I care very little about what technologies are used. I have my preferences, as all developers should, but I can and will build whatever you need in most any language or technology you wish. When it comes to mobile, I prefer hybrid technologies so as to minimize number of code bases. I am capable and willing to do DevOps, Full App/Site Creation, code optimization, facelifts, the whole nine. I have been doing Android development since 2003, both natively and HTML5 driven. I am comfortable utilizing Node, Java, or Golang equally on the backend, and am familiar with all front end frameworks. Rates are negotiable.
