Appoint.ly is a time-saving app allowing users to schedule meetings with just one click, providing them with time zone synchronisation and integration with all major calendars. The development of the app included combining several technologies, such as Java Springboot, independent scalable microservices and Docker as a container for those services, MongoDB database, RabbitMQ queues, Amazon SES mailing services and Braintree payments. Frontend components for the web-based application interface were build in Angular.
