    Specializing in Server Administration, Configuration, and Deployment

    United States - Last active: 6 days 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.

    Security-focused IT Admin & Developer

    United States - Last active: 10 days ago - Tests: 1

    I worked as senior software developer for a high-tech security corporation for 2 years (and still do consulting with them) and have been a developer for 6 years. I was responsible for their security audits and testing of their SaaS apps. I developed many cryptography-focused applications and wrote dozens of integration projects for cryptographic hardware tokens. I'm familiar, and up to date, with modern hash schemes (ie. SHA2, MD5), symmetric/block algorithms (ie. AES), and asymmetric algorithms (ie. RSA) and best practices. I practice secure programming in all of my projects and always follow best practices to ensure the final result is of the highest quality. I'm well-versed in PHP, HTML5, CSS, JavaScript (including jQuery, Angular, and Node), Bootstrap, PhoneGap / Cordova, WordPress, and ASP.NET. I also run a security-focused blog (https://joscor.com) and provide security audits for large state agencies in the area.

    Senior web developer

    United States - Last active: 10/25/2013 - Tests: 8 - Portfolio: 5

    Over the last 15 years, I have developed a wide range of websites using HMTL, CSS, PHP, and MySQL including sites for startup companies and small corporations. My core competency lies in complete end-end management of a new website development projects, and I am seeking opportunities to build websites from the ground up for you or your business. I am overly competent in database management and have superior knowledge of internet security from experiences from both ends of the spectrum, I have been a hacker in the past and now use this knowledge to better my penetration testing skills.I have many tools that I use to offer clients that guaranteed the most in depth penetration test of their websites. I charge $125.00 for the test, along with a very in-depth compliance report that will explain all vulnerabilities found to you the client. When you hire me for just programming, not only can you rest assured that you will automatically get a secured script and you will not have to worry about sql, xss and csrf vulnerabilities from any part of the scripts that I write. Security is my main focus when writing a script! I have skills in jquery animation, animations with new technology such as adobe edge currently in prototype stage (which will most likely deprecate flash), I have worked on almost every type of website there is from database driven cms, to static html, from real estate websites to javascript driven penny auctions, I have created gaming websites such as knightcrusaders.com, and I also offer server tuning for those who have dedicated servers and find that their websites are just moving to slow, I can optimize queries, tune mysql and php. Again I do have have over 15 years of experience so if there is something I have not listed feel free to ask and I will let you know if I have the ability to do it! I have taken several of the odesk test in order to ensure the client that I do know what I am talking about, I am in top 20% in a few categories which is by far not an easy accomplishment.
