5/2006 – 1/2009

Specification of new high-level IMS API (JSR281) on J2ME, released, reviewed, and approved by the Java Community Process, JCP.

Reference implementation of JSR281 integrated into Suns Wireless Toolkit (SW development kit).

Full-blown commercial JSR281 implementation on Ericsson’s R13 platform.

In addition to this I led the work of producing a Technology Compatibility Kit (TCK) for the JSR281 API. The TCK, is basically a large test suite, packaged into a test-harness together with a couple of network simulator applications which any implementor of JSR281 has to pass in order to be JSR281 compliant. Sort of a compliance tool. My work consisted of implementing the test harness framework and network simulators and supervising a group of 10 testers delivering around 1200 tests cases.

8/2004 – 5/2006

Linux device drivers for I2C and several other proprietary communication mechanisms.

Linux device drivers for E2prom, LED-control and fire central keyboard and LCD.

Wrote a Data link bridge application (PowerPC) which translates UDP/multicasting data to I2C data.

Implemented I2C multimaster drivers for HC12.

Designed and implemented a prototype for a protocol converter of Multicast/I2C on a Motorola HC12.

1/2001 – 7/2004

Developed spreadsheet gateway which basically is a mechanism for providing one or several Java-clients/GUI access to underlying data in a spreadsheet residing on a remote machine, thus enabling remote viewing of another trader’s spreadsheet. The spreadsheet engine was developed in-house: C/C++/Unix/TCP/IP.

Developed and extended functionality to performance monitoring and fault-checking tool in order to monitor availability of trade-servers/price-servers/order-outers etc.: GUI work/Java/XML/JUnit/Jemmy.

Introduced use of multicast protocol for all of our server-feeds using TIBCO’s API. Making it possible to run servers efficiently from a safe remote location: C++/Java, Unix/NT, TIBCO.

Developed simulation trading-strategies used by testers to test the trading applications providing trading primitives (order-traffic) for testing trading environment: C++ and Java (Swing), Unix/NT.

Added performance monitoring functionality to our new trading screen application, timing of data throughput, identifying slow links and changes in bottlenecks after redesigns: Java-coding/XML

4/1994 – 4/1997

Worked with flight software for the central data management system (CDMU) used for handling/routing of telemetry and telecommands onboard satellites (2 missions: Meteosat and Sirus II). Was part in designing a preemptive real-time OS in Ada. Also wrote embedded application software for controlling onboard scientific instrumentation and communication hardware. Worked as objectleader and designer.

5/1992 – 4/1994

Involved in designing/implementing a Unix-based distributed control system for maintaining and supervising a fabric of high-speed (SDH) cross-communication switches (SDXC). This work included TCP/IP communication and extensive Unix IPC (inter process comm.) between several software components, which collected alarm and control-information from the switches. My work also included firmware development used for transmitting data from the high-speed communication (2.155Mb/s) boards where the actual cross-connection switching occurred.

1/1990 – 5/1992

Developed a ground support system from scratch used in 3 different NASA “missions”. This system consisted of a scientific instrument (mass spectrometer) interfaced via a VME-bus to an embedded
5(5)

system running the Vrtx real-time OS and an application. The embedded application then communicated via TCP/IP to a UNIX host which visualized the data in a GUI (X11/Motif). The application running on the UNIX host ran a number of processes used to monitor the data from the instrument (to avoid overheating etc) and also to send commands and synchronize the telemetry from the instrument. After calibration of the instrument, in the lab, the instrument was put in a satellite and the VME-bus was substituted for a spacecraft onboard-bus, which then was controlled by the same UNIX host-application from ground when the satellite was launched.
