A successful mortgage transaction requires the involvement of a number of different entities and their seamless integration. The financial platform must connect in a mortgage broker, a real estate agent, an insurer, a credit reporting agency, and many more. The technology system for such complex financial transactions is built with a layered approach, with the ability to omit or add custom layers or steps into the pipeline for certain operations. Our experts had to modify the top layers, ensuring compatibility with layers beneath. They also performed multiple integrations and added new features to the platform, seamlessly connecting them with the customer’s server-side.

Project description

As already mentioned, the customer’s lending portal is a web application suite that connects brokers, borrowers, and internal users. Leobit‚Äôs experts contributed to the development of each one of them. Our team developed front-end components for three customer‚Äôs websites and built custom CMS with industry-related materials from scratch.

For better understanding, the logic of the successful mortgage transaction process is explained below.

Broker-facing website allows brokers to process online mortgage application before it is addressed to the loan originator. If needed, the website sends documents to the borrowers and notifies them about the brokers’ assignments to proceed further. Borrower-facing website enables borrowers to request a loan, submit documents, select preferable loan programs, fill in the required information (e.g., personal info, employment history, liabilities, assets, etc.), provide eConsent to register the loan, and much more. Utilizing the solution’s interconnected capability, brokers and borrowers can communicate with each other and work together to lower the debt ratio or raise the borrowers’ credit score. The mortgage rate comparison website offers a powerful mortgage calculator for loan comparison and finding the best mortgage type for the borrower’s specific financial situation.

The customer wanted to refresh the user interface of the websites above and make their web apps modern-day. That‚Äôs why Leobit‚Äôs experts migrated them from AngularJS to Angular 8. Migration doesn‚Äôt only improve UI but greatly enhances app maintainability and versatility. Beyond the code rewriting, our team expanded the functionality of the broker-facing website. Leobit developers also created an Angular library for core application functionality reused in both broker-facing and borrower-facing websites. By the customer’s request, our team built a custom CMS used as an educational portal for the brokers and lenders. Internal users publish all the industry-related materials, from the latest mortgage news and updates to webinars and courses. The CMS is built with Angular for the front-end and .NET Core for the back-end side.

Microsoft Azure, used as a web-hosting platform for customer’s proprietary lending solution, guarantees robust security, effective management of the servers, tools, backup, etc., and simplifies app maintenance and scaling.

Our experts broadly expanded the functionality of the customer’s lending platform with multiple integrations. For example, one of the third-party integrations accelerates the loan process, allowing for signing documents online with a legally valid electronic signature. Integration with a pricing engine helps to price mortgage loans with hundreds of lenders in real-time. Another third-party provider optimizes closing processes and services for mortgage lenders delivering timely, accurate, and transparent cost results. An online support ticket system integrated into the platform levels up customer support converting users’ requests into tickets and keeping them well organized.
