At Oetker Digital GmbH, I built and maintained distributed data platforms on Google Cloud Platform using Airflow, Terraform, and Kubernetes. I also built secure retail data ingestion and transformation pipelines on GCP and Azure, and enforced IAM and security policies across platform and warehouse layers.

At The Adex, I built and maintained a data management platform handling terabytes of data daily, and developed real-time profiling on a microservices architecture. Earlier, at Nokia Networks, I built and maintained a scalable analytics platform for telecom data and worked on a Hyperledger Fabric blockchain platform. I hold the Golden Kubestronaut designation and Google Cloud Professional Architect, Security Engineer, and Data Engineer certifications.
