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.

Understanding “red–green–refactor” is easy; applying it effectively in real-world systems is not. This book bridges that gap by showing you how to practice Test Driven Development in the context of building robust, production-ready .NET Core microservices.

Value Stream Mapping for modern software teams. Learn how to measure lead time, expose bottlenecks, eliminate waste, and build a delivery system where value moves efficiently from idea to production.

Design resilient, production-ready microservices architectures with confidence. Learn how API gateways, service meshes, and observability tools work together to build scalable and secure distributed systems.

Discover the complete world of Scala programming in one comprehensive encyclopedia. SCALAPEDIA takes you from language fundamentals to advanced functional programming, covering Cats, Cats Effect, ZIO, design patterns, architectural patterns, and performance optimization. With over 85 chapters spanning 10 major parts, this is the definitive guide for mastering Scala and building enterprise-grade applications. Whether you're starting your Scala journey or looking to deepen your expertise, SCALAPEDIA is your complete reference for modern functional programming in Scala.

Unlock the future of development by mastering high-performance AI backend APIs with ASP.NET Core. Move beyond simple CRUD to architect scalable, resilient, and secure infrastructures for the AI era. Master real-time streaming, gRPC communication, and advanced observability through practical, hands-on examples. Stop just using AI—start building the robust platforms that power the next generation of intelligent software.

You know how to code, but everyone else seems to "just get it" while you secretly Google and ChatGPT everything. The Software Realm DECODED is the patient mentor conversation you've been searching for, Peter asks the questions you're afraid to ask, and the Ultra Senior Developer explains what bootcamps skip and seniors assume you know. By the final chapter, the imposter syndrome disappears and systems finally make sense.

Tired of god factories and 200-parameter constructors? In one intense week, I turned a payment provider monolith into modular, self-registering NestJS heaven. This book shows you how without losing your mind (mostly).

JSON succeeded not because it was better--XML had schemas, namespaces, and 10 years of tooling, but because it understood modularity in ways XML never could. This book deconstructs how a deliberately incomplete format defeated a comprehensive standard, then shows you the production patterns (JSON Schema, JSONB, MessagePack, versioning strategies) that make JSON systems scale from prototype to billions of requests.

Build a real-world digital banking platform from scratch using .NET 10, Clean Architecture, DDD, Angular 21 (Nx Monorepo), Docker, PostgreSQL, and GitHub Actions CI/CD. This hands-on, full-stack guide shows you how fintech systems are built in modern software teams—covering microservices, secure APIs, authentication, event-driven architecture, automated testing, containerization, and more. No shortcuts, no toy examples. Just real engineering.

This second edition isn't about complexity or rare scenarios, rather it's a focused journey for anyone ready to build, learn, and actually ship web applications in Go. I've included the lessons I wish I'd known my first month with Go, plus the methods and habits I still use today. Every step is designed to be actionable, so you can turn any concept into a feature.

Este e‑book foi criado para desenvolvedores que desejam dominar a arte de construir APIs robustas, escaláveis e profissionais usando .NET Core. Se você já trabalha com Visual Studio ou Visual Studio Code e quer elevar suas habilidades para o próximo nível, você está no lugar certo.

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.

Your API deserves more than just working, it deserves to be exceptional.
