Hi as someone who employs and select developers i agree with a lot almost sayed but think of what are your strengths and where you are or better where your customers are. If you search for big enterprise projects spring boot is ok sql is must and html css as well. if you want to go more to internet related companies (like airbnb, what sup, facebook ) or similar (and not asia) then react is a must node js as well. The libraries tools etc which are used you need to adopt fast. If asia then VUE is a must. but if you like small projects with individuals or like wordpress or similar then you can learn php but i think in 2020 it is wasted time. Same for python in that area. and i also see that we often have problem that developer at least must understand docker docker compose better as it works with kubernetes ,.. just my 5 cents
hi this depends where you want to advance . If you want to work for an big aged company with a lot of legacy go the spring way (banks, insurances netflix etc ) if you want to go the new agile fast cloud way learn node js it is much more suited for cloud and micro service even spring cloud can do that as well but it is much more heavier
Hi i used Gatsby strap and other Graphql solutions. i would do an kind of backend where you do your umbrella and or data entry. (i would use meteor for that and do an Graphql service with its data.,..) then you can model all you need in JS and in react you show depending on your requirements. And for provisioning iAd do a kind of hook which does bring together the Gatsby template data and whatever they need. my solution would enable you also to provide some backend services coming from umbrella if needed. but maybe i got your requirements wrong. It is also possible to do all in Strapi,react and Nodejs maybe https://www.youtube.com/watch?v=Oc_ITwxiG-Y&t=4760s gives you a 2nd idea thomas
