    Consultant and independent researcher specialized in international trade, law and legal informatics (open data standards, entity extraction, knowledge engineering and artificial intelligence applied to law). During the last fifteen years I have worked as delegate of a chamber of commerce in Shanghai and London, contractor for Stanford Law School, and collaborator of the Scientific Affairs Office of the Spanish Embassy in UK (I can provide recommendation letter from the former minister-counselor who headed the office when I worked there), among other positions. Although born and raised in Barcelona, I have also lived in Chile, China, France and the United Kingdom. For the last three years I have been residing in Hainan, a tropical island at the South China Sea, close to Hong Kong (where I am currently studying an L.L.M. in Chinese Business Law). I work as a team with my wife, former executive recruiter at Michael Page Shanghai, who is a Chinese native speaker. We are fluent in English, Mandarin, Shanghai dialect, Spanish and Catalan.  less

    In the past several years I have built many Iphone and Android applications, with a focus on Maps, GIS, GPS, PUSH, and geospatial data as well as experience in information management and presentation. My core ability is complete engineering of mobile applications from the ground up, choosing appropriate database, logic, and UI technologies from the array of existing options. I have specialized knowledge in mobile sync and RESTful communicate with custom websites and existing social media datastores. I also have a good deal of experience building web applications (php-apache-mysql, ruby on rails) using Ajax, OOP, and Agile methodologies to build highly scalable websites, as well as design of technology infrastructure using cloud technologies (AWS, EC2, IrisCouch, etc) I architect and implement integrated mobile and server side solutions for projects involving mapping, GPS navigation, geospatial analysis, RFID, GIS, remote data collection, location aware API design or integration, offline functionality, and other custom location aware technologies. I am currently experiencing very high demand for my skills. Clients who find it challenging to pay my full hourly rate may wish to contract instead for a few hours of consulting or architecture design work. With a short time investment, I can add value by providing structure and direction towards building a solution the right way, rather than relying on uniformed design decisions of less experienced contractors. I can also assemble a team to fill the full needs of a given project as needed.  less

    I am a senior software engineer with over 7 years of experience. I prefer to work on ruby/rails projects but also have lots of experience developing windows software for audio/video processing in C#. Github: http://github.com/raeno My key skills: * Ruby, Rails 3, RSpec, Cucumber, Heroku, PostgreSQL, Mysql, NoSQL, MongoDB, * Javascript, Coffescript, HAML, HTML5, CSS, SASS * .NET 2.0 - 4.5, C#, WPF, XAML, WinForms, WCF, MVVM, MVC, ASP.NET, XML, SQLite * TDD, BDD, Continous Integration (TeamCity, Hudson), Nant, Rake, Git, SVN, Capybara, Nginx, * Amazon AWS (EC2, RDS, S3, ELB), Heroku, Engine Yard. I also have experience in UX, product and project management (was a head of development with 15 developers and two QA engineers in a my team) ===== Why you should hire me and not another $5/h developer? I think that quality is a key in a modern software development world with a lot of a crappy code producers and code monkeys. Thus I always try to achieve good test coverage and simple DRY design. And it's easy enough for me because i use TDD, continuous integration, continuous delivery and devops practices in my daily workflow. But quality is not only a code or design quality. I have seen many projects that were written very good in terms of code but they hadn't solved business problems. My point is that knowledge of a customer business domain is a key to better software. Being software engineer means for me not only to produce code that perfectly follow specifications but also to solve new business problems creatively. It's impossible to do if you haven't close relationship with a customer or doesn't want to listen him. That's why always use an agile approach with a daily progress tracking, frequent releases and focusing on a most important customer problems. OK, it's time to finish. If you still think that a you can better hire a ten Indian coders for my price - go and hire them. But when your project deadline start moving further and further and it all finishes with a buggy product and a spaghetti code - remember about me.  less
