The last year I worked hard on launching my first production project, Advanced Scheduler. It is an Heroku add-on providing task scheduling as a service with an increasing number of higher value services on top. It aims to be more flexible, reliable and easy to use than existing solitions. The beta phase has just ended and it is now generally available on the Heroku Marketplace:

I'd love feedback and suggestions on how to make it better. Thanks!
