Hi guys. I'm the founder of Coinflash, a web app that rounds up your spare change into Cryptocurrency. After launching 1 month ago on the front page of Product Hunt, we have reached around 10k users. We've been featured on Mashable, Lifehacker and Springwise.
Coinflash rounds up your spare change into Bitcoin and Ethereum, it's Acorns for Cryptocurrency. We want to expand to other Altcoins through the Shapeshift API. I have a front end person building the front end component, the mockups are attached. We are half way through the backend implementation but the Java programmer had to take another job. We took good notes, documented everything well. If you are experienced with API and Java and hopefully cryptocurrency, then this can be a good fit! Our servlets run on a AWS instance running Tomcat and mysql. I have a development machine you would work on. By
This is a one time project that could easily turn into many projects.
