Hello World :D! My name is Yichen Lin, a CPA-eligible MBA in Accounting candidate at Stony Brook with a background in applied math and statistics
At a New York law firm, I reviewed about 200 invoices a week against internal controls and caught a recurring issue causing duplicate payments, then helped fix the process. As a restaurant general manager, I analyzed sales and margins to recommend a menu change that raised gross profit by 6%. I like finding where the numbers don’t line up and figuring out why, and building small tools, like the ones below, that make that easier.
