I've done a mix of utility coding (some web services), and DevOps work in Ruby. A lot of it was by way of Chef, but I know enough Ruby to get around comfortably in the code base of any Ruby application. I've also spent some time instrumenting Rails code for consumption by other tools (notably Riemann)...

I have a little bit of experience working in Javascript/Coffeescript, but don't consider myself to be an expert. I've built some neat little toy visualizations in d3.js, and was working with the Oculus Rift and Razer Hydra in three.js. 

At one point I was doing front end work for a startup that never quite got off the ground, so I ended up with some experience building at least sections of a single page application with react, bower, semantic-ui, lunr, and some other bits and pieces.

Have a bunch of experience from the same project in setting up javascript build systems.

Have recently been doing some work in Python. Built a lightweight agent for executing packaged neural network and machine learning applications (experiments) based on a simple configuration file. 

I've also been playing with numpy, scipy, sympy, matplotlib, and vispy to get a better understanding of machine learning math and visualization...

Limited professional experience, but I learned it a long time ago, and it probably informs my coding style to some extent. Would probably be able to assist in coursework level C++, and general debugging of application code, but not a lot beyond that without more practice.

Did some graphics work (ray tracing, opengl) for a course a year or three ago...

First language I learned after BASIC. I can still write it, a bit, but don't use it often enough to be really good. No problem in assisting with debugging, coursework, etc. Might want to look elsewhere for in depth optimization, etc...

Have only used this a little bit, in conjunction with writing filters for Riemann metrics... but quite like the language.

Have worked on a lot of projects that use Rails, but haven't written anything with it from the ground up. I can debug, instrument, refactor existing Rails code, but am not familiar enough with the framework to create something new...

Little bit of MySQL, mostly installation and configuration, install automation with Chef. Can write queries if need be.

Spent a while working with a particularly uncooperative MongoDB setup. 

Familiar with clustering, sharding, failover, deployment, queries, and a bunch of other bits and pieces.

Particular focus on the DevOps side of things.

This is what I do, essentially. If it involves automating, deploying, failover, scaling, planning, security, continuous integration, networking... whatever, basically... then I've done it, built it, or at very least, heard of it....

Lots of experience using Chef to build a huge system for configuration management. Have not used it in depth recently, but have spent 100's of hours with it, so I've got a solid grasp on things.
