Working on inventory management for Zume’s automated order, prep and delivery platform. Technologies: Node, Express, Vue.js, Jest, REST, PostgreSQL, HerokuBack-end: Our team built a new microservice which exposed REST endpoints for storage and retrieval of inventory information. This new service was then gradually integrated with Zume’s monolithic order processing system to achieve functional parity with the previous inventory management solution while preventing any disruption to normal business during the transition.Front-end: Created tools for lookup and administration of orders and inventory data. These tools were released for use by new customers which had adopted Zume’s platform.
