I am also currently training the Juniors to become proficient in the IAA
model.
I was tasked with setting up the infrastructure with the company. This
included setting up an Amazon Web Services server to host a Git
repository, Nexus repository, Mantis Bug Tracker and Jenkins build server. I
also used the Google Cloud Platform to host a server that was used to
house the company documentation on a Wiki.
In this project I played a part in the architecture design of the backend
of the application which follows Service-Oriented Architecture. I also
helped design the relational database that the application uses.
I was then tasked with designing the RESTful service layer that is unit
tested with JUnit and inspected by SonarQube. The use of Jasper
Reports was included for document generation within a component of
the service layer.
I was responsible for designing the architecture of the front end
application as well as deciding on the tech stack. It was built with the
Angular Framework and all code is written in Typescript. The application
is unit tested with Karma/Jasmine and end-to-end functionally tested

with Protractor.
The front end is deployed on a Nginx web server which includes a
reverse proxy to the service layer deployed on a Wildfly Application
Server.
