Hello!
I'm a very experienced developer, but I'm new to Amiga development. .....
Thanks for any help as I'm really looking forward to getting my hands dirty pretty quickly.
Welcome to Amiga.org! It is always great to hear of any new developers coming to the AmigaOS/MorphOS/AROS community to do work. I hope you find what you are looking for, or can work with what is available and start developing for AmigaOS/MorphOS/AROS.

PortablE also compiles for multiple systems, based on AmigaE.
