Worked on the Shopify/rails repository to enhance the reliability and correctness of background job processing by addressing issues in ActiveJob deserialization. Focused on ensuring that timestamp fields such as enqueued_at and scheduled_at were accurately preserved as Time objects when ActiveSupport.parse_json_times was enabled, preventing them from being set to nil and eliminating related data artifacts. The solution involved targeted Ruby on Rails backend development, with changes implemented across two commits to improve job scheduling accuracy and data integrity. Leveraged expertise in Ruby and backend systems to deliver a robust fix that maintains consistent time handling throughout the job processing pipeline.
