My fiancee is a talented cosplayer (https://en.m.wikipedia.org/wiki/Cosplay), but she is also one of the most disorganised persons I know. I decided to try and develop a SaaS web application that would be useful to her and other cosplayers - as well as giving a shot at developing something more ambitious than my usual side projects.

You can find the result at https://cosflowy.com/

I used the Meteor JS framework (https://www.meteor.com/) - I had a great experience with it and I don't think it gets enough love - I know it might not scale as well as other, lower-level solutions but it got a beginner web developer like me to put together and ship a usable product, which I think is no small feat.

I used Meteor's proprietary hosting service, Galaxy, which is pricier than something like Digital Ocean with the same specs but I didn't want to spend too much time on devops, so I'm willing to pay the extra for one-click deployment out of the box. I also used Mlab to host the mongo database, Google Cloud to host user-uploaded files, and Stripe to process the subscription flow.
