Name: Kim Olsen
Occupation: IT systems / operations consult and programmer
I am a 34 year-old full-stack programmer / developer and IT consultant with experience on multiple system-architectures / types in different operation-settings. I mainly focus on Linux and Unix-type (POSIX) systems on
x86 / x86_64 and various ARM-platforms.
I also have varied experience(s) with select PowerPC-platforms
(like Power Mac G5
(PowerPC 970FX) with OS X) and some
Sparc-platforms (SPARC64 / UltraSPARC)
running Sun Solaris
(I have experience with this OS on both the SPARC- and x86/x64-platforms).
I would describe myself as independant, structured, problem-solving and responsible. I like challenges and am not afraid to give an extra effort. I also possess quite a bit of special competancy in; admin / security / network, but I also learn quickly about new technology.
I have american blood on my mother-side of the family, so I both talk and write fluent english.
Earlier positions have included responsibilities and work-tasks that includes: system-administation, network-security, server-patching / -problem-solving, rack/blade-operation and other complicated (and less complicated) assignments in datacenter- / «corporate»- and small / medium-sized private businesses.
In Linux-based technology I have used different distributions over the years (even on differencing platforms), but always ended up using (and loving) the 3 originals; Slackware, Debian and Red Hat.
I personally use desktop-Linux for daily routines / tasks, have favored the use of Linux for server-tasks / stability, use my own customized Linux-based solutions on integrated systems (embedded / SoC) for diverse purposes (weather, surveillance, digital remote-lock) and I've configured and operated standard-services (e-mail / webservers / routing / SQL / NoSQL) and more advanced services (OpenStreetMap / PostgreSQL / PostGIS / enterprise-firewalls).
On these forementioned platforms and systems, I have (among other things) most experience with the following solution-stacks
LAMP (+ other AMP-stacks) and
Among catalog-services I have experience setting up and operating SMB/CIFS+OpenLDAP (cross-platform AD-compatibility) and standard *nix-specific LDAP+NFS-structure(s).
I also have normal > advanced experience with more conventional types of operating systems, data-ecosystems and setups
Wintel / Active Directory) / Cisco Catalyst / HP ProCurve and other brands / types of OSI (Level 2+3) enterprise-/datacenter-level networking equipment.
I did consulting work on programming and utilizing
for use within an open source "geolocation"
framework, while at the same time maintaining / operating and securing the rack-infrastructure (domain, network,
web-servers, databases, maptile-servers, geolookup, reverse-geolookup, coordinate-search, and so on)
that comprises the backend(s) for the whole framework.
I've dipped my hands in a plethora of computing-environments and usecases, you could basically call me a computing
I've also programmed quite a bit in a heap of different languages, like:
I am going to attend a precourse for engineering studies (Mathematics 1R + Physics 1) in fall of 2017. And I've been out looking for, and finding, some part-time work / contract(s) as a result.
Got any questions? Or maybe an opportunity waiting?
