funcRoadmap()[]Stage

A structured path through Go and backend engineering, in the order most people actually need it. Stages with a published guide link straight to it; the rest are on the way.

1. STAGE 01

   Go Fundamentals

   Syntax, types, and the standard library patterns everything else builds on.

   • Go Interfaces: Design Small, Testable Components
   • Error Handling and Custom Error TypesPlanned
   • Structs, Methods, and CompositionPlanned

2. STAGE 02

   Concurrency & Asynchronous Go

   Goroutines, channels, worker pools, and patterns for coordinating concurrent work safely.

   • Context in Go: Cancellation, Deadlines and Request Propagation
   • Advanced Go Concurrency: Worker Pools, Backpressure and Bounded Concurrency
   • Building Background Workers in Go with Goroutines and Channels
   • sync.WaitGroup, sync.Mutex, and the Race DetectorPlanned

3. STAGE 03

   Building & Securing Backend APIs

   HTTP servers, REST architecture, clean patterns, security, rate limiting, and caching.

   • Building a Production-Ready REST API with Go
   • Building a Go API with Clean Architecture Without Overengineering
   • Graceful Shutdown in Go HTTP Servers
   • Securing Go REST APIs: Authentication, Authorization and Attack Surfaces
   • API Rate Limiting in Go: Token Bucket, Middleware and Distributed Limits
   • Caching in Go: Redis, Cache-Aside and Cache Invalidation
   • Idempotency in APIs: Preventing Duplicate Payments and Requests
   • Designing a Production-Ready Go Backend: Architecture, Reliability and Operations

4. STAGE 04

   Working with PostgreSQL

   Indexing, query analysis, transactions, connection pooling, and database scaling.

   • PostgreSQL Indexes: A Practical Guide for Backend Engineers
   • EXPLAIN ANALYZE in PostgreSQL: How to Find Slow Queries
   • PostgreSQL Connection Pooling in Go: pgxpool Explained
   • Database Transactions in Go: Isolation Levels, Locks and Real-World Failures
   • Scaling PostgreSQL for Go Applications: Read Replicas, Connection Pools and Query Performance
   • Database Migrations and Schema VersioningPlanned

5. STAGE 05

   Testing

   Unit, integration, and HTTP tests that catch real regressions in Go applications.

   • Testing Go Backend Applications: Unit, Integration and HTTP Tests
   • Fuzzing and Property-Based TestingPlanned

6. STAGE 06

   Microservices & Resilient Architecture

   Project structure, communication protocols, fault tolerance, retries, and event-driven patterns.

   • Go Microservices: A Practical Project Structure
   • REST vs gRPC for Go Microservices
   • Circuit Breakers in Go: Preventing Cascading Failures
   • Retries, Timeouts and Backoff in Go: Building Resilient Services
   • Event-Driven Architecture with Go: Events, Consumers and Failure Handling
   • The Outbox Pattern with Go and PostgreSQL

7. STAGE 07

   Distributed Systems Patterns

   Distributed locking, idempotent message consumers, and multi-node concurrency.

   • Idempotent Consumers in Go: Handling Duplicate Messages Safely
   • Distributed Locks in Go: Redis, PostgreSQL and the Problems You Need to Understand

8. STAGE 08

   Performance & Load Testing

   Profiling, load testing, benchmarking, and resolving performance bottlenecks under load.

   • Profiling Go Applications with pprof
   • Load Testing a Go API: Finding the Real Bottleneck
   • Writing Effective Go BenchmarksPlanned

9. STAGE 09

   Cloud, Deployment & Observability

   Kubernetes, microservices observability (logs, metrics, traces), packaging, and operating Go in production.

   • Kubernetes for Go Developers: Deploying a Production-Ready Go API
   • Observability for Go Microservices: Logs, Metrics and Traces
   • Dockerizing Go ApplicationsPlanned
   • CI/CD Pipelines for Go ServicesPlanned
