Qurami is a free app that helps users queue for services at various venues in real-time, providing venue details and ticket status updates. The document discusses a microservice architecture developed in Golang for deploying applications, highlighting features like hot-swappable components and scalable architecture. Additionally, it outlines the development process, including interface definitions and implementation details for the deployer microservice.
