Mubasher.info is a leading financial markets analysis and information producer. I led a team to implement an integration layer, one of the corner-stones of their core platform backbone. The layer streams back-end data to critical internal and external clients. Newly created content is pushed from the platform across the rest of the Mubasher network. A message-oriented architecture is implemented utilizing Enterprise Integration Patterns. The Mubasher.info content platform pushes content over to a message broker and specialized “consumers” are subscribed to the broker to receive the streamed content in real-time. The content is then pushed over to the rest of Mubasher network, which features multiple systems with different sets of requirements.
Pull API was provided as a REST-ful resource in XML and JSON formats. IFrames support was also implemented in a re-usable fashion, where each client may receive a fully customized version of the IFrames through the admin and by utilizing the power of clean markup and custom stylesheets.
API clients include mission-critical internal clients (Mubasher network), a dozen banks, and several popular newspapers and portals.
Key technologies: Java, RabbitMQ, AMQP, Spring Integration

I led the development and implementation of the Online Program Application System for the United Nations Development Program in Spain. OPAS was developed to help the UNDP-Spain MDG Achievement Fund make their yearly strategic plan, involving managing and prioritizing different projects from around the world. A total of €500 million is assigned and distributed amongst these projects every year throughout OPAS that implement different stages and rounds for qualifying and selecting the projects. It features a modern, highly efficient web interface with integration with the UNDP network, resulting in a completely automatic, hassle-free system with users from different UNDP offices all over the world. It enables a higher level of information for decision-makers a few mouse-clicks away. It also features custom reporting tools to allow decisions-makers to literally “build” custom reports by mixing and matching any data in the underlying relational database with applied filters, sorting, etc. OPAS is written in PHP, using the Drupal framework as the basis. All customizations are implemented as reusable Drupal modules.

I designed and led development of a Central Authentication Service (CAS) that allows different websites and applications to share their user bases. This enables end users to use a single account across all integrated applications. CAS integrates with very busy websites, requiring extreme reliability and performance. This is achieved by implementing replication logic in CAS instances on top of MySQL replication.
Key technologies and protocols used: Zend Framework, SOAP, PHPUnit, MySQL.

I led development of a system for emergency routing and dispatching of vehicles. It consists of many components, including GIS, Asterisk telephony integration, and implementation of server-push (Comet) technology for supporting full duplex communication between the server and the client. It is written in PHP, and uses open source KaMap! as the basis of the GIS component.
