Android and C++ programmer

Belarus - Tests: 4

I am a student who is very passionate about programming. I really love algorithms and c++ - these are my favorite. I took part in many different programming contests in high school, so I have good knowledge of different algorithms. I can program a c++ application, a simple website or an android application. And, by the way, I am quite good at helping students with their courses too. Also, although English is not my first language, I love it very much. I read books in English and volunteer as a translator of free online courses. If you need a programmer or a translator - I would be glad to help! P.s. 1 week warranty: If you hire me, and you find a fault in my job within a week after its submission, I guarantee that I will fix whatever problem you may have for free!

Douglas H.

Douglas H.

Ruby developer

United States - Tests: 7

Ruby has been my main language for a number of years now. I also use Javascript frequently (on the client and server), and Java and Perl when the need arises. I use Ruby on Rails for a number of projects, but a large part of my Ruby work is outside of Rails, as ruby is now my primary language. I have a great deal of SQL experience but have been using noschema databases for most new projects for a couple of years (specifically MongoDB). I have been working in a freelance environment for a number of years, and have a multi-machine linux-based network with constantly running infrastructure suited to tackle any task as it arises. I do a reasonable amount of system administration for my own pleasure or in the cloud for clients, and also run and administer client production deployments myself.
