This introduction (till Dec 2009) per wordle.

I am a director of engineering at EBay since December 2009. I am managing a talented team of engineers developing innovative buyer experiences in various verticals.

Before EBay, I was a director at Yahoo Web Search between January 2006 and December 2009, managing a talented team of engineers. Our focus was white-box metrics-based analysis of web search systems (crawlers, web graphs, indexers, search and proxy tiers, etc), web search data (discovered and crawled content, hierarchical web graphs, indexed content, system logs, user click / view / visit logs, etc) and the trends on the web (static vs dynamic content trends, sitemaps / robots.txt usage, user tags, etc). We ended up using techniques from distributed systems on the grid (via Hadoop and PIG), data mining, machine learning, web search technology, performance analysis, metrics, statistics, and more.

Before Yahoo, I worked on the electronic design automation software, i.e., semiconductor chip design software, at Synopsys for 6.5 years. Before Synopsys, I was a doctoral student at the University of Illinois at Urbana-Champaign but I spent the last 3 years of my graduate student life at the University of California, Irvine as a visiting scholar. Before California and Illinois, I was living in Turkey. I went to Bogazici University in Istanbul for my undergraduate degree and to Bilkent University in Ankara for my MS degree.

At Synopsys, I led the Variation-aware PrimeTime (PrimeTime VX) product from its conception to its first-time beta release. PrimeTime is the market leading timing sign-off tool for chips, and VX is the version that performs statistical timing analysis.

At Synopsys, I was also a team member of two first-time software product developments and releases (for SystemC library and SystemC compiler). Moreover, I was a team member of one ASIC chip design from its conception to its tape-out.

You can think of this home page as the html version of my resume (also see its PDF version). I intend to use it to share my research work. Please use my email on the left bottom of this page if you are interested in any of my publications.
