Delphi Coding Support

I'm seeking a UK-based, intermediary-level Delphi developer to help me with modifying/extending an existing suite of Windows desktop applications. It's a complicated project that requires good knowledge of GUI development (including use of TMS components) and ideally some understanding of maths/engineering. I am looking for someone with broad knowledge of the Delphi language up to version 11.3 and associated Delphi libraries. Finally, I want someone who can write clean and organized code within our existing framework as well as debugging existing codes. I expect the candidate to already have access to their own licenced copy of Delphi to version 11.3
