  • Integration with several payment systems. ACI payment integration ( Paypal/Google/Apple pay integration (through ACI gateway). CoDi Payment integration (

  • Developing REST APIs for client apps and other backend services;

  • Developing a Phoenix based admin portal, which allows configuring connected applications, onboarding and managing merchants and partners;

  • Mass onboarding of merchants;

  • Processing and validating massive merchant data from CSV files, using GenServers and finite state machines; Building a resilient data pipeline for bulk data ingestion.

  • Creating and maintaining message queues (with RabbitMQ) for supporting asynchronous communication between various systems;

  • Handling deployment, monitoring and maintenance of these system through kubernetes;

  • Provide technical support and on-call support to all the teams that consume Core services: web, mobile SDKs, client APIs.
