Build bulletproof Spring Boot microservices—from monolith migration to domain-driven design and event-driven patterns—while mastering the production essentials of resilience, observability, and zero‑downtime delivery. Turn complex domains into clean, scalable services with bounded contexts, aggregates, repositories, and domain events, then ship faster with rate‑limited APIs, backoff‑retries, and Kubernetes rollouts. If leading Java teams to reliable, cloud‑ready microservices is the goal, this is the hands‑on guide that gets systems into production with confidence.

One of the most comprehensive no-fluff guides for software developers to help them write clean code every day. The book is packed with principles and patterns that help developers, from novices and juniors to seniors and experts, to write cleaner code.

Cloud computing and network administration have gone a long way, and I am both excited and amazed by this fact as I sit down to write this book. This book is my attempt to explain the world of service meshes with a deep dive into Linkerd in the possible smallest book size, and is the result of countless hours spent in demystifying complex systems.

Which HTTP method should I pick for my API path? Look it up in the RESTful dictionary.

Become a Job-Ready API Automation Engineer Using PlaywrightAPI testing is now a must-have skill for modern QA engineers.

A practical backend interview reference covering modern Java and Spring Boot development.

We'll build an agent step-by-step, starting with a small loop that accepts input and produces structured output. As we go, we'll add tools, validation, model switching, runtime adapters, and packaging techniques that'll let the agent move from a simple script to a reusable application.

A step-by-step Playwright + TypeScript guide for manual testers or who wants to switch to becoming automation engineers.
