Alexander Sibiryakov

I spent 5 years at Yandex as engineer in search quality department. Social search (dealing with the full Twitter feed), question-answer search and improving snippets. After that I spent 2 years in Avast! antivirus building automatic resolution of false positive submits. Currently I'm the core contributor of Frontera at Scrapinghub Ltd. My main interests are information retrieval and processing large volumes of data.
