Problem: My experience taking audio tours at various museums showed the use of antiquated and expensive hardware. Most alternate solutions used mobile apps which are inconvenient to download and take more time to release.
Project: I went about developing a web app that allows anyone to quickly create an audio tour for free:

I also integrated Amazon Polly to automatically generate audio based on text inputs. This further increases ease of use by eliminating the need to record and edit audio.
It was a great learning experience since I learned rails from scratch and don't have a background in programming. Now to see if I can get more people to use it!
