I was born in 1973 and have an MSc degree in Physics specializing in methods of mathematical physics.

I joined Tydex in 1997, following post-graduate study at the Faculty of Physics of St. Petersburg State University. The company was growing fast and we were active in almost all fields of optical business. That gave me the opportunity to experience the widest range of optical components and materials, from UV to THz, from just protective windows to precise laser active elements. Due to a shortage of specialist staff, each of us had to provide complete support to his projects, starting from discussion of technical details with the customer, through to buying raw materials and supervising the manufacturing process to final QC, customs clearance, billing and collecting payments. Thanks to this, I know the complete business process in Tydex ab ovo usque ad mala.

As the company evolved we began to run our own production workshop, QC department, logistics department and commercial unit. During this expansion, we dropped some activities to focus on the fields where we are strongest and most competitive. Sales engineers in the commercial unit share these fields such a way that the customer gets the feedback to his request from the most qualified person in the field of his interests.

At present I am senior sales engineer and "my" product is coatings. I am also responsible for supervising the development of new challenging technical issues in the company. For example, I headed the establishment of the thin film department  and spectroscopy measurements department, the modernization of our interferometers and participated in elaborating the Golay cell calibration procedures. I am also supervising the evolution and support of our corporate network.

During my work at Tydex I have represented the company at over a dozen Russian and international conferences and trade fairs. My English is fluent.

In my spare time I enjoy field archaeology.
