Roger Madsen's Summary

I'm a passionate and dedicated senior software architect/developer. Quality and end user experience is of highest importance to me when I develop software. I enjoy the visual aspects of creating software applications as well as what goes on behind it. I put high value on architecture design and writing good code but even more important is getting things done.

I have been working full time with Android development since it was released (5+ years full time Android experience). I have very good knowledge about every aspect of Android application development and Android architecture.

I have 10+ years experience in telecom.

* Software consultant at Ericsson working on a billing gateway for mobile networks.
* Software consultant / staff engineer at Sony Ericsson working on the telecom software inSony Ericsson phones.
* 5 years as lead architect for the telecom software in Android on Sony Ericsson / Sony Mobile phones.
* 3 years as expat in Beijing, China as a lead architect for telecom on Android.

I switched track recently and I'm now building my competence to develop cloud software for Sony products.

I have created Train Info Sweden. It's one of the most popular Android app for train commuters in Sweden. It is currently rated 4.3 in Google Play with 61 votes.

Roger Madsen's Experience

Senior Software Architect

Sony Mobile Communications

Privately Held; 5001-10,000 employees; Telecommunications industry

January 2004Present (10 years 9 months) Beijing City, China

I started as a consultant and then 1 year later I was employed.

My expertise at Sony Mobile is telephony and Android. Telephony includes phone calls, mobile networks, data communication and SIM handling. I was picked to be part of the initially small team that was setup to work with Android when Android was released. I was assigned as architect for telephony on Android and have had that role since.

In early 2011 the telephony area was moved to Beijing and I continued my role as telephony architect in Beijing on expat. Working abroad has been a really interesting experience and it has teached me a lot about working (and living) in a very different culture. One challenge for me in Beijing was to also work with building the competence of the team I worked in which was fun and a learning experience.

Before Android I also worked with telephony but then in a embedded system for feature phones and C++ development.

Software developer consultant working with the development of a billing gateway for mobile networks. Different mobile networks provide billing data in different formats and to allow different networks to share billing data (if you are roaming for example) then it goes through a billing gateway. It's comparable to Microsoft BizTalk server but more specifically for mobile network.

I developed both in C/C++ and Java during my assignment here.
