I'm a medical software consultant doing architecture and development of secure healthcare applications. If you need an up to date CV, please contact me by email.

Chronology

• 1951: born in Stockholm, Sweden.
• 1969-71: University of Stockholm. Mathematics and anorganic chemistry. ALGOL programming.
• 1971-78: Medical school, University of Ghent, Belgium. Graduated with honors degree.
• 1978-83: Surgical residency under Prof. Derom, University of Ghent.
• 1979-82: (overlapping) Student electronic engineering, University of Ghent. Did not quite achieve a bachelors degree.
• 1983-94: Part time GP practice, software development and hardware sales (see below), my own company.
• 1995 and onwards: nothing but software development (see below).
• 2001: moved back to Sweden. Still nothing but software development.
• 2002 january: authorized to practice medicine in Sweden.
• 2004 december: Certified Information Systems Security Professional
• 2005 may: Certified Software Development Professional

Languages

• Fluent in Swedish, Dutch, C++ and English. Working on my Polish ("oh, jej... ojej!").

Medical and surgical experience

• During medical school I had the occasion to work extensively in clinical laboratories.
• My surgical residency included general, abdominal, thoracic, cardiovascular and orthopedic surgery. I was also extensively trained in intensive care and trauma surgery.
• 12 years of general practice in Belgium.
• Licensed as general physician in Sweden (EU).

Software experience

• Trained by Hewlett-Packard, Boston, in 1989 in using and programming the RTE-IV operating system and utilities, Fortran, Ratfor.
• Extensive experience with compiled basic and Z-80 assembler while building both database applications and industrial measurement and control systems 1983-86.
• Extensive experience with Clarion for Dos for database apps 1986-present. Had three technical articles published in Clarion Tech Journal (may it rest in peace).
• C: fairly extensive experience.
• 80x86 assembler: fairly extensive experience.
• C++: extensive experience.
• C#: beginning to intermediate.
• Pascal/Delphi: extensive experience.
• Some knowledge: Oracle-2000 design, Java.
• Bad experience: Centura.
• Installation and administration of Solaris and SunOS (enough for most daily tasks). I was (informally) the chief technical officer for MediBridge, responsible for the Unix systems, the Novell 4.1 installation and administration, the telecom setup and client software administration.
• Administration of HPUX and Reliant (Sinix). Cisco IOS and firewall configuration and maintenance. DNS and mailrouting administration.

Software written long ago

Note: later software products to be found under "Recent experiences".

• 1980: A non-invasive cardiac output calculator, using bidirectional doppler measurements of aortic arch diameter and blood flow. The flow curves were divided into one wave complex per beat and then allocated into up to 12 wave classes based on template matching. These were then separately integrated for flow and added. Fortran on HP 2100 under RTE-II.
• 1981: Simple medical procedure database for use on intensive care. Used my own string indexing routines accessing disks by track, sector and byte for performance. HP2100 under RTE-II, Fortran.
• 1981: Clinical study management package for printing questionnaires, entering results and doing interactive correlation analysis using t-test and chi-square on the resulting database. HP2100 under RTE-II and Fortran.
• 1983: A custom pre-compiler with screen tools for basic and termcap-like abilities for MPM-II terminals (everyone wrote one of these back then…)
• 1984: A multitasking data collection package, including graphics output and thermodynamic calculations. Running under CPM-80.
• 1985: Process control, central heating system in a mall in Belgium, using a Merlin Systems (UK) process computer with embedded special purpose basic. Also designed and built the amplifier circuits for the interfacing. A second similar installation in a technical school in Belgium.
• 1985: Utilities for pre=calculating dimensioning of central heating systems, including heat pumps.
• 1986: A package for calculations, including simulation, of airconditioning systems for office suites and computer rooms.
• 1988: Insurance broker package.
• 1990: Accounting package. Including a recursive-descent expression parser for template driven balance generation.
• 1990: a medical telecommunication system consisting of a server side application running on three workstations and a client side application. Both of these written in a mix of Clarion and assembler. The package assembly/disassembly routines, the handshaking protocol, file exchange protocol and the CRC routines I wrote in assembler (I didn’t invent the CRC routines, of course). The communication driver was a standard fossil-5 driver. This system ran for four years serving a small number of GP’s and labs in the western part of Belgium between 1991 and 1995 and was definitely one of the first such applications in Europe.
• I was also listowner (“DIABETES”) on Bitnet from 1989 or so, which can count as very early Internet experience. (Wasn't this before the Internet was the Internet? I have these flashbacks about the Arpa net and stuff.)
• Assistant sysop on Compuserve for a limited time around 1990, diabetes forum.

Hardware experience

• Care and feeding, including repairs, of HP 2100 and to lesser extent the HP1000 series of mini’s (late 1970’s).
• Fair experience of using and understanding logical analyzers for service and driver development.
• Designed and built interfaces for A/D systems to connect both pressure heads and Pt100 and NTC probes.
• Repair and modifications of any number of microcomputers during the 1980’s.
• Installation and maintenance of networks ranging from mmmOST, Network-OS (CBIS), InfoShare/M to Netware 2.0 to 4.x. Based on RS-422, ArcNet and Ethernet.
• 1992-94: custom assembled a number of stand-alone and network computer systems (“clones”).
• 1995-98: misc companies, took care of Novell systems on PC hardware, Sun Sparc 5 and Netserver, Siemens Unix ("Sinix") system, HP Unix workstation, and many types of Intelbased servers and workstations. Took care of Bay networks routers, bridges and switches for a large mixed LAN system.
