Fiserv is a global fintech and banking solution provider that handles over 1.5 trillion US dollars in processing, with Jay Duraisamy leading its newly established data and analytics division. The company aims to gather data from various business units, align it, and unlock its value to provide new services for merchant customers and consumers. Customer expectations are changing, with a focus on differentiated services and real-time access to data, which Fiserv is addressing by building a data platform that brings together data and analytics on one platform. This platform will enable the company to create a 360-degree view of customers and merchants, providing value through unique and shared services. Fiserv's data platform design considers connecting data from different business units, serving both batch and online modes, and maintaining historical data for batch processing. The team is building a hybrid architecture that combines on-prem and cloud-based tools, such as ETL tools, Kafka, Snowflake, and YugabyteDB, to provide real-time data access and scalability. Jay believes in a platform- and product-centric approach to measuring business value, identifying customer problems that traditional architecture cannot solve, and choosing the right architecture depending on the context and customer needs.
