Free and open source QA tool for MySQL and its derivatives. Presented at HighLoad++ conference in 2016.

Worked on HADOOP clusters for http://market.yandex.ru.

One more project to work on. responsibility for all build infrastructure, releases, packaging and some other related things.

Jenkins and all related things. Virtualization, slaves, logic for Jenkins jobs, etc. a lot of various things.

Worked on packaging bugs, main projects: Percona Server, Percona XtraDB Cluster, Percona XtraBackup. Fixing, testing, fixing again, releasing, writing configuration for puppet from scratch, working on jenkins infrastructure. Results: understood the projects, fixed a lot of bugs properly, moved build nodes away from expensive EC2 to datacenter in BM.

At some point Schooner has been acquired by Sandisk Corporation. Responsibilities: - Supporting of infrastructure and products previously created for Schooner. - Redesign of production builds to move away all open source components from builds. Results: redesign successfully done. Means: OS: Centos (5,6) Software: shell, python, rpm, yum, hudson/jenkins, trac, svn, mercurial, cmake.

- Transforming source code into the products. - Design and support of build infrastructure. - Design and support of built RPMs and installer. - Design and support of internal yum repository. Results: - Created build systems based on Hudson/Jenkins. - Created internal yum repository for Centos. All software packed to the RPMs (products and build dependencies). - Written installer for products. - Done 2 major releases for SchoonerSQL and Schooner Membrain and several minor releases for each product. Means: OS: Centos (5,6) Software: shell, python, rpm, yum, hudson/jenkins, trac, svn, mercurial, cmake

- Working with the architect of the project and independently. - Designing and supporting failover architectures based on Gentoo and Debian/Ubuntu. - Supporting CI process and build automation for Linux (server part), Windows and MacOSX (client parts). - Statistics collecting and aggregation. - Developing scripts and utilities for building, testing and system maintenance. - Providing Linux / Unix expertise for team. Results: - Created fault-tolerant system architecture with traffic balancing. - Completed system redesign for using in Amazon Cloud environment (EC2, S3, with dynamic system scaling). - Public and internal services were moved to Amazon Cloud. - Created CI system from scratch integrating virtual machines creation on EC2, hosts registration in DNS, product building and making public releases / updates for production servers and clients. - Created Debian/Ubuntu port for server software. Means: OS: Gentoo/Debian/Ubuntu Linux, MacOSX, Windows2003-2008. Software: haproxy, keepalived, postfix, apache, mysql (+replication), powerdns, bind9, ldap, svn, trac, jboss, django, ejabberd, moodle, kayako, monit, nagios. Programming: python, php, shell, C++, STL, cmake, gdb, valgrind, maven.

Responsibilities: - Solving company's business tasks. - Planning and budgeting. - Solving of “high load” problems, including business trips to Moscow profile conferences and exhibitions. Supervision of file-exchange network project, in architecture and prototype developing (first and second generation). Results: - Created attestation system for engineers (RedHat, SuSE certification), introduced virtualization system for using in offices and datacenters. - Redesigned system infrastructure for getting more productivity and stability. - Created a preliminary concept of architecture for self-organising file-exchange network and some prototypes. - Now, peers.cn.ru is the largest file-exchange DC++ network in Russia. Means: OS: Debian/Ubuntu Linux Software: postfix, apache, nginx, proftpd, mysql, postgresql, bind9, ldap, svn, cvs, verlihub, jira, mantis. Programming: PHP, shell, python, C/C++, autotools, cmake, gdb, valgrind.

- Design and support of high-load systems. Support of network core infrastructure. - Worked on internal Linux kernel branch, solving difficult problems. Results: - Assimilated a new line of server hardware (Supermicro) by porting of adp94xx driver into Linux kernel 2.6.18. - Started wide using data storage solutions (Fibre Channel). - Created solution for services migration from server to server. - Applied several different solutions for increasing system/services productivity and stability. - Minimized downtime. Means: OS: Debian/Ubuntu Linux Software: apache, nginx, proftpd, mysql, postgresql, bind9, ldap, svn, cvs, mantis. Programming: PHP, shell, C/C++, autotools, cmake, gdb, valgrind.

Developing and supporting automatic acceptance test systems (VzLoader, AATS). Results: - The systems were successfully introduced in the QA department and significantly reduced required time for acceptance tests. OS: Linux. Software: VmWare, Linux, php, shell, mysql, apache.
