Basically a ReSTifarian who's been in hibernation mode. I embrace the concept of hypermedia affordances, and have built various apps over the past 10+ years:
I'm learning modern Angular and React now (just finished surveying a Full-Stack JavaScript Course at Udemy based on LoopBack and React; May 2020), and I've also studied holochain, other cryptosystems and underlying principles (CAP theorem, ACID/BASE, SSI and DPKI, etc). You've got to combine atomic BEM with utility classes to scale your CSS, and don't do redundant accessibility labeling. You know the drill!
