Better way to handle background processing w/ uploads to s3

delayed_job.rb

# lib/carrier_wave/delayed_job.rb
module CarrierWave
  module DelayedJob
    module ActiveRecordInterface
      def delay_carrierwave
        @delay_carrierwave ||= true
      end

      def delay_carrierwave=(delay)
        @delay_carrierwave = delay
      end

      def perform
        asset_name = self.class.uploader_options.keys.first
        self.send(asset_name).recreate_versions!
      end

      private

      def enqueue
        ::Delayed::Job.enqueue self
      end
    end

    def self.included(base)
      base.extend ClassMethods
    end

    module ClassMethods
      def self.extended(base)
        base.send(:include, InstanceMethods)
        base.alias_method_chain :store_versions!, :delay
        ::ActiveRecord::Base.send(:include, CarrierWave::DelayedJob::ActiveRecordInterface)
      end

      module InstanceMethods
        def store_versions_with_delay!(new_file)
          store_versions_without_delay!(new_file) unless model.delay_carrierwave
        end
      end
    end
  end
end

How can I use this in my uploader?
