3 key aspects related to application design #London

Web (the internet) and mobile apps are elaborated terms. Underneath we have prepared three rudimentary issues, which should be looked-out while planning, estimating and implementing a project.

1. Technologies used to build the application

We advise what kinds of technologies will be the most suitable for the project, depending on application's type, destination and financial plan. Efficiency, functionality, flexibility, scalability and the ability of development are among others the most crucial factors. In order to avoid concerns with application's update or expansion in the future, we suggest using well-known or innovative, but quickly distributed technologies, such as Vue.js, React.js, Laravel, Django, TensorFlow, Keras, PyTorch...

2. Efficiency of web and mobile apps

The final apps' loading time is mostly affected by the efficiency of the application itself and the available IT infrastructure resources (i.e. server computing power). When the app fails itself and creates a heavy load on the infrastructure through many non-optimized processes, we can expand its resources - nonetheless this is just "treatment of symptoms". In the long run, a solution like this can cause damage to your business. The price of maintaining a powerful server unit with heavy traffic will be extremely high. So, it is paramount to So, it correctly design the app's architecture and optimise its code that is responsible for data handling.

3. Methodology of work on applications followed by Software House Sopchy

When we create mobile and web applications, we primarily choose the Scrum / Agile method. When it is used properly it provides the opportunity for quick and flexible accomplishment of a project. Generally, it consists of collecting a list of functions of the web application or mobile application, regulating their priority and joining the work, which is fragmented into so-called "sprints''. Each "sprint" usually lasts from 1 to 4 weeks and brings further functionalities accessible to users. After each sprint, the customer with the team of programmers discuss implemented changes and decide about new goals and their priority.
