We plan to provide Delphi developers with the opportunity to gain knowledge in the new technology stack as part of ongoing project activities. New applications will be developed using C#/.NET on the back end and Angular on the front end. If Delphi engineers are interested in acquiring skills in this stack, we will be happy to support them and enable further involvement in other products.
