CV

Leif Helge Indrevær

Development Engineer and System Architect

Introduction

I have been working in the embedded system world for around 40 years. My best field of expertise is HW design and low level programming for embedded MPUs/MCUs. In the past I have also done a lot of 3D modeling and mechanical construction of enclosures.

 

I was educated at the Norwegian University of Science and Technology (NTH/NTNU). After military service I then worked for 18 years in the analog mobile telephone industry before entering the fields of digital communication (ISDN). After this I was engaged as project manager for the development of a combined GSM/ICO handset for Nera Satcom.

 

In 2001 I joined Flextronics and was assigned a position as development manager. In 2007 I returned to basic electronics development as a system architect at Kitron. From 2016, I offer my services through my own consultant company Siv.ing Leif Helge Indrevær registered in the Norwegian Trade Register (www.brreg.no), organization no. 976499026.

 

I have acquired a large experience in electronics design and low level software development for embedded systems. I also have a broad experience in designing analog and digital electronic systems, schematic capture, pcb layout, simulation and integration. I am considered as a very efficient developer, putting my pride in delivering quality results on time. Every time.

 

I am certified by NSM (Norwegian Security Authority) to work with classified projects up to (and including) NATO Confidential (NC). I also hold a Crypto Qualification Certificate grade II.
