. 8+ years shipping product experiences in React, TypeScript, Next.js, and GraphQL — for 100M+ customers at Intuit, Walmart, and Rivian.
Currently a Staff Software Engineer at Intuit, on the design system behind QuickBooks, TurboTax, Credit Karma, and Mailchimp. Before that: identity and account experiences at Intuit, founding engineer on Rivian's Fleet Core, and marketplace + core components at Walmart.
Product & web UI — React, Next.js, and TypeScript apps end to end: seller and account flows across homepage, search, item page, cart, and checkout. Performance is part of the job — 56% P95 cuts via bundle splitting and render work, 15% page-speed gains on the Walmart PDP.
Design systems & UX engineering — 100+ shared components with theming, accessibility, and Storybook as the sign-off surface for design and PM partners. Twice, at two Fortune 500s.
Full-stack — GraphQL schemas and REST-to-GraphQL migrations, Node and Spring Boot services, event-driven systems on SQS/EventBridge/WebSockets, and AWS (Lambda, S3, CloudFront, SES).
AI-native interfaces — LLM and MCP-based prototypes, agentic workflows against production APIs, and running the frontend org's AI-assisted engineering practice.
