AWS Expert - Review and Edit Lambda Functions

I need an AWS Pro/Python developer to:

* Review + Edit Python code of 3 existing Lambda functions
* Prepare the zip package of a library for a Lambda layer (for one of these functions)

I will provide the code I currently have that we need to update so the output is more accurate. It's not the goal to rewrite the code from scratch or self-invent what you think the functions need to have.

These are all AWS Lambda functions (under 100 lines each) with a straightforward approach. They work, it's mostly about refining them. I have highly specific instructions for what the code must achieve from here, I've been testing them thoroughly.

For one Lambda function, I need the zip package as well, so I can use it as a Lambda layer.

* Previous developers caused a massive backlog, so I need someone who takes small tasks like these as seriously as big projects. Ideally experts from Australia or Europe, this task shouldn't take longer than 1 hour to complete for an experienced Python developer.

BUDGET: €40 (not to be exceeded, otherwise simply don't respond).
