About me:

Several years ago I worked with free-falling gravimeter and developed aerospace lasers. My work was producing a source for Michelson interferometer — ultra-stable green laser besides installation all gravimeter systems. It was a very precise optical and mechanical work. Also, our team went to test sides to test the gravimeter. There I upgraded my hand-working skills.

Aerospace lasers very difficult, because you should make them on the Earth's surface, and they will work in space, there are no atmosphere and gravity. All those tasks need strength and heat calculations and very precise work. My Master's thesis was about the ability to build a satellite-based comb-generator. 

These works gave me engineering experience and passion for design new products.

Now I’m working in TET ESTEL AS. I’m developing thyristor converters and additional equipment interacting with electrical engineers, supply managers and production department.

Earlier I worked in Arlift International and my work was to develop new models of vacuum lifters and other lifting equipment. It was a full circle work, from customers' requests, to get their requirements, and design to serial production, maintenance, and drafting documents. I got there a great experience in product development.

I’m a good team player, but can work stand alone. I’m glad to meet and learn new things. Design work set unusual requests and need for knowledge in related fields, not only mechanics. I would love to leverage my multidisciplinary knowledge, development and managerial experience to do perfect work. I'm interested in complicated engineering challenges.
