Alexey Anisimov is a seasoned Unix system administrator with 13 years of experience building and maintaining high-availability infrastructure across telecom and consulting environments. He has deep hands-on expertise with virtualization (Xen, VMware), SAN storage, DRBD/OCFS2/HeartBeat, and backup systems like Bacula, combined with database and mail system tuning (Oracle, MySQL, Postfix). Alexey has a strong operational security mindset, having developed enterprise server protection schemes and written numerous custom scripts, modules and daemons to automate and harden services. His background includes performance optimization of billing and caching systems (SNMP, NetFlow, Squid+WCCP) and migrating telephony platforms to Solaris, reflecting both systems engineering and platform migration experience. Currently at AT Consulting, he continues to apply pragmatic architecture and automation skills learned from roles at Corbina Telecom, Vimpelcom and Oversun Scalaxy. Colleagues would note not-obvious strengths: he blends low-level systems programming with large-scale operational practice, making him comfortable both scripting and designing resilient production architectures.
