WYND
I built two React Native apps that launched within the same six months: a telecom provider’s customer app and an international money transfer app with payments in several currencies.
Illustrations of how these apps worked. Both products have closed or changed since 2021.
The product
WYND builds products for other companies. In 2021 two of them needed mobile apps at once: an internet and TV provider whose customers compare plans and manage subscriptions, and an international transfer service that had to feel safe with real money.
My role
From April to September 2021 I was a front-end engineer on both products, building the React Native apps for Android and iOS with a cross-functional team on tight timelines.
What I did
Built two React Native apps
A telecom service platform and an international money transfer app, both for Android and iOS, both relying on third-party APIs.
Integrated multi-currency payments
Wired payment APIs for several currencies and validated the data flows so cross-border transactions stayed secure.
Shipped real-time notifications
A notification system that kept users informed at every step and drove engagement from launch.
Delivered two launches in six months
Worked with design and backend to ship both products on tight, overlapping timelines.
Craft
Plans, subscriptions and support in one flow.
Amount in, amount out: currencies resolved behind one screen.
Every step of a transfer arrives as a notification.
Impact
Both apps launched on Android and iOS within the same six months, and users stayed well beyond the target.
