Zenith Pathway

Zenith Pathway is a course that helps you move from "writing code" to "building resilient systems" in Ruby. 🏔️
After Quantum Slate, you know how to make code fast and efficient. Now it's time to make it understandable, testable, and ready for team growth and project scaling: domain-driven design basics, clean architecture, design patterns, and principles used in large Ruby projects.

What’s included
9 modules with real architecture examples, code templates, refactoring exercises for entire modules, and structure-building tasks.
Module 1: Clean Code & SOLID in Ruby
Single Responsibility, Open-Closed, Liskov etc. • applying in dynamic language • code smells and removal
Module 2: Domain-Driven Design basics
Ubiquitous Language • Entities, Value Objects, Aggregates • Repository pattern in pure Ruby
Module 3: Clean / Hexagonal Architecture
Layers: domain, application, infrastructure, presentation • dependency inversion in Ruby • folder structure examples
Module 4: Design Patterns in Ruby style
Strategy, Factory, Builder, Decorator, Observer • adapting GoF patterns to Ruby (duck typing + blocks)
Module 5: Test-Driven Development practice
RSpec advanced: matchers, shared examples, stubs/mocks • outside-in TDD • edge case testing
Module 6: Event Sourcing & CQRS basics
Simple event sourcing implementations • command/query separation • why useful for complex domains
Module 7: Refactoring to clean structure
Breaking monolithic classes into services/interactors • using dry-monads or result objects
Module 8: Scalable Ruby without Rails
Microservices-friendly design • message buses (dry-events, simple pub/sub) • background jobs patterns
Module 9: Final project exercise
Building a full domain module (e.g. booking system or inventory) with clean architecture and tests

Who this course is for
Suitable if you:

• already write medium/large projects and feel structural chaos
• want to move from "scripts" to professional architecture
• are ready to invest time in exercises requiring multiple code rewrites for cleanliness 🌟

Not suitable if you:

• are not yet confident with concurrency and profiling
• are looking for quick tricks without deep code reorganization

What you will study
How to apply SOLID and Clean Code principles in Ruby
Domain-Driven Design basics and business domain modeling
How to build hexagonal/clean architecture without frameworks
How to adapt classic design patterns to Ruby
How to write reliable tests and use TDD for architecture
