Product: Afghanistan Premier League Auction. (ITW)

APL auction was one of my shortest and toughest project yet by far. We got this project 3 days away from actual auction. There are total 11 rounds, 1 minute per team to choose a player. Each round will different base on player buckets (batsman, bowler, all rounder and so on). team owners have a dashboard with all data of each rounds and the players they selected with their budget. A big screen for media and audience with sequential timer, selected player info and the history of players selected. We used Pubnub to get realtime status of the selection window for each team and also the realtime selection for the players. Since it was an media event, it was very crucial for the application to work with different rules. we have used scheduler to lock each rounds once the timer window closes. The team of 3 developers including me stayed in the office for 3 days and built the application successfully and given support for whole live event. During the live event there was something unexpected happened and the client wanted to add 2 more rounds, when the the 3 round is live. We have pushed changes to accommodate those 2 rounds during the live auction and managed to add the new requirement.
