I've obtained the bulk of my work experience in R&D of Sonera and later Teliasonera corporations. During my trainee period, I became familiar with the functionality of different IP-network elements, especially in relation to performance testing. My competence later expanded towards mobile networks, where I initially designed and implemented a system to measure performance of the gateway node between mobile core and other networks. During the post-graduation career, I've participated in numerous and varied projects, of which the most important ones have been

• Working as an expert in Intelligent GGSN project. The objective was, after Teliasonera-merging, to homogenize the diverse vendor base in various mobile network cores around the Nordic countries to achieve synergy benefits. My role included evaluating several different vendors both on paper and in practical lab experiments and giving recommendation on the best choice from technical perspective.
• Several IPv6-related projects, where the goals were to eventually start up IPv6 technology offerings from Teliasonera.
• Acting as a security specialist in several TEKES (Technology advancement center of Finland)-funded projects. After long experimenting and development period with various security-related tools, one of the highlights include a company wide documentation on how to validate the robustness of any new technologies, software and hardware, from security perspective.
• Standardization work in IETF organization and collaboration with Finnish research organizations as part of TEKES-funded Mercone, WiseCiti and FI ICT SHOK projects. Primary standardization topic was enabling virtual operators by utilizing Mobile IP. Other topics have included vertical handover handling between various network technologies and initial introduction of P2PSIP towards corporate deployments.
• Participation in next generation managed corporate network project, which covers managing customer network users across various network access technologies and the security of their workstations and other terminals.
