Emily Carter

My name is Emily Carter. I have been working with Ruby for over 8 years, dedicating most of my career to building and reorganizing complex systems — from internal services to high-load production applications. What has always interested me most is not just how to write code, but why Ruby behaves the way it does and how to use its flexibility responsibly.
I started with small automation scripts and gradually moved into large codebases where structure, readability, and maintainability became critical. Over time, I often encountered projects that grew faster than their architecture. The code worked, but it became difficult to extend, test, or scale.
That is when I began studying deeper principles of code organization, modularity, composition, metaprogramming, and architectural patterns in Ruby. I explored how to properly use include, extend, and prepend, how to avoid global side effects from monkey patching, and how to build clean structures without unnecessary complexity.
Over the years, I realized that the biggest challenge for many developers is not the lack of information — it is fragmentation. Ruby offers powerful mechanisms, but without a systematic approach they can easily create chaos. My goal is to help developers see the language as a coherent whole: from its object model to large-scale project architecture.

Professional Background
I have been working with Ruby since 2016. During this time, I have contributed to:
Modular and monolithic systems
Data-processing services (ETL workflows)
Internal automation tools
High-load API services
Gradual legacy code reorganization
My focus is clean architecture, composition over inheritance, clear module structure, and predictable code behavior.
I have worked both in teams of 10+ developers and in smaller technical groups where architectural decisions required long-term thinking and responsibility.

Achievements
8+ years of hands-on Ruby experience
Work on production systems with large codebases
Refactoring monolithic structures into modular solutions
Applying Clean Code and SOLID principles in Ruby projects
Mentoring mid-level developers
I actively analyze new Ruby features, test language updates, and explore modern architectural approaches without excessive framework dependency.

Why I Created These Courses
Over the years, I have seen many developers start with enthusiasm but later struggle with the complexity of growing projects. Many understand the syntax but do not fully grasp the internal logic of the language, its object model, or the consequences of architectural decisions.
I created the Lumiruby courses to systematize my experience and present a structured development path:
from understanding Ruby’s object nature → to working with blocks, modules, and metaprogramming → to building clean architecture and applying production practices.
It is important to me that developers do not simply copy examples but understand what happens under the hood. I believe that deep language understanding leads to more stable, predictable, and maintainable code.
Lumiruby is my way of sharing practical experience without exaggeration or loud promises — just structured materials, real examples, and logical skill progression.
