My job as a programmer is focused on creating web applications, that is making different languages and technologies coexist in the same place. Here is what I usually use in no particular order, regardless of whether it is a programming or markup language, a framework or a code versioning tool:
For projects requiring high degree of reliability and scalability, I propose Platform.sh as hosting and CI / CD platform: it allows you to develop in an agile and continuous way without your website or eCommerce risk of go offline. I you have a tighter budget but you do not want to give up on advanced infrastructure for managing deployments, I propose the combination of Wodby and DigitalOcean.
I try to experiment with new languages and technologies keeping in touch with a network of developer and non-developer friends: Coding-Gym, Programmers In Padua.
Do we work together?
If innovation is in your DNA.
