Hi Johnny,
I have successfully reskilled/upskilled pro-code (Java/JavaScript) and other Low-Code platform developers like Camunda.
One of my ex-colleagues was trained in both Mendix and Outsystems. He told me the platforms have similarities that allow people to switch faster. The people I mentioned above are the ones who feel confident solving the more technical side of the Maker spectrum.
The best Maker I ever trained was a lady who studied economics in Prague, she was able to combine her trained technical skills with her creative skills. She was blogging and had a gift for working with people. She shifted without effort from the technical role to the BA/PO role and back.
Purely high-code developers will need to get used to the velocity of creating applications using Mendix. At first glance, they will be sceptical that Low-Code can be powerful enough. But once they grasped the power, they liked it. (yes, and sometimes they still mention that they can do a thing in the code with one line, which takes 3 to 4 actions in Mendix)
