Data Engineering for AI

Building Clean, Reliable Data Pipelines for Machine Learning and Data Science Systems

Your AI Isn't Broken. Your Data Is.

Why do machine learning models fail even when the algorithms are sophisticated? Why do AI systems produce unreliable predictions, struggle with changing data, or break when deployed in production?

Often, the problem begins long before model training—with the data itself.

Data Engineering for AI is a comprehensive guide to building clean, reliable, scalable data pipelines that support machine learning, data science, and production AI systems. Learn how to transform raw, inconsistent data into trustworthy, well-structured datasets that help AI applications perform more reliably.

Whether you're a data engineer building production pipelines, a data scientist preparing training datasets, or an ML engineer responsible for deploying models, this book provides a structured approach to the data infrastructure behind successful AI.

What You'll Learn

· Build Modern Data Pipelines: Understand data ingestion, batch and streaming processing, ETL and ELT workflows, orchestration, and failure recovery.

· Master Data Quality: Profile datasets, handle missing values, remove duplicates, detect anomalies, validate schemas, and establish measurable quality standards.

· Choose the Right Data Architecture: Explore data warehouses, data lakes, lakehouses, cloud storage, and the trade-offs involved in designing scalable data systems.

· Prepare Data for Machine Learning: Perform exploratory data analysis, engineer useful features, design training and validation datasets, and avoid data leakage.

· Improve Pipeline Reliability: Apply testing, logging, monitoring, alerting, retry strategies, and recovery techniques to keep data flowing correctly.

· Build Reproducible AI Workflows: Learn data versioning, experiment tracking, dataset management, and techniques for making machine learning experiments repeatable.

· Protect Data and Control Costs: Explore security, privacy, access governance, resource optimization, and strategies for scaling data infrastructure.

· Operate AI Systems in Production: Monitor data drift, maintain pipeline health, manage feature stores, and understand emerging approaches such as lakehouse architectures, vector databases, and LLMOps.

Explore the Tools and Technologies Behind Modern Data Systems

Discover concepts and technologies used across contemporary data engineering and machine learning workflows, including Python, SQL, Apache Spark, Apache Kafka, Apache Airflow, dbt, Snowflake, BigQuery, AWS, Azure, Google Cloud, feature stores, and data quality frameworks.

The emphasis is on understanding architectural choices, practical trade-offs, and the principles that remain valuable as tools evolve.

A Practical Roadmap from Raw Data to Production AI

Organized into six progressive parts, this book takes you from the foundations of modern data architecture through pipeline construction, data quality, machine learning preparation, and production operations. An end-to-end pipeline chapter and practical appendices—including a data quality checklist, technical glossary, tool reference, and sample data contracts—help connect concepts to real engineering work.

Who Should Read This Book?

· Data engineers who want to design more dependable data pipelines.

· Data scientists who need cleaner, more representative datasets.

· Machine learning engineers building and maintaining production models.

· Analytics engineers working with transformation and data modeling.

· AI practitioners developing data-intensive applications.

· Engineering managers and technical leaders making data infrastructure decisions.

You do not need to master every tool in the modern data stack to benefit from this book. A working familiarity with data concepts, databases, Python, or SQL will help you get more from.
