Open source

I maintain a number of more or less popular libraries in Ruby ecosystem.

Rails tooling:

• store_model allows you to wrap JSON-backed DB columns with ActiveModel-like classes;
• ar_lazy_preload brings association lazy load functionality to your Rails applications;
• io_monitor is a gem that helps to detect potential memory bloats;

GraphQL toolbox:

• graphql-ruby-persisted_queries is the implementation of persisted queries for graphql-ruby;
• graphql-ruby-fragment_cache powers up graphql-ruby with the ability to cache response fragments;
• rubocop-graphql is a rubocop extension for enforcing graphql-ruby best practices;

Code quality:

• rubocop_director is a gem for preparing a refactoring plan based on rubocop and git stats.

Experiments:

• transducers-rb is an experimental implementaion of the transducer pattern for Ruby;
• applicative-rb is an experimental implementaion of applicative functors for Ruby;
• natural_dsl is an experimental DSL for building natural–language DSLs.

Also, I contribute to various open–source projects (Ruby on Rails, graphql-ruby, GitLab, yarp and many more).
