I not only have a deep systems development background, I was also a founding owner of a Unified Messaging company and have a lot of depth of knowledge in softswitch technologies and VOIP communications. I have experience in this space with Lucent Technologies, Nextel Communications, MCI, Cisco, Vonage and others.
Here is an excerpt from my resume (on file with Freelancer) to prove the point further.
Virtual Network Company/License Technologies, Inc. – Marketing, Selling, Implementing and Providing Customer Support for a New Convergent Communications Product: As a joint venture partner and VNC/LTI Board Member, Mr. Grijzenhout led a PCS team that assisted VNC/LTI in marketing, selling, upgrading, implementing and supporting their CASPER convergent communications product on a global basis. Project work includes assisting VNC in obtaining joint venture capital; defining and building ASP service bureau and turnkey solution sets for different customer markets; marketing and selling the product to these markets; defining and building a supporting Network Operations Center and Customer Support Center for supporting the system and its customers; improving the product through structured version releases; and implementing the product at customer sites.
My $250 bid is a starting point - will need more information to define full scope of project further. I won't be your cheapest bid, but probably your best. Regards, - Dan
