The challenge

First of all, it was a completely new sector for the team. It took us a while to learn characteristics of the industry, to familiarize ourselves with fire safety legislations and international standards such as COBie (Construction Operations Building Information Exchange), and to understand our client’s needs. Secondly, we had to take into consideration four different levels of user access depending on the role they have in a particular company. Eventually, redesigning the entire platform is always a big responsibility to clients and users - and we were ready to accept this challenge!

The solution

To build a good user experience, we have become experts in this field, expanded the functionality of our software, and presented convenient and reliable solutions in the mobile app and BackOffice for all user access levels mentioned above. Moreover, we have created a design system from scratch (including new icons, typography, components, and illustrations).

Main features

The data provided by our client demonstrated that users wanted to have an ability to customise some of the features. The limited functionality of the applications could not cover these needs fully. 

Thanks to our improvements, companies can now add the opening hours of each of their facilities, configure intervals and frequency of fire safety inspections, and assign responsibilities to employees.

Additionally, we have unified the data of the online, PDF & Excel reports, decreased the time for report generation process and made the reports more readable and easy to understand.  

On the part of the mobile application we have started to notify users about the availability of a new update and allowed them to use the TFS Compliance app in offline mode.

# **Web app** development

Our developers specialise in creating various web services, starting with simple scripts and ending with **advanced web applications.**

Web app development

Backend and API are the two technologies that make up the backbone of any platform or application. Backend functions as the main storage for all the processes and information needed to run the software. API - Automatic Programming Interface - allows interaction between a software and the backend's functionality. Even such a simple process as user authentication is only possible due to the interaction and data exchange between the API and the backend.

The backend and frontend are the two underlying parts of any software. The frontend is a shiny component, or everything the user sees and does in the app. The backend is hidden - it powers the whole solution by connecting servers, APIs, and data for processing all user requests and actions. A functional backend is vitally important for any digital product as it lays the foundations and structures the future software. In the opposite case, if the backend is not done properly, it can ruin the whole application by limiting its functionality, design, and even preventing scalability. 

A Dev and Deliver expert team uses an advanced tech stack for building top-notch scalable software solutions. Our main programming languages for the backend are Node.js and Kotlin. They are comparatively new but already received an excellent reputation because applications written in these languages show high efficiency, fast speed, and flawless performance. When it comes to backend frameworks, our developers in Poland choose Laravel and Symphony to automate processes and deliver applications much quicker. 

Why backend is important?

How to choose the right technology?

cloud or on-premise deployment / integration with the client-end

discovery / conceptualization / choosing software type / scope of the project determination

database development / database and APIs setup
