Software Development

I am a great Software development generalist with a heavy product and entrepreneurial experience and focus. I have some language preferences, but have used enough different languages that I learn new programming languages very quickly.

I have been doing both hands-on solo development, been part of a development teams, managed development teams (on-site and off-shore), and done architecture and project management (of large scale) software products. In my different endeavors through-out the years, software development has always been a component and something I keep active and alert with-in (either as main focus in a new startup, or through side projects).

Development productivity, well structured (maintainable code) is important to me. I know that developer productivity can vary by an order of magnitude between developers, and know what to look for when building development teams.

Orange Mobile Services Platform. Developed part of the platform in Java, later on created the architecture and assembled the development team for the Portal Server (Websphere), CMS (Interwoven and custom) part of the project. The project consisted of a team of aprox 100 members, with a budget of aprox EUR 50M.

VIOMA Media Manager. Created architecture and initial code base, and setup and managed development team to build a distributed Media Management (add-on) product on top of VIOMA Content Manager, that seamlessly interfaced (and replicated media) across large scale deployments of standard streaming servers. Primary target where VOD services for Cable networks and Teleco’s.

VIOMA Content Manager & Integration Server. Enterperise Content Management and Data integration platform. Founded the company around my product idea, and I created the architecture and developed the initial code base for the product line, including a XML database engine, data integration and transformation. Product was built in Java, built and recruited development, Q&A and documentation teams for scaling up product development.

Learning Management System. Designed and built the first Internet based LMS system deployed in Sweden in 1997. Built using various technologies (Java, C++ and Lotus Notes) and run distributed with (on and off line) with data replication between servers and clients.

Winix Groupware (1992). Was part of the development team that built a Internet based groupware solution in 1992, before graphical web-browsers. It consisted of a UNIX based back-end, and Windows based front-ends, and written in C++. Worked mainly on Terminal emulation and scripting language engine.
