Technical Leader

July 23, 2010 10:10
David P. Discher has a very aggressive and entrepreneurial personality. His talents, skills and drive are often under utilized in large corporations. He much rather be involved in a small group or small to medium size company especially a startup. He would like to work closely with the details of the project. He believe that he would be a aggressive leader and manager, though wishes to stay close to the engineering and design aspects of the projects. Discher would like to work within a vertically organized project group, designing a system begin to end and seeing it through to release. He is especially interested in being intergal in the design phases of systems and projects. Discher would enjoy working on projects using open-source software or open standards in software development, web application or an embedded system. Projects taking advantage of Open Standards and Software like XML - SOAP, XMPRPC, XSLT/XSL, XHTML, CSS, MySQL, Apache, PHP, Perl, and Linux would be ideal. Recently Discher was reunited with his true passion - FreeBSD. He would ideally like to have a position which he working closely with FreeBSD and hopefully start contributing back to the open source community.
