So, you've been building a few Lambda functions here and there to do some administration, maybe to ship your logs or respond to CloudWatch alarms.

First, congratulations on your achievement.

Next, you'll need some tips about how to make the most of the execution time you have available and be able to use the execution model to your advantage.
