2025 - Universitat Politècnica de Barcelona

E-Go

Sustainable Mobility App

Electric mobility app (UPC): stations, range-aware routes, gamification and full backend with Stripe — published APK and deployable API.

Academic context

E-Go is the React Native course project at Universitat Politècnica de Barcelona (2025). I turned course requirements into an ambitious product: not just a map app, but a platform with its own API, real charging data (ICAEN), range logic, subscriptions and an admin panel — plus docs, tests and cloud deployment.

The product

EV and hybrid drivers find active stations, plan routes based on real range, save favorites and compete on leaderboards while charging. The Expo/React Native app consumes an Express + PostgreSQL API with Google OAuth, JWT, Stripe webhooks, geolocation and AWS jobs. Includes an Android APK and architecture ready to scale.

What I built

University project → real product
From coursework to downloadable app, documented API and CI-ready repo.
Maps & open data
Thousands of charging points (ICAEN), filters, favorites and clear mobile UI.
Routes & range (can-reach)
Reach calculation by vehicle and battery to recommend charging stops on real trips.
Gamification & retention
Rankings, live points and rewards (skins, ad-free premium) for engagement.
Backend & payments
Express, PostgreSQL, Stripe + webhooks, Lambda, S3, Docker, Jest/Supertest and GitHub Actions.
Expo mobile app
React Native, Expo Router, TypeScript, Google OAuth and APK on GitHub Releases.
