    Software Reverse Engineer

    Russia - Last active: 5 days ago - Tests: 3 - Portfolio: 1

    I am an HPC (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 I have somewhat outdated formal training in cryptography (and cryptography related math) but I am definitely not an expert in the field. But here I am looking for fixed price software reverse engineering jobs to keep my skill fresh. Reverse engineering of firmwares for any kind of devices and Molebox problems are welcome.

    Ethical Hacker and Digital Forensic Investigator

    Mexico - Last active: 12/03/2014 - Tests: 3

    For the past seven years, I have been learning about the information security world, working as an CEH (Certified Ethical Hacker). With some of my co-workers, i have participated in a lot of projects, strictly focused on Information Security. Also, as we evolve and grow in this area, we have trained ourselves in Forensics Sciences, attending clients who need to know what happened after a contingency. I consider myself a self-taught person that likes to grow and that is not afraid of challenges or difficult cases. At this moment my priority is to teach and so much to share the little knowledge I have gained over the years, as well as learn from those who have traveled a different path and with this keep on growing.
