I developed the "WS - Wine and Cellar" app from scratch, and subsequently published 31 versions in the Google Play Store. In 2012/2013 "WS - Wine and Cellar" went from ranking #332 to being the #1 Android app for wine aficionados, with 350K+ downloads.With the help of a visual designer, I iterated over the following app development life-cycle:• Analyze user feedback+analytics from production version• Define scope for next version: bugs to fix, new features• Develop next version using Java / Eclipse / XML Layouts / Open source libraries / Testing tools• Test (automated and manual)• Beta test with core users• Publish in Google PlayI followed the same process, and did the same work to develop the "Wine Dictionary" app, and published 8 versions. In Sept. 2014, this app is the #4 ranked Android wine app with 137K+ downloads, 960+ ratings, and an average rating of 4.06.
