I am an experienced software engineer, researcher, and technical communicator. My objective is to work on advanced R&D projects.

 I research, design and prototype new ideas in data management systems.

o    Ph.D. thesis research on Web-databases and Real-time databases (admission control, CPU scheduling, concurrency control to balance Quality of Service and Quality of Data).

o     Research on data mining, in particular, graph based link analysis and anomaly detection.

I have in-depth knowledge and extensive development experiences with databases.

o    4 years Java development experience of a prototype system to simulate a full-fledged in-memory web-database.

o    Experience of processing millions of NYSE and NASDAQ Trades and Quotes data sets using Python and Perl.

o    3 years application development experience on database systems: Sybase, Microsoft SQL server, and Oracle.

o    2 years kernel development experience using C++ on OpenBASE Mini (a mobile database system deployed on palm OS or windows CE).

o    Experience with data analysis using Matlab.
