Faiz brought me on to help out with this web wallet (https://github.com/LDEngine/msc-webwallet/).

I contributed to early API design which was unfortunately abandoned.
I helped Faiz with the client side encryption/decryption of private keys using HTML5 local storage
I have been testing various new features and assisting with debugging/improvement
I have started a fork to move the web wallet to django for maintainability as opposed to python's basic HTTP server


Additionally to grok grazcoin's mastercoin-tools (https://github.com/grazcoin/mastercoin-tools) I forked it and have started to write unit tests.
