I'm the managing partner / director of Declarativa, an european information systems development company; managing partner and CIO at RentingPoint, the first portuguese rental marketplace; and a partner at BookMARC, a bibliographic systems developer. I also founded Servisoft, a portuguese distributor for Mac/Windows products, which I left in 2008.
I'm also an (Invited) Associate Professor at University of Minho's Information Systems Dept, where I teach the Programming Paradigms and Web Programming courses, and a member of New University of Lisbon's AI Research Center, CENTRIA
I love squeezing extra functionality out of existing declarative models, to make their use more productive for practitioners - naturally starting with my own development teams. For over a decade I've explored this concept with others in the realm of the development of interactive user interfaces wrapping "back-end" applications, designed themselves around substantial declarative data structures. The three last iterations are Declarativa's Web Application Maker system (web interfaces for SQL database applications, now supporting about 30 custom web information systems in use in several companies and organizations), XSB Inc.'s XJ system (Java Swing GUIs for Prolog systems, supporting several knowledge management tools in use at the USA's DoD), and RegionDoc, a workflow/document management platform..
