My in-laws own a small hotel in a third world country. Every dollar spent within their limited marketing budget matters. 10 months ago, my wife told me the amount they're spending each year on dynamic QR codes (for those that don't know - a dynamic QR code is a QR code that allows you to update the content without having to reprint the code; the information on the printout is static, but the data is fluid.). $641/yr. I looked at the company they were using and thought "I can do that better and cheaper." I spent the next 10 months in my spare time building a replacement for them so they can save a few hundred dollars a year. From static codes to dynamic codes to custom-built landing pages in a QR code, I built https://www.keboqr.com to solve their needs. Some of my favorite aspects of this web app, from a development perspective, include polymorphic class structure for each type of QR code, including Email, SMS, File Hosting, and more, custom API attributes to validate tier-based features, such as the number of dynamic QR codes you are allowed generate, and the role-based access control for all users in the users' organization. I encountered many challenges throughout the development of this app. Some of which causing me to scrap the entire application and start from scratch. Other challenges include not planning far enough ahead. The Account Overview page was more than 12,000 lines of code when I first implemented it. Fewer than two weeks later I redesigned the entire section because it didn't look or work how I was hoping.
