Hi, I'm a Delphi programmer since version 2.0, and since then I've done numerous projects of all kinds with that language. I have worked with several databases, both client-server (Firebird, Interbase, SQL Server, MYSQL) or local (Clientdataset, Access, SQLite). I have developed components, many of them graphics. I understand the requirements of the project and I can do it with VCL or with Firemonkey. I develop with Delphi 10 Seattle, there should be no problems for it to work on Delphi 10.1 Berlin, and I do not think it necessary to use any additional components. You can trust me to do it as explained in the document, thank you.
