Wunder is the first such personalized app for new parents, designed to give parents the right information at the right time and boost baby's cognitive development. It can used to track baby's critical milestones, recommends developmentally-appropriate activities that combine fun and learning, and supports emotional bonding. I worked here for more than 1 year, mainly responsible for the backend development (on AWS). Ranging from managing database, integrating AppSync, deploying machine learning models, to writing Lambda script for controlling business logic. I also have a touch on the device firmware and middleware (written in Python) sometimes.
