    Software Reverse Engineer

    Russia - Last active: 1 month ago - Tests: 3

    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 I have somewhat outdated formal training in cryptography (and cryptography related math) but I am definitely not an expert in the field.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.

    Delphi developer

    Bulgaria - Last active: 2 days ago - Tests: 11 - Portfolio: 5

    I believe that freelancing is the best way to gather experience and improve one's skills, while giving the most flexibility to both workers and employers. I have developed in Delphi (versions 5,6,7 to XE6), C++, PHP, SQL and others. Over 4 years, I was responsible for managing computer and paper based examinations at the British Council in Bulgaria and writing software for the above. This has taught me the importance of keeping to schedules and deadlines, team-working and communication. As a Computer Science graduate, I have very good knowledge of computer systems, OS, networking concepts, information security, etc. I also have some experience with GPS, Garmin products, Google Earth/Maps and cartography.

    Russia - Last active: 2 days ago - Tests: 5 - Portfolio: 3

    Python is my favourite language and I use it for implementing various system utilities and web backends (with Django framework). I am a server-side guy but despite this I also know how client-side (JavaScript, etc.) stuff works. Besides Python I like functional languages: Haskell, Ocaml, Lisp (Scheme) but they are just my hobby.

He kept me updated with his progress the entire time and responded quickly any time I needed him. His expertise in MATLAB and Partial Differential Equations was very impressive. I enjoyed working with Muhammad and have complete confidence in him when he says he can complete a project. He was the perfect freelancer for me.
