At the same time, this technology together with the latest JS frameworks creates a great combination of responsive and multi-functional websites and applications. Beside web-development, our Back-End developers also use PHP for the mobile applications as the server language and development of APIs for external services.

    Today lots of famous platforms and services, like Facebook, Flickr, Wikipedia are based on PHP. Numerous e-Commerce projects and web applications are designed using PHP as well. The reason for that is that the pages of the website are generated quickly because scripts are processed on the server before the browser receives them.

    Python is an object-oriented, high-level programming language with dynamic semantics used to build applications’ back-ends, interact with databases or provide data analysis and visualization capacities.

    Python supports multiple programming paradigms, automatic memory management, and it works great for the creation of both small and big software products. It was designed to have a small core language and one simple way of doing things, but at the same time allows for great extendibility to create complex systems.

    Over the years, Python has verified to be absolutely adaptable to lots of different purposes and has gained popularity among developers. In an exceedingly short period of time, it became a smashing success in the programming world.
