Being polyglot developer is not easy, since most of the time you’ll have to acknowledge there are tonnes of frameworks out there being used together in one whole giant project environment, even in mobile apps itself, since business people would want to have a “one app cater for all” frameworks.
There are actually a lot of times where I have to look at Laravel source codes, Java Maven and Ruby on Rails projects. Kinda sounds scary at first, but this is the way projects are architected. MICROSERVICES architecture for scale.
