Frontend in CN Group mainly centre on Javascript

CN Group delivers 40+ different web applications per year and has 80+ Javascript developers ready for your projects.

CN Group is an expert in various types of web applications from heavy content apps to heavy traffic apps, from e-shops to applications for internal networks such as big warehouses, hospitals, etc. Our philosophy is to be technologically flexible and to keep up with the latest trends, including functional programming. We mostly use React, Vue, Angular or elm (purely functional framework). As our usual separator between the frontend and the backend, REST was the number one choice for many years, however we are now using the newer GraphQL which brings significant benefits to our custom solutions.

Expert Backend knowledge

CN Group has strong experience in backend technologies thanks to a community of 90+ developers, the successful delivery of several hundreds of projects, and the use of various technologies.

We mostly develop in Java, .NET, NodeJS, or PHP. We successfully implemented Groovy, Scala, and Clojure. In 2013 we became a Microsoft Gold Partner and for .NET we take all the benefits of the modern .NET Core platform, including functional programming in F#. Microsoft Azure, Amazon Cloud Webservices, or Google Cloud Platform are today playing a more important role in bespoke application development. In PHP we tend to work either with Symfony or Laravel.

Mobile applications

No matter whether you need a Native or Hybrid app, CN Group will help to build any sort of app - from one connected to an IoT device to a native app for your news portal.

Native apps
For Core iOS and Android development, we tend to use SwiftUI as a technology for iOS development and Kotlin for the Android part.

Interpreted apps
Interpreted apps are a step in between a native and a hybrid app solution. Thanks to React Native your team will get many benefits such as sharing code between iOS and Android platforms, between the web and the mobile app, retaining a native-like application.

Hybrid apps
This approach gets furthest from the native feeling and behavior of your mobile app. Typical technologies that represent this approach are Apache Cordova or Progressive Web Apps (PWA) which we love to use for our projects.

Drupal is our favourite Backoffice

We trust most in DRUPAL for building Content Management Systems (CMS). We have experience with both DRUPAL 7 and DRUPAL 8, and can provide either a full Drupal solution or the more popular headless Drupal, which combines Drupal back-office with the technology of your choice, such as React, on the frontend connected through an API.

Our developers are very active in the Drupal open source community and help with arranging and even hosting many events in the Czech and Slovak community.

The User experience and design of your application are what sells the product. Our team can deliver prototypes, wireframes and designs at the beginning of the project. But mainly they can help you with the Design Sprint - a one-week prototyping session where a goal is to create a real-looking prototype from which useful feedback from five end users can be harvested immediately.

At CN Group we live Agile

We started adopting agile techniques back in 2006. Nowadays 99% of our projects are running agile. Our 11 certified scrum masters are at your service.

CN Group primarily uses Scrum enhanced with our own set of best practices. We also use other agile frameworks – pure Scrum, Kanban, LeSS, SAFe, or a completely tailored solution as best suits a particular client or project’s needs.

Our typical team setup is 5-7 developers, testers, scrum master from CN Group  plus a product owner nominated by a customer. Despite working remotely, we acknowledge the importance of face to face communication and one of our key tools for successful projects is regular workshops where we discuss the current topics, business requirements and plan our next slice of work.

Functional programming

The Functional approach means faster development and a lower bug rate, with fewer lines of code in complex applications.

Functional programming as a parallel stream of technologies in backend as well as frontend is mainly used for complex business applications in finance and e-commerce.

CN Group launched its F# team in 2016, delivering many successful projects. On the Java platform we now use Scala. Thanks to elm, we are writing functional code on frontend with no runtime errors. CN Group is a supporter of local Czech functional programming communities such as FSharping and elmPrague.
