serverless-ai-fitness VS blog-crossposting-automation

In my fitness app, premium users get access to custom workouts generated by OpenAI. In my Step Function workflow that creates weekly workout schedules, I check the subscription level of every user and add a logic branch based on their subscription level. If they are a free user, the workflow will pull from a cache of existing workouts. If they are premium, then their data is passed to OpenAI to build the custom workouts.

I'll continue iterating on this design. The next big milestone is lifting this to its own domain and putting it behind a subscription model (it is SaaS, after all). But right now, you can access it and use it for free at fitness.readysetcloud.io or you can check out the source code on GitHub.

An AWS Serverless Hero, Allen Helton, did just that and wrote a detailed post about it.

If you want to see an implementation of this function, you can see it in my serverless-ai-fitness project. It is used in a Step Function workflow to build a workout with the equipment I have available in my home gym. It also creates a warmup and cooldown specifically for the generated workout.

This is open-source! If any of it excites you and you want to contribute, please check it out on GitHub! Feel free to fork it or open up a pull request.

So I added an EventBridge rule to the function and now I can send an email with a simple call to PutEvents. Here's an example taken from a Step Function workflow definition in my workout generator.

I am thrilled to take "workout building" off my plate. It's something I've enjoyed for a long time but I'm ready to have someone else do it for me. This was a fun project to build and I hope you take it and run with it. It's fully open-source and available for a PR!

In essence, his solution works like an automated assembly line for your blog posts. Once you write a post and commit it to your main branch on GitHub, AWS Amplify verifies the content and if everything checks out, a Lambda function retrieves your post and sets a workflow in motion. This workflow simultaneously transforms and publishes your post across Medium, Hashnode, and Dev.to.

This Lambda function is implemented in my blog crossposting app. It is called from a state machine to post articles to various publications. In this project, I created a Lambda function to generate payloads specifically for this function to use as simply as possible.
