Matt Bettinson, an infrastructure engineer at Oakbrook Finance, has been instrumental in addressing the company's data management challenges by leveraging MongoDB's capabilities to streamline their loan services for individuals with poor credit histories. Oakbrook, based in Nottingham, specializes in using technology and machine learning to assess credit risk, and has achieved significant growth, ranking 16th in The Sunday Times Hiscox Tech Track 100 list. Facing time constraints and complex data source integration, the team chose MongoDB for its ability to handle diverse data types, enabling them to create precise risk profiles and automate IT operations. This shift to MongoDB Atlas facilitated a transition from monolithic to microservices architecture, improving efficiency and security, especially under GDPR regulations. This technological evolution allowed Oakbrook to focus on customer experience and scalability, with a modern stack including Terraform and RabbitMQ, ultimately helping the company maintain its customer-centric approach.
