    Software Reverse Engineer

    Russia - Last active: 1 month 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 I have somewhat outdated formal training in cryptography (and cryptography related math) but I am definitely not an expert in the field.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.

    Delphi developer

    Bulgaria - Last active: 1 day 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.

    Python System/Web Developer

    Russia - Last active: 1 day 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.

    Valentin G.

    Software engineer (C/C++, obj-c, Python, Matlab, R, ML algorithms)

    Belarus - Last active: 2 days ago - Tests: 7 - Portfolio: 5

    The last 5 years I have worked mostly as a C and C++ developer in a field of process automation and control (SCADA). Familiar with OOP and TDD, Design Patterns and different methods of software development (waterfall, agile). I have a good experience in the development of multithread client-server applications, windows services, dll-s and cross-platform libraries. One of the specific features of my job was writing readable and easy-portable C-code covered with tests.Another interesting feature is working in small groups dealing with frequently changing goals. The major benefit of this style of work is a great experience on all levels of software development process (from project design and requirement development to final tests). Besides, I have a great interest in the research of new technologies and IT science related fields.
