Fleet Billing (lite)

Full-Stack Engineer

Subscriptions and billing for a school-bus operator: operators manage buses and trips and see revenue and seat utilization, while parents pick a plan and pay through Stripe Checkout. A portfolio project with synthetic seed data and Stripe in test mode; source is public on GitHub.

My contribution

  • Built the web app on Next.js 16 App Router: Server Components for stats, tables, and subscriptions, a Server Action for checkout, and client components for the fleet editor and plan picker, in Arabic and English with RTL via next-intl.
  • Built the NestJS API with global auth and role guards, class-validator DTOs, and pure, unit-tested pricing in integer cents (monthly and term plans with sibling discounts).
  • Modeled the data with Prisma on Supabase Postgres and used Row Level Security for parent-scoped subscription reads; roles come from a profiles table, never from user metadata.
  • Integrated Stripe Checkout with a signed webhook that verifies the signature, cross-checks the charged amount, and activates the subscription once per event id.
  • Covered pricing, the webhook, and HTTP e2e with Vitest and web smoke with Playwright; GitHub Actions runs lint, typecheck, tests, migrations, seed, and a Docker build before the Vercel deploys.
