4MDG builds a master data management (MDM) platform tailored for SAP environments, particularly in retail. The stack reveals a hybrid architecture—Ruby on Rails + PostgreSQL for the core application, complemented by a data pipeline layer (Python, NiFi, Elasticsearch, Kibana) for governance and reporting. Active hiring in data (4 roles) and a proof-of-concept for streaming frameworks signal a shift toward real-time data quality monitoring and scaled pipeline operations, moving beyond static master data management.
