Long time in the tech field. More a Business Systems Analyst most times than a developer, but I wear both hats.

Things I have oodles of knowledge about:

• Shipping/Transportation Logistics

• International shipping

• Warehouse Management/Inventory Control

• CRM(Microsoft Dynamics, SugarCRM, quite a few different ERP's)

• Project Evaluation

• Technical Sales

• SEO/SEM/Targeted Content

• Lots about Roofing and Printing

• Rapid Learning Techniques

My preferred methodology is submergence aka out the airplane with silk and thread. Something very zen about having no f'n clue what you're doing, but knowing you will be skilled with it in a few weeks.
