CreditNinja is a fast-growing web loan application and approval service. It requires a loan approval workflow and high-quality solutions and fast code delivery to keep rapid development. 3rd party services needed to be efficiently integrated in order to fetch and store data needed for the decisioning process.

Solution

Integration services were developed using Python3.6 as AWS functions that allowed to use its benefits like concurrency, fast deployments using Chalice framework with versioning, zero-time deployments. The services were called from decision-making service using built-in Python multithreading package which allowed to achieve faster data availability. The code was delivered as CI ready with 95-100% test coverage. Built-in packages usage allowed to keep codebase lightweight for faster deployments and easy maintenance.

Results

Sphere provided integrations allowed CreditNinja to improve the decision model that results in saving money because untrusted customers are filtered out early in the application stages. The whole analytics system became more reliable because of improved test coverage.
