One of the latest full-scale project of our company was test system development. Otest online test generator software was created for content services website of our customer. The system built based on the mix of technologies such as Angular 2, RxJS, Bootstrap, NodeJs, ActionHero.js, mongoose and MongoDB, allows to create tests of different types and check the knowledge and skills of potential vendors. Otest generator has a rather complicated inner structure, but the right choice of working solutions and technologies helped cut the cost of the whole development. Subtle and intuitive design lets the users easily find the necessary tests without any distraction. Contact us to get web systems and widgets of use!
