@christophertourmenti

I build modern payment, gift-card and loyalty platforms with TypeScript, React, Next.js and Laravel.

At Yoyo International (wiGroup), I've modernised merchant and consumer portals for digital gift cards, vouchers, loyalty and payments, re-platforming legacy PHP, CodeIgniter, Laravel and Vue applications into Next.js, React and TypeScript.

I've built the wiPlatform merchant portal, the Yoyo Gifts consumer gift-card storefront, and the wiCode self-service admin portal with AWS Amplify and embedded Amazon QuickSight analytics. I also deliver authentication, REST and SOAP integrations, cloud deployments, and a standardised frontend toolchain using TanStack Query, Zod, Tailwind, Orval, Vitest and Playwright.
