Fun question to reflect on answering! It's all about teamwork! I'm defining "impact" as user count: About 8 years ago I built (as tech lead) a very simple commenting system that is seen by about a million people a day with several thousand DAUs. I also made a triple-A cricket video game that was huge in India (batsman and umpire AI, some physics). Made (as enterprise architect) a mobile banking app for a bank with several million customers.
