The problem Re-Konnect solves

Problem: Every year thousands of students graduate and with increasing student capacity, it's getting harder to keep track of what each student has been up to and what they have accomplished. Keeping track of students on a college basis helps solving this problem, as the college can stay updated on what each individual has been upto without inquiring individually.
Because of this, colleges and its students can also reach out to the alumni regarding events or to get some help.

Challenges I ran into

There were plenty of challenges I ran into. The first being, authentication system. This was easily fixed using Django's built-in authentication system. The second problem was encountered because of using built-in authentication system. The built-in system came with pretty restrictive use cases and so, I had to customize entire user models and forms using widgets.
