I am also a computer science professional with an established career of 20+ years focusing on management of computer systems, programming and data recovery. Because of my interest in open source computing I currently concentrate on technologies like the Linux operating system. In the past I worked extensively with healthcare informatics and electronic health record systems, using both Microsoft and UNIX platforms.

I provide data recovery services for HDD units suffering from logical failure. If you suspect such a failure *do not* run anything that will write data to the failed drive, or attempt to fix things on your own; doing this will reduce the chance of recovery. For details about my data recovery services, please contact me at (787) 531–6914 or
