Work Experience
Hospitality Application to Manage Cafes and Restaurants with Stock, Payment and Accounting Management Project:
Development of microservices for the product that’s being used by hundreds of hospitality businesses daily: cafes, restaurants, etc. Migration of the monolithic application into microservices and deployment using automated CI&CD and tests.
The microservices run on Kubernetes on AWS (EKS) which is load balanced and secured; and is deployed via CircleCI automated workflows from Github repositories via terraform files. The Java services retrieve data from other external partners such as payment gateway providers and feed data into MySQL and Kafka. The frontend has two parts: Groovy Grails (monolith) and React (new product) which communicates with backend microservices via REST APIs secured by OpenID protocol using tokens and Spring Security.
