Today, investment in financial technology and digital transformation is reshaping the financial landscape and generating many opportunities. Too often, however, engineers and professionals in financial institutions lack a practical and comprehensive understanding of the concepts, problems, techniques, and technologies necessary to build a modern, reliable, and scalable financial data infrastructure. This is where financial data engineering is needed. A data engineer developing a data infrastructure for a financial product possesses not only technical data engineering skills but also a solid understanding of financial domain-specific challenges, methodologies, data ecosystems, providers, formats, technological constraints, identifiers, entities, standards, regulatory requirements, and governance. This book offers a comprehensive, practical, domain-driven approach to financial data engineering, featuring real-world use cases, industry practices, and hands-on projects. You'll learn:The data engineering landscape in the financial sectorSpecific problems encountered in financial data engineeringThe structure, players, and particularities of the financial data domainApproaches to designing financial data identification and entity systemsFinancial data governance frameworks, concepts, and best practicesThe financial data engineering lifecycle from ingestion to productionThe varieties and main characteristics of financial data workflowsHow to build financial data pipelines using open source tools and APIs
