I'm sysadmin and software developer with more than a decade of experience (see CV for details).

For ten years as ISP lead engineer I've helped to grow a small ISP from a hundred customers to few thousands. For last few years I work remotely as independent consultant and I'm mostly focused on building high performance web serveres (nginx, varnish, unicorn), application deployment (capistrano), cloud/virtualized servers (Amazon EC2, Xen Virtualization), configuration management (chef/puppet) and server monitoring (monit, nagios, munin).

To enquire about my availability please send message to enquiry ( at ) alexeydemidov ( dot ) com.

comment Reduce Gitlab memory footprint
Please note that SideKiq uses threads and htop shows threads as separate entries in output by default. Having 25 entries each showing 300MB of VIRT memory doesn't mean that SideKiq uses 25*300MB = 7.5GB of memory. If you switch to Tree View with F5 or hide threads with H you will see more real memory consumption.
