Part Time developer for API backend using AWS / Lambda + Building landing pages

I'm looking for a long term developer who can help me with my backend setup to build a system where I can collect leads using API.

You need to be familiar with AWS as I'd like to use AWS + Lambda to set this up. I have a dummy version set up, but I need a more advanced version with constant further development.

The goal is to capture leads through API on my own landing pages. This would mean that a user lands on my landing page, goes through the flow, signs up with their email (we then store this email), and then we use a ping tree with API to sign the user up to one of the products in the ping tree.

If this is something you can do, please send me a message with your desired rate.

Also, please send some examples of your work if you have any with some background info about your experience.
