This toolchain allows analysis team to write highly customizable performant code to analyze and detect malicious application behaviour.* Developed rootkit detection module to find and remove rootkits that had already crept in the system before antivirus installation. Reverse engineered Windows kernel structures to find and neutralize rogue hooks, overriding system access permissions. Removal module rebuilds critical OS data in the runtime to ensure integrity of the system.* Disassembled and analyzed virus samples to develop new detection techniques.* Improved and extended custom DSL for AV signature matching.* Profiled and optimized signature matching algorithms.* Developed module to detect code injection into a running processes.

* Developed distributed web crawler Msnbot 2.0 to visit web sites and download billions of documents per day for Bing search engine.* Designed the system to be reliable and failsafe, to work with minimal devops intervention; to automatically detect and retry failed jobs while trying to obey web-site's robots.txt rules.* Developed tools to simplify debugging, profiling, and log aggregation across hundreds of machines in the environment.

Saint Petersburg, Russian Federation

* Developed and integrated Direct3D graphics backend for fast chart manipulation in vessel navigation and port management software.* Improved and extended cartography visualization engine: developed new widgets, implemented data serialization, etc.* Developed tools to fetch and convert weather data, and draw it over naval chart collection.
