I work with the CSAM XDS, Infobroker and Medimaker products. The most resent products are built on Scala, Akka, Cassandra and non blocking I/O with back pressure.

During an internal reorganization, the work title did change. The daily work was however not affected. During this period, the automatic testing of the X7 products was greatly improved. I built a test system on VMWare ESXi and then Citrix XenServer with an iSCSI storage on OpenSolaris on a limited budget. The system is used for the automatic integration.

eCare AB was acquired in 2007 by the Finish company Mawell. Focus has been on Infobroker and XDS architecture. During the period, the technology, and also the work loads have advanced. The products on Solaris are transferred to Linux. Further, the products have matured with, e.g. SNMP monitoring support, administration GUIs and greatly improved.

Senior system architect at eCare AB and later CTO. I have during this time been the head system architect of the award winning Feedback system and the Infobroker system. Both systems are built in a JEE framework. Infobroker is fully clustered system without a single point of failure. XA-transactions with transaction recovery are used internally in order.

The Ph.D. thesis work contained modeling and computation of RF heating in toroidal fusion devices. The work was done in an international collaboration and competition. I was twice appointed as one of the Swedish delegates at the prestigious IAEA fusion conference.In the publications included in the thesis, the first self contained calculations of RF.
