A Streamlined & Efficient Data Transfer Solution for Enhanced FinTech Data Management

Comprehensive Data Migration Solutions for a complex industry


Our fully-digital Banking client aimed to accommodate its rapid growth and gain insights for better member service through revamped data systems. The client came to evolv for assistance in migrating data for their Credit Card, Investment, and Banking products to Snowflake. The data migration project had two objectives: migrate all historical and future data to Snowflake, and recreate reports and queries for legal, operational, and strategic purposes.

The data migration was proven a challenge to scope, particularly in identifying undocumented complexities within the large data warehouse. These complexities ranged from outdated business rules, conflicting logic, unused tables, and more. evolv proactively employed detailed status reports to unveil the hidden complexities and refine the migration strategy accordingly. This iterative process allowed for shifted project priorities as necessary, such as building new and improved reporting dashboards, deprecating unused tables, and fixing known issues in the data. 


To kick off the project, the Data Scientists and Data Engineers compiled a comprehensive list of tables and reports required for migration. This cross-team collaboration was instrumental in ensuring a holistic enterprise perspective and optimizing the overall impact on the business.

As evolv progressed through the list, they encountered numerous unexpected challenges. Following agile principles, the team diligently documented and categorized each issue, classifying them as ‘business critical’, ‘fast follow’, or ‘nice to haves’. All the identified issues were transparently displayed on a dashboard and shared with stakeholders to monitor progress. This practice fostered trust with the client and empowered the entire team to forge ahead.

To ensure continuous progress, evolv held weekly working sessions with stakeholders, addressing their queries and unblocking the development process. They established a dedicated communications channel to seamlessly transition end-users to the new data platform, fostering transparency and connectivity across teams. By leveraging project trackers, daily updates, and transparent communication, evolv successfully delivered on their commitment to efficiently and comprehensively migrating all data and reports.
