In Refactoring at Scale, software architect and engineering leader Maarten Smeets reveals how high-performing teams transform fragile, aging systems into scalable platforms-without breaking production or slowing down delivery.
Drawing on real-world lessons from large engineering organizations, this book presents a practical framework for safely evolving complex systems while your business continues to run.
You'll learn how to:
Turn risky big rewrites into safe, incremental refactoring strategies
Identify high-leverage improvements hidden inside legacy systems
Use testing, observability, and architecture patterns to reduce change risk
Align engineering teams around continuous modernization
Scale refactoring efforts across large codebases and multiple teams
Replace technical debt with technical leverage
Packed with battle-tested techniques, architectural patterns, and organizational strategies, Refactoring at Scale shows how the best engineering teams modernize their systems without stopping the world.
Whether you're a staff engineer, architect, or engineering leader responsible for long-lived systems, this book will help you turn legacy code from a constraint into a competitive advantage.
