I have 1+ year experience in Titanium Appcelerator and I'm using it to develop cross platform applications for iOs and Android. I can write native modules for both platforms on ObjC and Java. Also I'm using NodeJs + MongoDB/Mongoose + Express to create backends for my apps. I can host project on Heroku, Mongolab and other cloud services. I have profiles on Github and Bitbucket. I know JavaScript, and I can write on ObjC, Java, C/C++ (Qt) and PHP.
