  • Metainfo
    Software Development Manager
    Metainfo 1996 - 1996
    Us
    MetaInfo's founder purchased a port of Bind (DNS) for Windows NT, productized it within a year by adding web-based administration, and thereby launched a $15M/year product that enabled an internet presence for all the Windows servers that came on-line during the growth of Microsoft's Windows Server business in the 90's. Microsoft responded with a version of DNS built into every Windows Server, but the funny thing is that not many people ever took Microsoft's version seriously, and so it never seemed to hurt business, in spite of everyone's anxiety.As a consultant for a client who shared office space with MetaInfo, I would cross their path, and eventually joined as a development manager during the delivery of DNS 2.0 for NT and Sendmail with POP3 for NT 1.0, later acquired by Check Point Software and Software.com.

  • Application Methods
    Consultant
    Application Methods Jan 1994 - Nov 1995
    Application Methods had a special relationship with Borland, and produced the sample applications that shipped with many of their desktop database & development tools products. I moved from L.A. to Seattle to join, after answering their short newspaper ad that mentioned a small firm seeking a database programmer.Performed small business consulting with Paradox, Delphi, VB, MS SQL, and InterBase. Largest projects included a bill of materials for a large machine manufacturer, and an audit tool used by Alaska's largest grocery store chain that reverse engineered call plans and automatically disputed vast sums of telco over-charges.We hosted Microsoft vs Borland product showdowns, and were active in local user groups where we generated leads for the consulting practice. I pioneered the use of Lotus Notes for project management with remote clients, and gave an introduction to Lotus Notes at Jeff Winchell's "PC Database Summit 95", where I presented alongside other luminaries including Joe Celko. Taught Petzold-style Windows C programming and Windows TCP/IP to Unix system programmers at Boeing.
