Shipped three React 19 clients (player, admin, kiosk-operator) on Vite/Tailwind 4/Zustand/TanStack Query, plus a React Native app (RN 0.79) with biometric auth, QR scanning, and push.
Hardened the platform for regulated real-money play — AML/KYC, MFA (SMS/Email OTP + TOTP), play/deposit/session limits, and six-role RBAC via AWS Cognito.
Integrated Stripe payments/webhooks with the internal wallet, plus Firebase push, SendGrid email, and QR kiosk cash-in.
Provisioned multi-region AWS (eu-west-1/2, us-east-1) with Terraform/Terragrunt; guarded by SonarQube gates and 110+ Playwright/Mailosaur E2E specs.
