Top SchoolOzan Tanfener is a senior software engineer based in Stockholm with a decade of experience building cloud-native backend systems, microservices, and data pipelines across AWS and GCP. He has delivered production-grade solutions from embedded OCI-based microservices on industrial gateways to large-scale data processing with Apache Beam and Dataflow handling tens of millions of events. Known for pragmatic engineering, he raises test coverage and reliability (e.g., raising coverage to 80% and implementing zero-error data backfills) while integrating complex third-party systems like banks and payment providers.
