    LINUX ADMINISTRATION: Whether your business needs a virtualization solution, remote administration, more secure and sophisticated software services, or simple, clean, and efficient publications or websites, I'll bet I can solve your problems quickly and on-budget. WRITING: Looking for great writing? Looking for someone with a strong tech background who is able to write clear, engaging text with the clarity and focus of a professional teacher? Do your company's software documentation and user guides need greater clarity? Is it time for a major update? I can help. Over the years I've written and edited enterprise software documentation, user guides, tutorials, and hundreds of articles. My careful attention to detail, experience and love for both writing and editing will ensure high quality output for written and desktop publishing projects. I'm familiar with Atlassian Confluence and other Wiki documentation systems. NOTE: As I use only open source software for my desktop publishing projects, my customers can both keep and easily reuse the original files.  less
