Protect-A-Plate

RemoteDev Limited · Feb 2026 – Present

UK vehicle anti-cloning platform on web (Next.js 16), iOS, and Android (React Native), serving six user roles — driver, plate supplier, fleet operator, insurer, and internal admin — from one Node.js backend across 134 API routes. Billing runs through Stripe, Apple In-App Purchase, and Google Play Billing, reconciled into a single account-level entitlement resolver.

  • Unified Stripe, Apple IAP and Google Play Billing behind one entitlement resolver
  • Moved billing from per-plate to four account tiers, collapsing the state space
  • AES-256-GCM VIN encryption with HMAC-SHA256 blind indexing for duplicate detection
  • Diagnosed duplicate IAP transactions and token-refresh loops in production
