    Senior Developer, PM

    Russia - Last active: 3 days ago - 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.

    Filemaker Business Systems Developer

    United Kingdom - Last active: 2 days ago - Tests: 5 - Portfolio: 4

    Experienced IT consultant for over 15 years, moved into developing Filemaker solutions over 5 years ago. Experienced with Filemaker 10-13, in Pro, Pro Advanced, Go and Server, including Web Direct. Presently the managing director of a retail company with a number of sites, most of my development has been for my own business and personal needs. I have also recently started Freelancing in Filemaker via oDesk. Current open projects include - Full multi site "simple EPoS till system", reporting to a centrally hosted server for reporting to iPhone/iPad. This "easy to use, but complex in design" system allows for near real time checking of 3 cash registers in 3 different sites remotely via iPhone. All built on Filemaker technologies. - Over 2500 member database, tracking membership of over 200 "groups" and associated subscriptions. This database is shared online to ~20 users with differing access and usage requirements. This has involved separate development, layouts, scripts, for each role. The information in this database now spans back to 1994, when it was kept in a number of Paradox for DOS databases, one for each year. These were ported, via DBase and Excel into a "Filemaker conversion package" that manipulated the data into a single entity. - Work with an external Funeral company to assess requirements and formulate a design for various business needs. This is ongoing work. - A number of simpler systems to track cash take, banking, travel expenses, stocktaking, etc. Some of these are hosted for multi user input. I mainly try to develop Filemaker solutions to appear as fully fledged client applications, with complete control of the user experience. I hide the 'out of the box' Filemaker menu system, and have developed a number of equivalent controls to navigate records, perform finds, or display the records being shown. I very much believe in the Apple 'usability model'. The 'simple to use' EPoS system I have developed requires no documented staff training to use.
