As part of Rappi’s catalog backend team, we engineered the core infrastructure for their Consumer Packaged Goods (CPG) division. Acting as the central hub for product data, we developed APIs with NodeJS and Go to handle data synchronization across multiple services using Kafka and SQS. We integrated ElasticSearch to enable real-time search capabilities and built internal admin tools in React and Redux for product managers and merchants. We provided end-to-end support, including performance tuning, developer mentorship, and implementing business-critical features to streamline CPG operations across LATAM.
