MyMalls is a cross-border shopping facilitator. Members receive a physical shipping address (suite number) in the US. MyMalls partnered with DHL to create a user friendly service that forwards packages from their Miami warehouse right to the buyer's front door. Shopping online at stores across your country’s borders presents challenges. Some shops don’t ship internationally, others charge exorbitant shipping fees. Worst of all, the logistics of getting packages through customs is always a headache. I developed new features and integrations for the applications, as well as bug fixes and some front-end fixes. Collaborated with stake-holders and project managers to deliver a high-quality software solution. The project was successfully launched and is growing with more than 10k users already registered. Technologies used in the project: Ruby on Rails, React Native.
