Do Any Of These Feel Familiar?

Have you ever felt stuck in your career as software developer?

You are not leveling up your skills, and your job is not helping you grow.

Do you want to become a software architect but don't know how?

The traditional way to becoming an architect is long and filled with costly mistakes.

Do you struggle to make system design decisions?

Traditional resources are often disconnected from real world applications.

You are overwhelmed by the resources online.

The best way to learn is from specific examples.

If you answered “no” to all of the questions above, awesome! You don't need this.

Hexagonal Architecture Pattern

To become a Software Architect, you need a solid architectural pattern to structure your code. Hexagonal Architecture is the right place to start. This document explores how the Hexagonal Architecture pattern helps teams build systems that can absorb changes gracefully, supported by a practical example: executing a money transfer in an online banking system.

Complete Case Study — Flight Search System

Modern flight booking systems must integrate with multiple airline providers to offer search results. Each provider respond at different speeds and may fail independently. The challenge is building a system that can dispatch requests to all providers simultaneously, collect responses as they arrive, and present progressive results to users in real-time. This document solves this aggregation problem effectively.

System Design Patterns

System design heavily relies on established design patterns. You can design distributed systems by using a combination of these patterns. These patterns are crucial for building reliable, secure, operationally efficient architectures that are optimized for cost and performance.

Digital Bank Architecture

Good architects design their diagrams based on the target audience. Business people never enjoy your technical diagrams. Developers admires who explain the why behind decisions. This course navigates a real digital banking solution. Starting with the use cases analysis diagram all the way to components diagrams, explaining the why behind each design and architecture decision.

Clean Architecture Pattern Hands-On

This course aims to create loosely coupled components that can be tested independently with no dependencies on data stores, message brokers or UIs. This pattern helps prevent technology lock-in. It covers folder setup, core domain logic (anemic vs. rich), use case orchestration, and plugin gateways implementing core interfaces.

Web Applications Scalability

This course includes lessons on the 5 components of highly scalable web applications. From caching and queueing to minimizing storage locks, handling asynchrony, and building redundancy, Scalability is the thing that separates good web applications from excellent ones. If you’re serious about building apps that don’t crumble under load, this is for you.

Architect Bundle

This bundle is for engineers who already understand the basics and want to make better architectural decisions. It includes everything in the Core Architecture Bundle, then goes further. You’ll see how real systems are designed, evolved, and defended under constraints like scale, reliability, cost, and change. If you want to explain your designs with confidence, and think like an architect, this is the bundle.

Core Architecture Bundle

This bundle covers the fundamentals you need. You’ll learn how to structure business logic cleanly, understand how real systems are put together, and design web applications that scale beyond a single server. If you want solid foundations, start here.
