Our Stack:

Rentman is a modern cloud-based web-application relied on daily by our users to administer movement of equipment and access data on the go.

Back-end

• From a back-end perspective, Rentman consists of our internal API, a public API and a set of microservices. The internal API is quite intense on complex database calculations.

• Modern version of PHP and MySQL, used in our internal API

• Modern versions of Laravel, used by some of the microservices

• Our backend is deployed on AWS

• We work based on "Continuous integration" so our systems can be separately run on different versions
   

Front-End:

• Current version of Angular as our main frontend framework, using Typescript

• Compilation and bundling done by Webpack

• Websockets (NodeJS and SocketIO) to sync data between clients

• We work based on "Continuous integration" so our systems can separately run on different version
   

Testing Approach

• Automated unit testing on every pull request

• Automated E2E tests with Ghost Inspector, running weekly and on-demand

• Automated mobile app tests with Appium and Webdriverio

• Weekly manual regression testing

• Manual testing on-demand
   

Methodology:

We follow Scrum with two-week sprints and weekly releases. Our four self-organising dev teams each focus on their own product stream and consist of a product owner and 4 to 6 frontend or backend developers, one of them has the role of scrum master. A dedicated QA team supports testing and manages regression tests and releases. During a weekly 'Tech Alignment' meeting, developers together with the CTO discuss technology, address technical debt and decide on our technical roadmap. 20% sprint capacity can be used for initiatives on the technical roadmap.
