  • PaymentsCard payment gateway handled across iOS and Android
  • MultilingualFull app overhaul with localization for new markets
  • ArchitectureMVVM, MVP, Hilt/Dagger, RxJava, Coroutines
  • Release engineeringGradle build optimizations and dependency management

Backend & platform

The services, data, and infrastructure those clients run on.

  • REST APIsDesigning and building the services the apps talk to
  • Data modellingPostgres database schema design
  • AuthenticationFirebase Authentication and Firebase NoSQL data
  • DeliveryDocker containers behind Nginx reverse proxies
