Work Experience

2008, August - present, Survey Sampling International — Hungary, USA, Japan

Survey Sampling International (SSI) is a survey taker supplier of market research companies. He was hired in Hungary by a software supplier of SSI called Nebu. He has become a part of SSI when the development team was acquired by SSI in 2012. Please find two example initiatives below that he was contributing to.

Integrated Partnership

In 2012, he started to work on a program that could contact survey takers without having to have their email addresses. He took part in the negotiations with the third parties. The initiative has become a success and is growing steadily.

Scalability initiative

The scalability initiative aims cost reduction and providing headroom for business growth. Proven accountability guarantees him the freedom of choice in tools and methods many of which is carried into other developer teams as best practices. His team re-architected several critical software components making them extensible for future needs and also hundreds of times less resource intensive at the same time in comparison to their predecessors.

January 2008, Microsoft — Denmark

He has been offered a Software Engineer position at Microsoft Development Center of Copenhagen. He declined the offer in favor of a Ph.D. program.

February 2006 – January 2007, Positron Emission Tomography Center of Debrecen — Hungary

He spent a year of internship at the Positron Emission Tomography Center of Debrecen working with C++.

The first 6 months was dedicated to improving the user interface of medical scanners using QT4.

The second 6 months was spent on statistical image reconstruction algorithms related to the Ph.D program he enrolled in 2006. After the internship was over he got a full time offer which he declined in favor of the Ph.D program.
