Case study: Online voting app

Hi!
As part of my portfolio, I made a case study on an online voting app. Here is the link for the case study: https://medium.com/@vigneshvelu/case-study-voting-app-54db56bd41d9
I looked into what makes an election system, why we need online voting, what do voters need, how to achieve that and furthermore.
Feel free to comment about it. Thank you!
