Building Apps Without a Proper Backend?

❌

Your app relies on Firebase or Supabase and you're hitting limits

❌

You can't customize your backend logic when BaaS doesn't support it

❌

Scaling costs are unpredictable with third-party backends

❌

You want to add real-time features but your backend can't handle it

Why App Developers Build Their Own Backends in Go

Go lets you build exactly the backend your app needs — fast, reliable, and under your control.

Own your backend

No more BaaS limitations. Build exactly the APIs and logic your app requires.

Fast API responses

Go services respond in milliseconds. Your app feels snappy because the backend keeps up.

Handle real-time features

WebSockets, push notifications, event streaming — Go handles concurrent connections effortlessly.

Predictable costs

Go's efficiency means you know what your servers cost. No surprise bills at scale.

Overwhelmed by all the confusing theory?

You’ve read all the blog posts and tried the theory-heavy books... but you still don’t know where to start.

This course skips the jargon and helps you build something real.

Traditional Content 👎🏻

• Heavy on theory, light on implementation
• DDD, CQRS, Service Mesh... before you even write a handler
• Abstract patterns with no working code
• Weeks before you can build anything.
• More confusing than helpful.

Practical Video Course👍🏻

• Learn by building
• Step-by-step video course
• Real-world microservice system
• 100% practical

Walk away with real skills

Write Go like it's meant for production.
Learn clean structure, useful logs, proper transport, and the kind of organization real teams use.

JWT Auth

Secure endpoints with tokens

Implement login, token generation, and auth middleware.

HTTP + gRPC

Public APIs & inter-service comms

Expose REST to clients and gRPC between internal services.

Event Driven Architecture

Use Nats.IO for async communication

Use publish/subscribe to decouple services cleanly.

DDD-Style Code

Feature-first project structure

Write services that scale and are easy to reason about.

Structured Logging

Understand what’s going on

Use Logrus to log with structure and context.

Dockerized Setup

One command to spin it all up

Run all services with Docker Compose, just like in prod.

I had a technical interview yesterday. They asked about my microservices experience, so I basically walked them through the exact project from the course. Felt amazing.

Build a full Microservice Architecture.
From Scratch

Full project in just 6 steps.

Step 1

⚒️

Service Boilerplate

Learn how to build a service boilerplate. A base that we'll use as a starting point for all our services.

Step 2

🔒

Auth & User Management

Our first service. A service that will handle all our authentication and user management.

Step 3

🎉

Event Service

Learn how to build an event service that can be used to build any event-based microservice.

Step 4

💸

Payment Service

A gRPC first payment processing service. A simple mock of a payment gateway.

Step 5

📝

Booking Service

Let users book event tickers. Covers service interconnections and async communication.

Step 6

🚀

Your First Real System

All the services are done. Let's deploy them with Docker Compose and see the final product.

All that in under 20 hours

You're not learning from a random YouTuber or theory-heavy professor. You're learning from someone who's built real software, led teams, and deployed Go microservices to production.

Hey it's Damian 👋

I'm a former tech lead and self-taught engineer with 10+ years of experience.

I’ve worked at fintech companies like Sygnum Bank, BBVA, and led product teams at startups.

After launching and scaling real backend services in production, I created this course to teach you how to create microservices based apps in a simple way.
