## Dave The Software Barbarian has been around for quite a while now. Starting in the mid-1970s, Dave spent most of his time on DEC minicomputers at the University of Delaware in Newark, Delaware, working for the Education Department on project DELTA, and then for the Electrical Engineering Department helping to keep their UNIX systems running, and also writing software for EE professors and creating C-based 2D and 3D graphics libraries. Before graduating with a BS in Electrical Engineering, he began working at DuPont, building CAD systems used to design their chemical plants and support their existing legacy of Chemical Engineering know-how. After graduating in the early 1980s, Dave started working at Bell Labs in Holmdel, New Jersey doing UNIX system development, including ports to new hardware platforms and helping other employees write software - as well as expanding his computer graphics range. During this time he got his Masters Degree in Computer Science at Rutgers University. Bell Labs was undergoing significant changes with the breakup of the AT&T. That and the allure of UNIX workstation technology, gave him the itch to look outside. He found himself at Interleaf in Cambridge, Massachusetts and became a WYSIWYG document authoring system developer, focussing on reworking their font subsystem capability enabling them to do build and clean up screen and printer fonts, add high-end typographic features, and extend graphical rendering with outline fonts. While he was there, he also became a father to a daughter and son. While there, he started teaching programming at Interleaf, helping coworkers begin to learn Object-Oriented programming as it was just beginning to become generally available to the business mainstream. At the end of the 1980s, Dave had left Interleaf to head to Lexis-Nexis in Miamisburg, Ohio where he architected their new caselaw fabrication infrastructure, applying SQL to raw court transcripts. Once he got them going, in 1990 he switch over to Anderson Financial Systems (no relation) and built the infrastructure for an Object-Oriented Securities Trading System for the First National Bank of Chicago on the NeXT platform. He liked the NeXT and Objective-C so well, that he started Thirtieth Century Software on the side to build his own Object-Oriented Project Management software (after showing off the prototype, he was bought out.) In the mid-1990s, Lexis-Nexis decided they wanted Dave back in Ohio, this time to develop several internal-facing tools built on Internet-enabled technology. He extended the existing fabrication infrastructure he had delivered previously, built a Back-of-the-Book Hierarchical Index Generation system for multi-volume legal texts, and architected software to manage intellectual property for use by large legal clients. Meanwhile, at his new personal company Flying Monkey Software, he developed services for the NeXT community and in 1997 created the CGI-Gateway software for BuyItOnline.com, one of the first e-commerce companies on the web. In the late 1990s, Dave began writing his Geodesic papers, applying mathematical invention to physical architecture and CAD software for designing software. He moved to Tampa, Florida and with a friend partnered to form TekStar International, offering the TekCAD product, and TekKit components they designed and marketed for architects to build scale models of TekCAD designs, and for students to use for building geometric models. Dave formed Eymiha Corporation a few years later to continue to development of TekCAD when his partner passed away from heavy metal poisoning. During the early 2000s, Dave began working at TCI communications, now Syniverse, developing software to settle the national and international use of telecommunication infrastructure by mobile phone users. As more people bought phones, the business boomed. In the mid-2000s, he moved to Cincinnati, Ohio to help care for an ailing family member. He joined Professional Data Resources, now Ascendum, as Software Consultant and writing web apps for the Kroger Company, SOA for the Great American Insurance Group and writing mailing systems for Fidelity Investments. Dave discovered Ruby and Rails when he moved back, and got to know the Cincinnati Ruby community. As this association became stronger, he left Ascendum to work as a consultant at Edgecase (now Pivotal Labs via Neo), writing home automation software for Ingersoll Rand, Internet management software for ICAAN, and Mobile Device Portals for AT&T. Towards the end of this period, Dave discovered the Meteor JavaScript framework and charge into it. When Neo fractured and closed it's Cincinnati office in 2014, he went to work at Differential and designed and wrote Web-based 3D software in the new closet software design system for Organized Living. In early 2015, he got the itch to use Meteor in a new startup and went to work at Barnburner, Inc as their CTO to build recess.io, a product that provided group discounts for use of private event facilities. Great software is sometimes paired with poor management, and recess went into a lull. So looking for a new gig, Dave joined Callibrity in mid-2015 and has never looked back. While there he's done work on Kroger's Click-List product and their pharmacy expansion project, and on payment and loyalty systems for International Purchasing Cooperative in Miami, Florida. He's also taken responsibility for Callibrity's web site development.
