Adrian Wadowski has worked in e-commerce and written code since 1998. CartHacker started in 2026 from the questions store owners and clients kept asking him: why is my store slow, why do shoppers leave at checkout, how to prepare product photos, what should I fix first? Every tool and plugin available answers one of those questions.
