Worked on optimizing the Stripe Ruby Library by refactoring its loading mechanism to improve boot time and memory usage. In the stripe/stripe-ruby repository, replaced eager require statements with Ruby’s autoload for nearly a thousand generated resource, service, and parameter files, deferring their loading until first use. This approach reduced boot time and memory allocations, while maintaining production safety through a new Stripe.eager_load! method and Rails integration via Railtie. Regenerated codegen artifacts and addressed CI lint and typecheck issues to ensure code quality. Demonstrated skills in Ruby, code refactoring, software optimization, and cross-environment compatibility throughout the project.
