High-level experience

On a high level I have experience with the following (not listed in any particular order):

• Unix, OS/2, Win16, Win32 and DOS programming
• Server management
• Database management
• Network management (LAN og WAN), incl. WiFi and Zigbee
• 3GPP IMS (the charging og policy part)
• Partner support
• EDI
• Print management to a lesser extent
• Used to travelling - I have been sent to customers and partners in Australia, Austria, Germany, Italy, Poland, Ireland, Spain, Tunesia and the USA.

Low-level experience

• Programming in C, C++, shell-scripts, Python, Oracle PL/SQL, Progress 4GL, Pascal, Rexx, assembler, lua
• Linux, Solaris, HP-UX, AIX, a bit of Ultrix (only management) and a bit of Windows NT
• RADIUS, Diameter (Gx/Gy/Ro/Sy), LDAP
• EDIFACT and specialised formats, tracing & tracking
• Oracle 8/9/10/11
• Mysql/Mariadb/OpenTSDB
• Progress v7 og v8
• Micellaneous:
  • Squid (including transparent webproxy)
  • Apache
  • Name server (DNS)
  • MIME
  • Various socket programmering under Unix, win16, win32 and OS/2
  • 'native' win16, win32 and OS/2 programmering
  • SMP/multithreading (including on Sun T1..T4 coolthread servers)
• IP, routing, firewalls
• Sun/ONC RPC
• Producing technical documentation
• Benchmarking / performance-analysis
• CVS, Subversion, Mercurial and Git
• Knowledge of HP Serviceguard (and rudimentary knowledge of Sun Cluster)
• Policy and charging with Sandvine, Ipoque, Procera, Allot and Cisco
• Zigbee, Modbus, RS-485, DNP3

Other things worth mentioning: I can read, understand and implement according to IBM documentation, RFCs, ITU-standards, 3GPP-, WiMAX- and EDIFACT specifications; I can find difficult-to-find bugs; and I work from analysis to bit-twiddling.

Special interests

There are some areas that particularly interest me:

• Distributed computing
• Multithreading
• Scalable systems
• Networking

Education/Courses

• EDB-assistent ("Programmer's assistant")
• 2 "datanom" courses
• "Datamatiker" (with a score of "outstanding" in algorithm construction)
• Inside Oracle RDBMS
• UML+patterns
• IPv6
• HP ServiceGuard

Employments

• 2014- : independent contractor
  • Smart Grid Billing / Gridrabbit: building automation and energy management specializing in hotels
  • Privacore: Privacy and independent search engine
• 1999-2014: developer at CSGI International (who bought Volubill (formerly Intec Telecom Systems, Denmark (formerly Digiquant (formerly Belle Systems))))
• 1996-1999: programmer, but also "all outstanding work" (FAÅ/ÅSK/CSA)

Articles / Speeches

I have also written a few technical articles:

• SMP - Symmetrical Multiprocessing
• Hunting Memory Bugs
• I gave a speech about Flexelint at the Danish debugging conference in 2013. video, slides

Languages

• Danish (native)
• English (business level)
• German (not adequate for contract negotiations though)
• Italian (I'm still learning)
• Norwegian and Swedish (some; due to the Scandinavian dialect continuum)

Personality/interests

I'm 51 years old. I like cats, coffee and science-fiction.

Hobbies

I also tinker with stuff in my spare time, which may give some insight into what I can do:

• I have implemented a NNTP server (usenet news) which ran under various Unixes, OS/2 and win32
• I implemented a cluster mangement system for Unix
• A debug-heap which was a great help (before valgrind matured)
• I ported hoard to HP-UX/PA-RISC
• I made a multi-threading analyzer which can find potential deadlocks. Some of the ideas may have made it into helgrind
• A C++ library for processing flat files with support of relational algebra
• A miniature HTTP server
• My webserver runs on a Alpha-machine PowerPC-machine LXC container
• I have been running IPv6 on my internal network since ~2004
• I have implemented fail-over, shaping and fair-use of my internet connections
• I sometimes work on the SCTP implementation on linux
• I have implemented an X/Window server for win32
• I try to learn Italian
• I have implmented a diameter stack in Java and Python (at CSG I did one in C++)

My future position

I imagine something like this:

• The backend, meaning server-management, networking or similar
• "Core technology" / new technology
• Design/analysis/programming
• Some customer contact
• In a team of at least 5
