About Lumiruby

Lumiruby was created in response to a common issue: many Ruby materials provide only a surface-level overview of syntax without explaining how and why the language behaves the way it does. The founder of the platform has spent years working with Ruby in different contexts — from small scripts to complex production systems — and repeatedly observed that even experienced developers often lack a deep understanding of the language foundation.
While working on real-world projects, it became clear that issues in architecture, performance, or maintainability often start with gaps in understanding core mechanisms. Why is everything an object? How does dynamic typing work in practice? When is metaprogramming appropriate, and when should it be avoided? Many of these answers had to be discovered through documentation analysis, source code reading, and experimentation.
This led to the creation of Lumiruby — a platform with structured courses that explain Ruby step by step: from fundamental concepts to large-scale code organization, optimization, and production practices. Our goal is to help developers not only write code, but understand its behavior, see the consequences of architectural decisions, and work confidently with the language at different levels of complexity.
Lumiruby is not a random collection of lessons. It is a consistent system of materials where each level logically builds on the previous one. We aim to make the learning process clear, structured, and practical.

Experience and Expertise
The Lumiruby team has over 8 years of hands-on Ruby experience in production environments. During this time, we have worked with:

  • internal services and process automation
  • ETL scripts and large data processing
  • monolithic and modular systems
  • performance optimization and profiling
  • application deployment and maintenance

Lumiruby materials are built on real cases, working approaches, and practical scenarios. Our courses are taken by developers at different stages — from those starting with Ruby to those working with production code who want to organize architecture or improve performance.

Professional Activity
The Lumiruby team actively follows Ruby updates, explores new language features, and evaluates tools within the ecosystem. Materials are updated in line with modern Ruby practices and ongoing language development.

Mission and Values
Lumiruby’s mission is to make deep Ruby understanding structured and accessible through consistent learning materials.

Our values:

  • Structure — learning should be logical and progressive.
  • Practice — every concept is supported by code examples and exercises.
  • Depth — we explain not only “how” but also “why.”
  • Relevance — materials evolve together with the language.
  • Transparency — users can review course structures and sample materials before purchase.

Lumiruby is a platform for those who want to build Ruby skills systematically, with a clear understanding of the language’s internal logic and capabilities.
