What Does A Delphi Programmer Do?


Delphi programmers use the programming language Delphi to create software solutions and applications for platforms like Windows, Android, Linux and other platforms. They develop and edit applications in Embarcadero Delphi, an integrated development environment (IDE). So, what does a Delphi programmer do and how much do they make?

What is Delphi?

Delphi is a high-level programming language that was developed by Borland to support Object-oriented design. This language is able to incorporate the low-level and assembly-level language codes and generate machine code for operating systems like Windows, iOS, Android, etc.

One should also note FireMonkey when talking about Delphi. FireMonkey is a powerful app development and mulit-platform framework created by Embarcadero for use in Delphi. The aim of this platform is to build multi-device applications for the operating systems mentioned above as well as getting them to app stores fast.

Delphi offers optional support for the Skia graphics library, an open-source 2D graphics library.

One of the biggest advantages of Delphi is its fast compiling speed and clear syntax, which leads to readable code. Programmers are therefore able to write large code-based programs that are able to run on limited resourced machines.

Other advantages of Delphi include:

  • Support for SQL databases
  • Communication and data exchange with C++
  • Adjustable VCL framework
  • Minimal maintenance
  • Single codebase for all platforms 

Programmers also use Delphi to create stable and compact back-end web services and microservices as well as to write Azure and AWS Lamda functions (even targeting the web browser is possible with Delphi!).

Most recent release (Dec 2022): Delphi RAD Studio 11.2 Alexandria (with additional language features).
