Summary
👤
Senior🎓
Top SchoolRohan Raj is a Lead Solutions Architect with nine years of experience designing and delivering data-driven solutions across enterprise environments, currently leading architecture at Celonis in Mannheim. He combines deep big-data expertise—Spark, Kafka, Hadoop—and cloud-native tooling on Azure, AWS and SAP SCP with practical DevOps skills in Terraform, Ansible, Kubernetes and Docker to migrate and stabilize large customer data lakes. Rohan’s background spans hands-on engineering (Python, Java, .NET, NoSQL, PostgreSQL) and applied data science from a master’s in Big Data and Business Analytics, including a master’s thesis that built an end-to-end UX analytics framework and migrated workloads from AWS to Azure. He has a track record of improving platform performance and isolation—helping 400+ customers move to dedicated data lakes—and enjoys working in dynamic multinational teams to translate complex requirements into scalable architectures. Not obvious from titles alone, he blends product-focused UX analytics experience with core platform engineering, making him effective at both insight generation and operational delivery.
