    If you are looking to have custom software built for your organization you are treading into dangerous waters. I will not say you have to engage with me (even though I want to) but you are going to need to find someone who is willing to help you through the whole journey and walk it with you. The truth is the world is filled with programmers and they will make all kinds of promises but very few of them have ever delivered business critical software. They are mostly good at doing what they are told and if you are looking at my profile you need someone to deliver your system to solve your problems, not create new ones. Working with clients to build their software is a partnership and that requires dedication and strong communication from both parties. You will see how I help form this partnership from our first meeting and how it will continue forward. You do not need your software to be just another failure story in the industry and I will not allow that to happen. I am more than happy to talk about software development with anyone even if you have no real intention to engage. Every conversation is a chance to learn more about potential future clients even if it is not you. I also really want you to avoid the mistakes that can truly cost you.
