    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.

    Zachary Richey

    Software Developer specializing in Web Technologies

    United States - Tests: 2 - Portfolio: 3

    I believe in and try to adhere to the software design principles of not repeating yourself (otherwise known as DRY), creating cohesive modules, keeping data duplication to a minimum, and creating clean well structured code. I am experienced in Python, the Flask python library, SQL, MySQL, and C#. I do my best to do the job right the first time, by ironing out the design of the software before starting and considering software development best practices in my work. I've also spent a good amount of time cleaning up after the mistakes and bad practices of other coders in my time back on Elance. So my goal is to leave my clients with code that isn't riddled with bad design decisions, bugs, security holes, and other problems that would likely require a full rewrite to fix in the future.
