I was in a similar situation a few years back. I wasn’t only focusing on CRUD, but it was a large part of my work too. Mostly working on web-based SaaS projects.

I started learning infra via AWS CDK (TypeScript). And by osmosis learned a lot about cloud native application architecture. Which changed my way of creating web apps entirely and rejuvenated my love for software. Still going strong 5 years later. Now with much stronger focus on platform engineering and not working on features much.

Looks like I'm in that path you've already passed. From January I have to learn CDK because my current job requires me to do. Also planning on to obtain those AWS Cloud Certificates.
