    Filemaker Business Systems Developer

    United Kingdom - Last active: 1 day 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.

    Interaction Designer, IA, UX Consultant

    Ukraine - Last active: 3 days ago - Tests: 20 - Portfolio: 11

    Me and others of my profession have a good understanding of how people seek information, how they react to different elements of digital products, and how they use such products. With this knowledge, I can greatly improve your website or application so users would love it more and it would serve business goals better. What you get when having a good interaction designer in the team is that your products are not made of standard decisions. Instead, I try to anticipate how the user will really use the product, how he would expect it to work and be organized. Then I can come up with solutions that suit this exact case much better. Work of an interaction designer greatly reduces the risk that the team would develop a feature (or product) which customers won't like and won't use. I follow a design process described in Jesse Garrett's book "Elements of User Experience". At the level of strategy, I discuss business and user goals with the client. Then I use my knowledge of Information Architecture and Interaction Design to determine what features and content the project should have to meet those goals and structure the features and content in a way the user would expect them to be. Then I build an interactive prototype - a set of detailed wireframes of every page, linked to each other and imitating the behavior of the end product. I use Axure for this purpose. When approved, the wireframes should go to a visual designer. This process is much better than putting visual design first and thinking how you should make something eye-catchy, before figuring out how users will interact with it and devising best ways for it to work. It's better that I start my work early on, when there is only a concept. This way I can put your project onto the right track from the beginning. I'm 7 years in web development overall. I have a background in project management, SEO, content management and linguistics.
