David P. Discher

Summary

Web Application Developer and UNIX System Administrator
Aspiring FreeBSD Kernel Developer
Desiring a Design/Architect position in embedded systems or object storage

David P. Discher has a very aggressive and entrepreneurial personality. He is very passionate about technology. He would like to work closely with the details of the project.

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, OpenStack, and FreeBSD/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.
