Experienced developer mainly focusing on (embedded) Linux systems.
Mainly focusing on system programming, communication and inter-process communication
together with Linux distributions and security.
Deep knowledge of various c++ standards and meta programming together with build system for cross compiling with various compilers. Modeling is usually done using UML.

Several years of experience regarding Continuous Integration, and using different types
of Unit test framework i.e GTest,GMock.

Requirement management, functional-/system testing is also part of resumé.

Always on top of the new technology and is a frequent contributor to the open source
community. Part of the spare time is dedicated to developing open source for Emacs,c++ libs,raspberry pi and other interesting projects.

As a person I'm socially-oriented and positive; easy to make contact with other peers.
Pragmatic and works both independent and in teams. Is very innovative, and always tries
to make repetitive work automatic. A lot of my spare time goes to reading new technologies
and inventions and try figure out new ways of implementing them.
Together with my Triathlon training I have 2 kids and a wife which takes up rest of my awake time.

Cocode open source libraries.
Github projects.
Contributer to babelc.

Previous Assignments

2016-2019 Volvo Trucks (GTT) Software developer

⋄ Software developer of embedded systems for telematic gateway.
⋄ Yocto development to create custom Linux distribution.
⋄ Part Architecture team for setting up development environment.
⋄ Using c++17

2016-2017 Saab Surveillance Software Developer
⋄ Software development on radar simulation software
⋄ The software simulates radar signals which are then sent to the radar software for
evaluation .eg targets, clutter, jammers etc.
⋄ The system runs on Linux system and is programmed using c++14,
it’s a high performance real-time software, where timing and optimization is highly valuable
⋄ Using methodology scrum ( jira )
⋄ Big part of the optimization of the software, where c++14 knowledge has come to usage.
⋄ Started transition for some projects to go from clearcase → Git
⋄ Update project to start working with CMake


2010-2016 Volvo Trucks (GTT) Software Developer
⋄ Software development of embedded systems for telematic gateway on trucks
⋄ The embedded system handles all communication from the truck to back office and other
nodes in the truck such as ECU's and IC's using 3G,TCP/IP,CAN,IR.
⋄ Main area was based on communicating with different peripherals connected to the truck
such as tachograph and other ECU’s, also developed and designed many of the
business logic such as Ehorizon, Driver time management, Driver eco coaching and more.
⋄ The system run on both Windows CE and OSE. Programming is done in (c++) Rhapsody which is a Visual development environment using UML, using Agile development
methodology (Jira, Scrum with Jenkins as build environment) . Test tools are developed in Java and Python.

2008-2010 Thoreb Software Developer
⋄ Software development of embedded systems for public transport equipments and vehicles.
⋄ The embedded systems handle communications with adjacent systems on the vehicle (e.g.,
CAN, GPS, sign control) as well as communication with the outside world such as via radio or any other communication channel.
⋄ Focusing on communication from an embedded system to peripherals, such as redlight-priority for emergency vehicles and public transportation.
⋄ Communication to driver via IC, i.e time scheduling.
⋄ These systems are exclusively run on Linux and programming is done in primarily in C++/C and Bash.

2006-2008 Autnonomica/Netnod Software Developer
