PlayHatke App

Worked on a app to play games with bids.The amount of bit was small and the

concept was to have 90% of the participants win something depending on their global position. Backend was made on nodejs with mongodb and redis. Redis was used to implement delayed queue for rewards when a game ends.The app is made on flutter and everything is hosted on aws. The promotion website is made on nodejs with ejs template.

Automating the prizes was the main problem as the calculation algorithm was tough to implement but we tackled it and made the solutions possible in nlogn complexity.We also used delayed queues for the game queue and sockets for real time games.
