Background
SA Home Loans, a leading player in the South African mortgage lending market needed an upgrade of its data environment to satisfy demand for timely, accurate and actionable insights.
Challenge
With increasing volumes of structured and unstructured data from multiple sources, reporting cycles became longer, data quality inconsistencies crept in, and operational teams lacked the agility to make real-time decisions. To remain competitive, SA Home Loans set out to build a modern data architecture that would enable scalability, streamline reporting, and empower teams with trusted data insights. The organisation required a solution that could not only integrate and cleanse disparate data sources but also future proof its technology landscape against evolving business needs.
Approach
Keyrus designed and implemented a robust cloud-based data architecture that provides a secure, high-performance environment for end-to-end data management. We introduced a flexible architecture that balances governance with speed-to-value and leverages automation and cloud scalability. The deployed technology stack included: · dbt – Enables SQL-based data transformation and modelling with version control and testing. · Apache Airflow - Orchestrates and automates data pipelines, handling extraction, loading, and scheduling with minimal maintenance. · Snowflake – A secure, scalable cloud data warehouse for storage and advanced analytics. · Denodo – A data virtualisation platform that provides unified access and real-time data views for seamless visualization and reporting.
