    I'm an expert software engineer with 8+ years of experience. My languages of choice are Python, C and Go. Other languages I had experience with are C++, Java, Scheme, Javascript (with Node.js), Perl, PHP. My main expertise is building highly available and efficient backends for high-traffic applications that handle hundreds and thousands requests per second. I'm in sympathy to OSS ideas and have contributed to a wide range of open source projects – VLC, Git, Nginx, Django, GDB, etc. I'm interested in distributed, concurrent and fault-tolerant systems. Currently I'm reading SICP and solving exercises from this great book. Source code for solved exercises is also available on my Github page.  less
