It took 6 weeks, but I'm finally done building the minimum viable product for Cheat Sheet Maker. I worked mostly nights and weekends, and I coded the whole thing in Ruby on Rails since that's that I'm the most comfortable with. In hindsight, there were a few features I built that probably could've waited until later. But I'm excited to start talking to customers and see what they think about the product so far!

I've read so many times that you should solve your own problem, and so last week I sat down to think about all the problems in my life.

It turned out that I had quite a few problems worth solving, and the most interesting one led me to the idea for Cheat Sheet Maker!
