HP Software, Data Science Engineer (2012 - current, cross-product part-time activity)
HP Software Innovation Council, CTO Office, ADM.
Single-handedly developed a machine learning-based event classification tool for HP Arcsight's in-house security vulnerability categorization system. The tool receives free-text event descriptions from a large number of security and network appliances (firewalls, routers, etc.), crawls the internet for additional data about each event, performs a number of text processing and statistical operations, and in the end automatically classifies all events using a variant of decision tree algorithm. The tool automates thousands hours of manual work by HP Arcsight's 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.
