PowerMeals is a high-growth Swiss meal subscription service requiring a robust, scalable platform to handle complex user preferences, delivery logistics, and recurring payments. The primary goal was to reduce friction in the subscription process while handling complex business logic such as varying delivery surcharges and international localization.
