Software Architecture

Turn Python testing from a manual chore into a reliable engineering workflow. Learn pytest through practical examples covering assertions, exceptions, fixtures, parametrization, test organization, coverage, and CI. Build a stronger safety net for your Python projects and refactor with confidence

The Angular companion to NEXUS-1: From File to Framework ports a 5,900-line single-file operator console into a real application, screen by screen, auditing every claim it makes along the way.

Build financial systems that stay correct when requests repeat, events arrive late, and services fail. Learn practical patterns for money modeling, double-entry ledgers, idempotency, reconciliation, auditability, security, and invariant-driven testing—so every balance and transaction can be explained and trusted.

AI has changed the way code is written, but its true impact lies in software engineering. This book explains why specification, architecture, and context have moved to the center of modern development.

Frameworks make it easy to get started, but they often hide the fundamentals. This book takes you back to the core ideas behind reliable software, showing how to build fast, maintainable systems with fewer dependencies and better engineering decisions. Write software you truly understand and control.

Distributed systems can feel overwhelming until you build one yourself. This book takes you from core networking and concurrency concepts to a complete production-ready platform in Go. Every chapter adds real working code so you learn not just the theory but how reliable systems are built and run at scale.

A IA mudou a forma de escrever código, mas o verdadeiro impacto está na engenharia de software. Este livro explica por que especificação, arquitetura e contexto passaram a ocupar o centro do desenvolvimento moderno.

Software teams are building faster than ever, but scaling engineering takes more than great code. This book shows how to create developer platforms that simplify delivery, support cloud-native systems and prepare organizations for the demands of AI. Practical, technical and grounded in real-world experience.

Mexer em uma coisa quebra outra? FOCUS Architecture é uma arquitetura opinativa, organizada por problema, não pela moda, para sistemas que crescem sem apodrecer.

Every online casino is a bank that pays out in seconds, a game studio, and a compliance department wearing the same logo. This is how you build all three, and keep them running. All six volumes in one book.

Big migrations rarely fail because of code alone. The Migration Architect’s Handbook shows how to untangle dependencies, design the right repository strategy and move complex systems forward without bringing the organization to a halt. Built on real-world lessons, it turns daunting modernization efforts into practical, manageable work.

Whether you're deploying your first reverse proxy or managing high traffic production infrastructure, this book gives you the practical knowledge to use NGINX with confidence. Learn not just what each feature does but why it matters, how to avoid common mistakes and how to build fast, secure, reliable systems that scale.

Building an impressive AI agent demo is easy. Running one in production—reliably, at scale, with governance—is where most enterprises get stuck. Agentic Orchestration shows how BPMN-based process orchestration governs AI agents at scale, drawing on real deployments across banking, telecom, and healthcare. Reasoning without orchestration is expensive chaos. This book shows the way out.

Because artificial intelligence generates code in seconds today software engineering matters more than ever. Successful software developers must document system structure, data flow, security boundaries to manage long-term maintainability. Without a clear, thoughtful design framework, AI simply helps teams build a faster, more complex maze of technical debt.

Software is more than code. It is a living system shaped by people, feedback and constant change. This book helps you think beyond features and fixes to understand why systems behave the way they do. Learn practical ideas that lead to better architecture, smarter decisions and software built to last.
