Web and Mobile App Development for A Sample Fulfillment Platform

Challenge

The client already had a design for the future app, but the technical part of the project was entirely on us. We were tasked with creating a solution that:

• Would work equally well on any desktop or mobile device;
• Could handle large amounts of data because of the constantly increasing number of partners and available samples;
• Would ensure a seamless ordering process using QR codes;
• Could be easily scaled to match growing business needs;
• Was strong enough to handle an unexpectedly high number of simultaneous users — for example, during exhibitions and other public events.

Solutions

The customer for this project is one of our longest-running, most prolific clients who we’ve collaborated with on numerous projects, which is why the choice of tools and technologies for the new project was influenced by our previous collaborations. 

The client wanted to create a unified ecosystem of technologies to further streamline the processes and to effectively work with Microsoft Azure, their existing data management solution. This is why, together, we settled on .NET for the back-end and Angular for the front-end parts of the web solution, which allowed us to create a product with all of the desired functionality, solid scaling potential, and compatibility with a variety of devices.

As for the mobile applications, the choice of technologies there was also dictated by the existing tech stack we’ve successfully used on the previous projects for this client. Swift for iOS and Android SDK for Android applications provided us with the exact level of functionality, flexibility, and scalability we were looking for.

After completing the development part of the project, we set out to verify its integrity and compliance with the original requirements by performing the following types of testing:

• Functional testing
• White-box testing
• Regression testing

As with previous projects for the same client, we employed the Waterfall methodology, which has proven its efficiency time and time again.
