Go Backend Development: HTTP APIs, Concurrency, and Databases

To build high-performance web applications, you need to understand how your programming language manages memory and handles concurrent tasks. Go is designed for exactly this, offering unparalleled efficiency for backend services. This text-based course guides you from the foundational concepts of Go's runtime to building a production-ready HTTP API. You will gain a deep understanding of how Go works under the hood and how to write clean, concurrent, and database-driven backend applications. What you'll learn: - Understand Go's internal memory model, including the stack, heap, garbage collection, and memory allocation. - Master concurrency using goroutines, channels, and synchronization primitives to write non-blocking code. - Build a robust HTTP API from scratch using the standard library's native routing and request handling. - Integrate PostgreSQL databases using the GORM ORM and manage your database environment with Docker. - Implement modern structured logging and clean error-handling patterns to ensure your application is production-ready. - Practice writing clean CRUD operations and managing application state safely. You will start by exploring foundational Go terminology, memory mechanics, and concurrency basics. Then, you will progress to hands-on backend development, building a complete HTTP API step-by-step, connecting it to a database, and structuring your code for real-world use. This course is designed for developers who are new to Go backend development or want to solidify their understanding of Go's internals and web patterns. No advanced Go experience is required to begin. Read the lessons, analyze the code examples, and start building high-performance Go backends today.
