I am a MCD+, and ZCE, who runs a small ecommerce consulting firm, specializing in Magento.
You can see, here a couple of modules that I have open-sourced as a way to give back to the community. My two favorite are the Kit Product (built on grouped product but specifies fixed products and quantities), and Simple Configurable (which adds products together in more of a standard thought-process).
I am a Christian who desires to please Jesus in everything that I say and do in life. As such, this is my theme verse for my questions and answers on this website: "And whatsoever ye do, do it heartily, as to the Lord, and not unto men;" (Colossians 3:23).
