PROFILE
Ethan Turkeltaub
Worked on enhancing Ruby code generation for the fern-api/fern repository by introducing abstract syntax tree (AST) support for methods, classes, modules, and RBS types. Focused on building robust AST nodes to represent Ruby method definitions, including parameters, visibility, and comments, and integrated these with the code generation pipeline. Expanded the system to generate RBS type signatures and improved handling of type parameters through internal refactoring. Leveraged skills in Ruby, TypeScript, and type systems to ensure safer, more maintainable code generation. Comprehensive tests were added to validate new constructs, laying a foundation for typed Ruby code generation in future development.
