    Information security expert

    United States - Tests: 2

    The most trusted security analyst on Elance! I offer world-class incident response, malware cleanup, and other assistance related to hacking / malware attacks. --- My expertise lies mainly in incident response and in reverse engineering / malware analysis. This means I can go in nearly blind and still quickly determine the source of an intrusion and how to fix the vulnerability. I can analyze a malicious artifact to determine its purpose. I can also apply my strategic experience to assess future threats. This is my normal work cycle for incident response clients: - get access information and begin investigating the server - perform triage / rapid removal of malicious and compromised files - keep track of all actions performed, and conduct live chat to inform clients of my progress (timezone permitting) - work with clients to keep monitoring for future hack attempts for the coming weeks and if possible, find/patch the vulnerability that allows the hack I will not accept payment if I can't finish a job to a client's satisfaction. My passion is for fighting malware and cyber criminals, not for taking money for quick and temporary solutions to a problem. I have successfully eradicated malware and secured the following platforms: - OsCommerce - Cre Loaded - CS-Cart - PrestaShop - Magento - Wordpress - Joomla - custom content management systems - PHPBB - vBulletin

    Petr B.

    Senior Developer, PM

    Russia - Tests: 5 - Portfolio: 2

    I have strong background in UNIX/Linux software development, Master's Degree in Computer Science. I worked on Enterprise high-load distributed hosting automation systems as a Team Leader (3.5 years in SWsoft, Inc., now called Parallels). For the last 6 years I'm running my own small software development business in Russia with primary focus on Python/Django apps. Not pure Web but often involving integration with hardware (Proximity Cards, Sensor Screens) or external systems like Payment Processing, SMS Gateways, GABRIEL (Airline Reservation System), etc. I can take an idea and turn it into a working business, through all the intermediate stages. Also I have experience of investing my own funds in my projects, so I feel the difference between "perfect code" in a month and "good enough" code that increases the revenue right now. Nevertheless, my code is very good: no copy-paste, always written with performance, flexibility and security in mind, etc. On oDesk I'm looking for (and actually find :) interesting projects with a sight on long-term fruitful cooperation. I'm also open to smaller activities (e.g., consulting) where my knowledge can be helpful.

    Multifaceted Virtual Assistant. Business support branch

    Sweden - Tests: 17 - Portfolio: 4

    My previous line of work led to the start of a VA business. My goal is to work with what I like and keep up the trend of various tasks. The rate described is my lowest rate, which I usually apply because I sometimes like to do assignments to keep my skills at a recent level, and then that rate apply. On the other hand could other duties require a higher rate. My VA role is one of the multi-skilled, or multifaceted as I use for marketing since I've learned a lot of different skills during the positions I held. I'm very service minded, as I started out as a cashier and office girl and had the privilege to work with people with genuine feeling for service. I find it likable and I also think it makes sense to keep a service minded attitude towards customers. If you see someone without a smile - give them one of your kind of recaps what service is. Additionally to the service offered in the line of work, that is. Later on I've for several years each, held positions as sales secretary, school secretary, administrative consultant, application specialist and web/system developer. Besides having extensive work experience, the studying of sociology, psychology and computer science at an academic level constitutes useful knowledge. Still today I feel at home in almost any constellation of work, I like to do repetitive tasks from time to time, and challenging tasks from time to time. Work satisfaction is important to me, and it means delivering good results, to be of benefit to the receiver. For myself the help and learn part goes a long way. One other thing to mention is that I learned to type at an early age. That skill has been both useful and fun during the years. Besides skills in service and typing, I'm interested in languages, both human and computer. Regarding human language, I write with a fine imagination, do my research and have a splendid vocabulary. Regarding computers, I like to make life easier for end users, and I also focus on usability. Regarding both languages, I also like to enhance the experience for the reader/user. Oh, I nearly forgot (if you're still reading this short essay that is), I also do some graphic designs from time to time. Web design, Logo designs, Business Cards, Newsletter, formatting in Word, layouts in PowerPoint and so on! We need beautiful things! Cheers!
