Learn how to keep database code outside your business rules while using Go ports, MySQL repositories, transactions, connection pools, ORM boundaries, and controlled schema migrations.
Learn how to design a REST API before implementation, generate Go server contracts from OpenAPI, keep HTTP code outside the domain, and evolve public endpoints without breaking clients.
Learn how to structure a Go service around models, ports, services, and adapters so business rules stay testable while databases, transports, and messaging tools remain replaceable.
Learn how to run a Go HTTP server with external configuration, safe timeouts, clear routes, observability headers, and graceful shutdown for reliable production deployments.
Learn how to design concurrent Go services with clear goroutine lifecycles, safe channel ownership, bounded fan-out, cancellation, error handling, testing, and production monitoring.
Learn how Go decides whether values live on the stack or heap, how pointer choices affect performance, and how to verify allocation behavior with compiler output and pprof.
Learn how to use Go's built-in testing tools to write clear unit tests, table-driven tests, subtests, parallel tests, benchmarks, fuzz tests, and CI-friendly checks that reduce production risk.
Learn how to turn Go's functions, structs, methods, interfaces, control flow, loops, and error values into clear service behavior that is easy to test and maintain.
Learn how to use Go's primitive types, variables, constants, pointers, operators, slices, maps, and conversions to write clearer and more memory-aware production code.
Learn how to evaluate Go against Java for enterprise services across interfaces, builds, deployment, concurrency, testing, memory behavior, dependencies, and team readability.
