I am a developer, though not a ruby dev. Based on my experience, one hack to increase your chances is to have a targeted relevant project on Github. So, for e.g if you are applying to an e-commerce shop, have a simple e-commerce project on github. Then when you are applying to a similar shop, you can fork/mod it to make it more relevant. If you know their market, you can then share some ideas you may have that will have a positive impact on their website, performance, market penetration, SEO, whatever. Screenshots and videos will just make them melt.
