Build Social Media AI Agents: From Practical Implementation to Scalable AI Systems

About the Book

Design-Driven Data Engineering is a practical, end-to-end guide that teaches you how to build modern data systems by starting where it matters most: business design.

Instead of jumping straight into tools, frameworks, and cloud services, this book shows you how to think like a data architect—translating business needs into elegant data models, scalable architectures, clean pipelines, and analytics systems that deliver real value. You will learn a structured, design-first methodology that applies to every platform, whether you work with SQL databases, modern lakehouses, or fully cloud-native solutions.

Through clear explanations, examples, and actionable patterns, you will discover how to:

  • Use design thinking to analyze business processes, events, and data requirements
  • Turn business workflows into conceptual and logical data models
  • Design robust schemas, warehouse/lakehouse layers, and medallion architectures
  • Build ingestion, transformation, and orchestration pipelines that scale
  • Implement governance, metadata, lineage, and quality frameworks
  • Create semantic models for BI and analytics
  • Bring together databases, pipelines, cloud services, and automation into a coherent, maintainable system

Whether you are a data engineer, analytics developer, architect, or technical leader, this book provides a blueprint for designing systems that remain flexible, scalable, and resilient as your business evolves.

Design-Driven Data Engineering gives you the clarity, structure, and patterns you need to build data platforms that don’t just work—but work elegantly.
