Currently CTO at dotMobi, the Top Level Domain Registry for the mobile Web, Jo is responsible for product technology strategy, development and operations. Jo represents dotMobi at the W3C where he is an active participant in the work of the Mobile Web Initiative as co-chair of the Mobile Web Best Practices Working Group, and is editor of the Mobile Web Best Practice Recommendation and a number of other W3C documents.
Jo is also one of the founders of Mobile Monday London, which since November 2005 has grown to a major community and forum for professionals involved in the mobile scene.
Prior to dotMobi Jo was CTO at Flirtomatic where he was responsible for the specification and commissioning of the technology platform for launch.
One of Jo's main interests is the application of technology to the challenges and opportunities presented by the wide-scale availability of information, especially the difficulties faced by corporations and individuals in obtaining relevant information in a quantity that is appropriate to the information consumer's context. As part of this work he initiated the international XML-based standard for news "NewsML", and his work on the automatic categorization of news, using natural language processing technology.
NewsML is an important step in the development not only of technology for news but also of the way that news is conceived and reported by journalistic organizations. One of Mr Rabin's former colleagues described Reuters plans to start using NewsML as being the most important change in the company's production of news since it switched from using carrier pigeons to using the electric telegraph.
In the course of his work with Reuters he was CTO of Reuters Mobile. In this role he was responsible for formulating the company's strategy for the mobile age. Development of this strategy helped him develop and enhance his thoughts about use of information in context, with particular regard to the special challenges presented by mobile technology.
While with Reuters he spent a number of years in Silicon Valley acting as the company's technology representative on the West Coast of the USA, and working with colleagues in the Reuters Venture Capital (RVC) / Greenhouse Fund.
Jo has special experience of building large-scale, mission critical systems - gained in particular while responsible for the development of Reuters foreign exchange dealing network. While he was in charge of the development of this network, it carried over two trillion dollars a day in foreign exchange dealing, transacted between over 25,000 traders in over 100 countries. This network set a standard for reliable distributed computer systems, with every second of down-time representing tremendous exposure for the network's customers.
Before Reuters Jo worked for Telecom Gold, the pioneering electronic mail and on-line services organization. Before that he worked as a software engineer developing both high-level applications and software at the hardware interface.
By bringing together his deep understanding of technology with his understanding of the commercial application of technology Mr Rabin has a particular skill in acting as a bridge between technologists and company management. He is able to explain in terms that are appropriate to either side the other's point of view. His insights help to bring together a clear understanding of the role of technology in realizing the company's plans. They also help to inform those plans by clearly identifying the potential of technology and to the formulation of appropriate implementation strategies.
