Our client is a UK-based financial services organization operating across multiple regions, handling large volumes of transactional and customer data. With multiple systems supporting finance, risk, and customer operations, the organization relied heavily on data for reporting, forecasting, and strategic decision-making.
The primary objective was to migrate data from a legacy data warehouse environment (Amazon Redshift and on-premise databases) to Snowflake, enabling a unified and scalable data platform. The client aimed to consolidate fragmented financial and customer data, improve query performance for analytical workloads, and enable near-real-time reporting for risk, compliance, and business decision-making.

Migration
Transactional data (trades, payments), customer profiles, and portfolio data were distributed across core banking systems, CRM platforms, and legacy data warehouses, making it difficult to establish a single source of truth.
Complex queries on trade history, portfolio performance, and customer analytics in Redshift resulted in slow performance, especially during peak reporting periods.
Increasing volumes of transaction records, historical data, and market data feeds strained the existing infrastructure, limiting scalability and performance.
Data extraction and transformation processes required manual intervention, leading to inconsistencies in financial reporting and increased operational overhead.
The existing architecture could not support timely updates for dashboards used in risk monitoring and decision-making.
If your data architecture is limiting performance, a cloud data migration to a platform like Snowflake can make a big difference. We help you plan, execute, and optimize your migration for scalable data transformation.
Explore Our Snowflake Consulting ServicesWe executed a structured migration from Amazon Redshift and on-premises databases to Snowflake, focusing on high-volume financial datasets, including transactions, customer records, and portfolio data. This involved extracting data from existing Redshift tables, and loading it into Snowflake with optimized structures. The migration ensured that transactional data models were preserved while being restructured into a format better suited for analytics, with minimal disruption to ongoing business operations.
To support advanced financial analytics and reporting, we redesigned the existing data models into an analytics-optimized structure within Snowflake. Transactional data, such as trades and financial movements were transformed into fact tables. This restructuring enabled efficient querying, improved performance for complex analytical workloads, and better support for use cases such as portfolio analysis, risk reporting, and historical trend evaluation.
We developed automated ETL/ELT pipelines to enable seamless data movement from source systems including CRM platforms and core banking systems into Snowflake via cloud storage. These pipelines handled data ingestion, transformation, and enrichment processes, ensuring that raw data from multiple systems was standardized and integrated into a unified data layer. This automation reduced manual intervention, improved data consistency, and ensured reliable and timely data availability for reporting and analytics.
We optimized Snowflake to handle large volumes of financial data and multiple users accessing it at the same time. This ensured that reporting and analytics could run smoothly without slowing each other down. As a result, queries ran faster and business users were able to access insights quickly, even during peak usage.
To ensure the accuracy and reliability of financial data, we implemented robust data governance and validation mechanisms. This included reconciliation checks between source systems and Snowflake, data quality rules, and monitoring frameworks to detect inconsistencies. These measures ensured that sensitive financial and regulatory data remained accurate, consistent, and trustworthy, providing a strong foundation for compliance reporting and business decision-making.
Query performance on transaction and portfolio datasets improved significantly, enabling faster financial reporting.
Data from CRM, banking systems, and legacy warehouses was consolidated into a single, trusted Snowflake environment.
Business and risk teams gained access to more timely data for decision-making and monitoring.
Automated pipelines eliminated manual intervention, reducing errors and improving efficiency.
