Hello,
I've read you request very carefully. During the last two years I hve been working in development of different kind of solutions for criptocurrencies.
I created online wallets for BTC, automatic event-driven payments in BTC, account checking and notifications fired on BTC payments, fair exchanges USD/BTC based on BTC price avg, payments gateways in BTC, I mean a long and boring etcetera.
My name is Juan Manuel, and although I am new at Freelancer I am not new as coder. I am a Software Architect with +25 years of experience. Please take a look to my (still ongoing) profile.
I am vey interested in your project. Please, let's talk about it. Contact me at anytime.
Regards.
Juan Manuel
ps: Since the budget of your request doesn't make sense (I suppose you only wanted to get some candidates with who arrive to a later agreement) I bidded as if it was my hourly price as professional for this kind of development.
