With LLMs, the cost structure is credits/tokens all the way down. This month, I built a tool to help you price your service credits or plans at https://aitokenpricing.com.
I also did a write up of PRDs and using Railway to build apps on my blog at https://aftercompsci.com.
I'm working on https://mimicmarketer.com It allows you to define different personas that you can then test marketing on. This allows you to see how different personas will interact with your marketing. Currently, it has a feature that allows you to define basic personas and test them against two types of copy, as well as a tool that grades your email subject lines and bodies against a generic persona, assessing the likelihood of user interaction with the content.
My other project is https://eggexplorer.com This is a site I wish I had when building out my flock of chickens. It allows you to see the different characteristics of chickens and which hatcheries sell each different breed. You can also see which hatcheries sell hatching eggs for each breed as well.
This is an interesting idea for a services business; it's been done a lot with apps and sites, so DevOps logically makes sense. Having a maintenance retainer like you mentioned in another thread would be a great add on and hopefully some nice residual clients. Best of luck!
He's a legend, I remember in our Graph Algorithm's class our "text book" was mostly composed of the articles that he had written. Glad to see UCI representing here.
I'm currently working on a weekly curated newsletter of Florida Man content, http://floridamannewsletter.com as well as a personal blog about my projects and devops.
