I am a software reverse engineer: * Are you interested in analysis of software (or device firmware) you don't have source code for? * Don't know how to extract your own data locked in a proprietary data format? * You want interoperability with a proprietary software or online service? * a vendor or supplier locks you to their overpriced closed source solution? * A company is out of business and you need to migrate or to live somehow without official support? Contact me. Requests for reverse engineering of firmwares for any kind of devices and software for all operating systems are welcome. Background: I am an High Performance Computing specialist ( keywords: "super computers" / "number crunching" ) working mostly with huge Linux systems and math related tasks. I am also a scientist specializing in linear algebra. I have somewhat outdated formal training in cryptography (and cryptography related math) but I am definitely not an expert in the field.
