Hi, I'm definitely interested in your project. However, I would need a more thorough description of you requirements to submit a quote. I have a strong security background and know quite a lot about the bitcoin world besides of being an experienced ruby developer.
Good evening.
I am computer enginer with most web development made in RoR, so I am able to do what you need. Need more details on what you pretend, though, because the description stills too much vague.
Thanks in advance.
Best regards,
