    Specializing in Server Administration, Configuration, and Deployment

    United States - Last active: 1 day ago - Tests: 5

    I have been in the telecommunications industry for over 13 years and have worked as a consultant to major Fortune 500 companies in the past for both business and technology needs. I have a vast knowledge of anything that relates to the internet, both hardware and software realms and have worked on a variety of projects ranging from the simple to large scale transition ones spanning months at a time. I understand a business' need to get projects done right the first time and have always exceeded my clients goals. If they're not happy, I'm not happy. I have a dual bachelors degree from the University of Colorado at Denver in Business Information Technologies and Business Management. My Masters in Business Administration is in International Business and most IT skills I have picked up on my own or through various courses either online or at the local community college. I look forward to working with you and completing any projects you may have, from the quick fix to an entire server farm rebuild. I am also a word class back end programmer familiar with MySQL, Bash, PHP, Perl, and Python. Please, no front end design work, I don't have an eye for creativity (unless it's something simple of course). I look forward to working with you and any projects you may have for me.

    Software Reverse Engineer

    Russia - Last active: 26 days 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 I have somewhat outdated formal training in cryptography (and cryptography related math) but I am definitely not an expert in the field.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.

    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.

    Software Architect

    Greece - Last active: 04/28/2014 - Tests: 3 - Portfolio: 6

    I finished my degree, BSc Honours in Computer Science at the University of Leeds, England, at the age of 22. Since then I have had more than 15 years of experience in building large scale applications using Delphi, C++ Builder, Microsoft VB, Microsoft C++ and Microsoft C#. Other skills involve 3D programming with DirectX, OpenGL, and HLSL. I have a very good physics and mathematical background which allow me to easily develop physics simulation systems, 3D visualisation systems and deal with problem solving. I can easily program client/server multitier applications that involve network communications such as TCP/IP programming, SOAP and a lot of other proprietary and standard network protocols, such as POP and Web Services among others. All application programming at some point involves storing data in a persistent storage. I have been writing applications that span over from custom database development, such as binary tree/hash tree indexing units, to using ready made relational database systems such as SQL Server, Interbase, Oracle and Access.
