THE CONTEXT

Our Client

Our client-company is a specialist lender offering straightforward long-term loans to Small and Medium-sized Enterprises (SME) in Germany, the Netherlands, Belgium, and Luxemburg.

This bank (our client) works with a network of partners who prepare the loan application on behalf of the SME. The loan approval process starts with an initial screening done using a limited number of questions and critical figures (integrated into a predefined format). Based on the screening results, the bank takes the decision (proceed with the application or not).

Client’s needs/goals

The bank works with a network of partners who prepare the loan application on behalf of the SME. Initially, the process was based on using various apps and platforms – with poor synchronizations between them. This lack of unified systems generated a high risk of errors, data loss, and delays during the process.

So, what our client needed was an online solution that allows easy and secure management for loan applications at multiple levels: Partners (accountants, corporate finance advisors, law firms, tax advisors, private equity funds, and other banks), Borrowers, and Loans Provider (the bank).

The solution

We developed the app by following an Agile software engineering methodology and by using the latest version of ASP.NET and taking advantage of all the modern features from .NET framework.

The app’s architecture is clean, robust, and scalable and integrates several performance optimizations, designed with high-traffic scenarios in mind (index optimizations, partitioning, etc.)

The solution connects 2 apps:

an intranet platform for employees;
an external app for partners and clients.

For hosting, we use IIS on Windows Server, which is one of the best options in terms of reliability, security, and speed. We take advantage of the built-in features like caching and enhanced compression to provide high performance for all the user access levels.
