Developed a machine learning-based event classification tool for HP ArcSight's in-house security vulnerability categorization system.
The tool classifies events coming from security and network devices, based on data learned from the devices' documentation and internet sources, into one of many categories used in-house by ArcSight.
The tool automates thousands hours of manual work by security experts.
I was guided by HP data science team and Arcsight's security experts to first develop a proof of concept algorithm and then turn it into a real in-house tool with distributed infrastructure, retraining and multi-user support.

Developed the first link aggregator in Russian blogosphere - a website displaying "top 10" lists of most popular content in the Russian section of livejournal.com.
Content popularity was measured by a number of links from other blogs, and the website provided daily, weekly and monthly aggregations of most referenced entries.
The system contained a crawler that constantly scanned ~100K blogs for new content and extracted embedded links, hourly calculation jobs that performed aggregations, and a website displaying the results to end users.
I developed the service in my off-work hours for two months before it went live, and then spent about a year maintaining, adding new features, fighting spammers, and generally learning how to run stuff on the Internet.
It was a very happy and educational experience.
