 Positions Held:

  • 2007–now: Associate Professor, tech leader at “ITMO University” (Saint-Petersburg). Gave lectures or managed lab work of students in the following courses: “Informatics”,“Parallel computing”, “Discrete event modeling and simulation”, “Telecommunicationsand Computer Networks”. Carried out scientific research both as a programmer and a technical leader (projectmanager) for projects aimed at creating the following simulation models: a WiMAXnetwork, an automated car parking system (GPSS language), a routed computer networkwith QoS diffserv policies implementation (NS-3 framework in C++ with Qt GUI), a queuing (e.g. WFQ) network module (Anylogic). Wrote training aids (books) for the following courses: “Wireless Networks”, “Modeling (simulation)” and “Parallel computing”. Supervised approx. 30 B.Sc. and M.Sc. students on their way to diploma.
  • 2017–now: research engineer at “Huawei” (SPb). Performed research of bandwidth sharing algorithms. Performed research of compression algorithms (zstd compressor, FSE). Software used: git, SVN, Eclipse CDT, make, gdb, Google Performance Tools, gcov, Valgrind, Wireshark, VirtuaBox.
  • 2015–2017: senior C programmer and project manager at “NRI Mashtab, Ltd” (SPb). Performed research of multi-home L4 protocols (MPTCP, SCTP). Created a prototype of a DCCP-based multi-home tunneling network applicaton. Wrote an application to measure network route capacity and interfaces load per-application and per-TOS.  Supervised a team of 6 developers in a software firewall/router project. Configured Redmine for the project. Planned tasks for the team to meet long-term requirements using MS Project. Discussed FSTEK (ФСТЭК) firewall requirements with customers to reduce project risks and shrink timeline. Monitored team activity, fixed problems.
  • 2012–2015: senior C programmer at “Evelopers, Ltd” (Saint-Petersburg). Ported existing Linux code to Mac OS X. Maintained and developed cross-platformcode base (Linux 32/64, Windows 32/64, Mac OS X). Ported Visual Studio 6.0projects to Visual Studio 2012. Team tools: Jira, Confluence, Crucible, FishEye. Implemented converter of sFlow and Packeteer network traffic into NetFlow v.9. Maintained and developed a scalable multi-threaded cross-platform high-load
  • network-oriented distributed application for processing of mixed traffic: Packeteer, sFlow, Netflow v5/9, IPFIX (including use of raw sockets API). Maintained and developed various SIEM features: analysis of Cisco ASA logging, botnet detection, traffic anomalies analysis using statistical methods, DDoS detection mechanisms, network health assessment using VMWare VCenter IPFIX flow records for VXLAN-residing virtual machines (including manual VCenter configuration),  SNMP manager development, event notification using Syslog.
  • 2004–2007: C programmer, QA Engineer at “Sunrise-R SPb”, Ltd (Saint-Petersburg). Modified firmware of a GPS tracking device to implement power-saving mode. Modified Linux network drivers to implement jitter buffer for an RTP stream. Implemented a partial decoder of MPEG2/4 network streams. Implemented a parser of log files from a GPS tracking device. Performed usual QA-related tasks: finding bugs, reporting them in a bug-tracker (IBM Lotus Notes, Redmine), verifying fixed bugs, designing test cases.
  • 2003–2006: system administrator at “Reyder”, Ltd (Saint-Petersburg). Maintained small office LAN (software/hardware upgrades, user management, backup activities, antiviral protection). Administered databases (MS Access, 1C). Maintained internet proxy-server (Internet sharing, firewalling, setting quotas for users), file server (access policies), mail server (SMTP and POP3 protocols).
