Can you share a memorable success story from one of your indie projects?

I don't have a indie project success story, but i do have one with a project which i am working on with my state government, i am taking this example because its developed solely by me. Its an EWS (early warning system) which detects students in Delhi, India who are at risk of dropping out of school due to several reasons. Last year we intervened and prevented 410344 students from dropping out of school!
