Problem

Finding available EV chargers nearby is fragmented across multiple apps. There was no simple way to discover, compare, and potentially share private chargers.

What I Built

A React Native mobile app for finding and sharing EV chargers, built as a prototype for Stanford Summer Session's Technological Entrepreneurship course. Includes a Node.js/Express backend with authentication, charger data scraping, and route-based API structure.

Tech Decisions

  • React Native with Expo for cross-platform mobile development
  • Node.js/Express backend with auth middleware and structured route handlers
  • Custom scraping scripts to aggregate charger data from external sources

Outcome

Built a full mobile app with backend API, auth middleware, and charger data scraping.
