Worked on the Shopify/ruby-lsp-rails repository to enhance the robustness of the Ruby LSP hover feature and improve database indexing. Addressed a bug where index columns were inconsistently handled as Arrays or Strings, ensuring reliable processing regardless of input type. Introduced a new unique index on the users table to strengthen data integrity and refined test coverage to reflect these changes, focusing on accurate assertions and index sorting. Utilized Ruby, Ruby on Rails, and test-driven development practices to deliver maintainable improvements. The work reduced regression risk and enhanced the developer experience for Rails projects integrating with the Ruby LSP toolchain.
