** built a distributed IT structure of the enterprise, working through unreliable weak communication channels. The system works until now in the enterprises of the region; ** implemented “from scratch” backup systems and automatic “rollout” of application software updates, taking into account specific features and requirements for reliability and stability in operation in a short time. There are a number of other abilities, although I am not used to bragging. ))

First of all, I am interested in working remotely or moving to your city (with the assistance of the company in search and rent accommodation, for example, for 1-2 months after relocate). Always ready for a technical interview (if necessary). Also important: ++ Adequate management. ++ Informal atmosphere. ++ Professional development and career growth. ++ Time and opportunity to learn new technologies. I would not like to spend time if: -- there are “pitfalls” when applying for work: including many interview stages, a trial period (probation period with a lower salary) and/or a test task longer than 1-2 hours of time to complete. I hope for a long and mutually beneficial cooperation! ))

Предпредпоследнее рабочее место: - Первым в СНГ выстроил ферму конвертации видео на бытовых видеокартах. Это сэкономило компании десятки тысяч долларов в год без заметных капитальных затрат. - Разработал оригинальную конструкцию CDN-серверов, которая позволила снизить требования к стоимости и количеству собственных CDN-серверов и в разы сократить расходы на собственный CDN. Предпоследнее рабочее место: - Увеличил пропускную способность системы более чем в три раза без роста серверного парка. - Расследовал сложный кейс пиковых нагрузок, порождавший лавинные эффекты в системе и частые даунтаймы. - Добился высокой доступности сервиса. Последнее рабочее место: - Возглавил и довёл до конца разработку аналога obfs4proxy для нужд продуктов компании - Реализовал cuckoo-filter в Redis - Сократил число серверов БД в три раза - Возглавил и завершил разработку нескольких новых типов услуг, предоставляемых компанией. - Разрешил закоренелые проблемы инфраструктуры: сократил в несколько десятков раз средний даунтайм сервиса в год; значительно сократил затраты на содержание ядра сети; организовал высокую доступность для веб-кластера и т.д. - Реализовал прослойку совместимости для бесшовной миграции с хранилища RIAK. - Реализовал умный L3-L7 маршрутизатор для нужд VPN-сервиса. - Реализовал для нужд VPN-сервиса оригинальное решение для port-knocking-а, основанное на PSK-криптографии вместо знания номеров портов. - Спроектировал несколько вариантов синхронизации документов KS Office. Некоторые из них пригодны для использования со сквозным шифрованием (то есть с нулевым знанием сервера о содержимом документа). - Обнаружил и исправил некоторые существенные проблемы в информационной безопасности.
