Web applications

Large-scale and complex custom web applications that work across all popular browsers, are fast, reliable, and deliver immaculate UX with intuitive navigation and logical workflows.

Our expertise covers a wide range of enterprise applications for core business aspects from sales and customer service to manufacturing and inventory, human resources, finance and marketing management:

Mobile applications

Native (iOS, Android, Windows) and cross-platform (on Cordova, Xamarin, React Native) mobile applications to provide businesses with speed and convenience they need.

Qrapp can either compliment your web application with mobile experience or deliver it as a separate mobile solution with its own back end (.NET, Java, PHP, Node.js).

Desktop applications

OS-specific (Windows, Mac, Linux) or cross-platform custom applications to work offline with total control over data security.

Big data applications

Leverage the power of large data sets with high-performing and robust custom big data tools.

Our big data solutions empower manufacturing, banking, healthcare, media & entertainment, logistics, sports industries and the government sector with clear insights on critical elements of their business and let them explore patterns and trends for more informed actions, better process control and optimization, predictive equipment maintenance, ad/service/content targeting, and more.

Qrapp provides solutions that can analyze:

Real-time applications

A wide range of real-time tools for immediate identification of potential business opportunities and risks.

Qrapp’s team develops such solutions as sensor data monitoring (equipment condition monitoring, environmental monitoring, automatic vehicle tracking), advertisement and recommendation engines, fraud and spam detection, highly-responsive applications with millions of users and more.

Technology consulting

We help you with professional advice on the right technology stack and architecture for your future app, gather security requirements and offer measures to fulfill them, provide a scalability roadmap.

Development from scratch

Qrapp provides end-to-end development services. We either create a detailed requirements specification at the initial stage of SDLC (in case of a traditional linear approach) or continuously adapt to changing project requirements during Agile iterations.

Step 1 – Discovery
We take time to thoroughly understand your business and align the future solution with its objectives, gather security, functional and operational requirements. Then we proceed with describing workflows and user scenarios.

Step 2 – Design and prototyping
We decide on the most beneficial architecture, from traditional, service-oriented architecture (SOA) to microservices, cloud-ready, and reactive architectures, and proceed with the high-level application design.

Step 3 – Development
We assign a designated development team to build the future app according to the requirements set.

Step 4 – Testing
Our testing team runs the app through a comprehensive testing process to verify its quality and compliance with all requirements. Wherever possible, we apply to high level of test automation for improved coverage and speed.

Step 5 – Deployment / Launch
Our release engineers integrate the new app into the existing IT environment.

Step 6 – Support
We proceed with thorough post-release support, managing incidents, configuration changes and updates to ensure a smooth handover, stable availability and relevance of the new application.

Development based on a requirements specification

You share your precise documented description of the future application and we proceed with the rest to turn your vision into a real working solution.

Traditional architecture – providing a 3-tier (front end – back end – database) construction for quick development and easy maintenance.

Microservices architecture – splitting an application into several independent units based on business functions. It allows for the use of a mix of technologies and languages, continuous deployment, increased performance, partial updates, and appropriate management of increased loads.

Reactive architecture – designing reliable and flexible systems and applications that ensure high responsiveness and availability in the context of multi-userness, streaming data and high load.

Cloud-native architecture – developing an application for the cloud that can leverage cloud-related benefits (simplified portability, automated performance scaling, PaaS services) to the fullest.
