I am a senior architect with a solid development experience in Enterprise
environments. I have more than 20 years of software development experience. The
last 12 years my focus has been on Java and JEE based frameworks and before that
I was the architect and designer of similar multi-layer application frameworks
written in C++. My extensive knowledge gives me a unique ability to quickly
grasp the complete picture. I master the whole range of technical solutions
found in large systems with complex integration scenarios, distributed
transactions and message queues.
My objectives are often to run the project all the way from the initial
requirements to a complete architecture and then to act as both mentor and
developer. I am used to lead the architectural work and to establish a common
vision in the team. I am not prestigious but can act convincingly when there is
a need for it. I am an appreciated teacher and can explain even the most
abstract problems in an understandable way.
I have learned to take advantage of the benefits gained by good architecture,
code reuse, documentation, and quality awareness. I posses the knowledge needed
to construct and sustain a development process that will live on in an
ever-changing environment. I am used to work with Component Management systems
and well acquainted with Rational Unified Process (RUP).
I was born in 1960 and raised in Skåne (southern part of Sweden). I moved to
Stockholm in 1987 and then stayed there except for 3 years in New York (01-03).
I am married to a girl from Hälsingland. Together, we have 3 wonderful boys.
Aside from my work and family I like to build my own home
computers and I am very fond of music. I exercise on a regular basis on the
