I'm an early-mid career SDET/SRE. Currently building a full web app with rest AP integrations, looks great and works great. Lots of functionality, useful and being hardened all b/c of AI. It's going to be live with customers soon I hope.
AI is not a feature of the product. GTM will be interesting, have some good ideas.
It's really up to you to be clever. I've never used Js/Ts/node/these apis etc. I started programming as a non-cs engineer to automate stuff and then got into SWE. This is truly an amazing time.
