Education & Work Experience

I was born in Istanbul in 1975, after having completed my primary and secondary education in Istanbul I graduated in 1992 from Science High School of Bursa. In 1992 I attended to the department of Istanbul Technical University - Electronics and Communications Engineering.

I performed the database management at European Conference of Circuit Theory and Project (ECCTD'95) which has been organized in Istanbul in 1995 while I was studying at university. In the same years I have supplied Data Processing consultancy services in many private sector companies. After the end of the conference towards the end of 1995 I worked in the IT department of FMV Işık High School. My responsibilities included to enhance the local network, to spread the usage of the Internet and training of the users.

I participated to the MagNet project at the end of 1995. MagNet was one of the first ISP companies in Turkey, however was closed down in 1999. I performed twice the Turkey Internet Users’ Survey in order to determine the profile of Turkey’s Internet users at MagNet. The results of this research have been used by many media institutions and Microsoft as a reference. After having worked as Technical Manager for approximately two years I left MagNet and worked for a system integrator again as Technical Manager between 1998 and October 2000. Here my responsibilities were supporting the presales, after sales and marketing departments, management of the technical team, follow up of installations and obtaining the licenses for the imported telecommunications equipments. Besides, I also arranged for the sales and technical trainings.

1. Every thing exists in the universe has at least one purpose.
