Hi.
My name is Bruno Calmels, I'm CTO at Macher IT, with headquarters in Neuquen, Argentina, with presence in US, Mexico and Spain.
We are a team of 5 developers, 3 graphic designers, one UX/UI expert, plus other staff. We have got broad experience in Ruby on Rails. We have many apps deployed in Heroku so we can help debugging that expensive app of yours.
If you are interested in working with us, feel free to contact us.
Hope to hear from you.
Regards,
Bruno
