Combined responsibility: National Team coach for Juniors U21, and Judo Coach of Mäkelänrinne High School Helsinki.Really intensive and rewarding time to take coaching to the next level with 15 -17 members in a Junior National team. Preparing National Team members for 4 individual and two team European Championships. Two time preparing team for Junior World Championships for individuals. Coaching Juniors is preparing them for future career and I was happy to work with such a motivated team of Juniors!In Mäkelänrinne high-school there were 20 students in a judo group. The group was in different phases of their judo careers but goal was to encourage to everybody stretch and find out their potential within the sport. Support from the school and all the supporting activities were great and this environment enabled me to grow as a coach. Coaching included many disciplines besides coaching: Building team, planning, budgeting and arranging trips for the whole team around Europe and Japan. Approximately 12 trips abroad per year and 70 days of traveling for competitions and training camps.This was a fixed-term contract.

Antenna chief in metal flagship device antenna concept part. Responsible for supporting all antennas for full metal phone concept. Managing antenna concepting team of up-to 5 antenna designer contribution into the projet. Goal was to deliver antennas to match product program targets in size-and performance target wise. This has been really rewarding time for me professionally. From this role I got Exceptional performance-rating on review feedback during 2014- 2015. Really exciting period!

This is most busy and most exciting time definitely. We made with a relatively small teams and with really tight schedules really nice products. When starting I was HW project manager on BT-headset BH-904. We really worked hard to get it out as we wanted. After that I was involved in several HSPA product programs we were able to make and deliver. This have been the best time for me professionally to see how ideas from paper starts to come true and going for production. Best time to learn on co-operation, team work and whole process of making products. Along this time I really started to see how mobile data starts to come everywhere. Also magic on code domain data running on top of physical signals made big impression for me to think possibilities on HSPA and beyond.

This time I was developing modular testing methods for EMC testing. Motivation was to be able to pick up design failures in early stages of development without expensive laboratory investments. Main contributions were for spurious emissions, and radiated emissions. We made really nice achievements on product level EMC analysis work around this time. I was instructor for one Master's Thesis work during this time.Work was on radiated emissions from chargers.

Working on Signal Integrity and near-field emission topics. We did pretty succesful work around near-field phenomena on various parts on phones.During this time mechanics on phones were pretty complex and work around connectors, and cables and various FPC technologies were important for optimising impedance matching and minimise cross-talks, and intereference, or jamming for surrounding signals.Durign this time we were pretty successfully combining numerical simulaiton methods, and near field measurements and near field calculations for optimised design , minimising cross-talk, and optimise grounding and other critical topics.

As continuating from my Master's Thesis work I originally continued to develop our our 3D-FDTD electromagnetic simulation tool development. We were continuing to develope simulationg engine and paralaller I got some superiour support from my colleaque to develope 3D graphics support for our simulation machine to visualize 3D electromagnetic fields. This activity became obsolete when commercial simulation tools became so much better and we started to get our results faster using them. So for me this left as a great journey on programming with C, and C++ with a good idea how to organise a object oriented structure for program.During this time we started some near-field measurement activities for measuring components emissions for surrounding electronics. Also we made pretty findings and corrections for good EMI design principles.

I made my Master's Thesis work on FDTD technique improvements. These techniques were helping for calculating electromagnetics problems either faster or with smaller memory or with better accuracy.

I got wonderful chance to start as a trainee in Nokia Research Center. I joined for part of Aplac-team which was on that time still within Nokia Research Center. During my summer-job I got so interested on numerical electromagnetic modelling that I was shifting my major from RF engineering into electromagnetics. It took one year for additional studies but it really was worth doing.
