Senior🎓
Top SchoolOscar Björhn is a Senior Data Architect & Engineer with 13 years of experience designing cloud-native data platforms and AI solutions across banking, retail, and consumer sectors. He has built and led data teams from the ground up, delivering Snowflake- and Databricks-based warehouses, Data Vault 2.0 implementations, and production LLM/agentic applications while driving FinOps and governance practices. Known for pragmatic platform design, he combines hands-on engineering (dbt, Prefect, Snowpark Container Services) with product ownership and CI/CD-centric architecture to scale data capabilities. A frequent speaker and recognized data leader, he presented Snowpark Container Services to 1,800+ attendees at Snowflake Data World Tour 2025. An often-overlooked strength is his track record of rapid regulatory and high-throughput deliveries—such as a compliant banking DW processing tens of GBs daily under tight deadlines. Based in Sweden, he now leads data architecture at Yellow Elk, continuing to fuse operational rigor with AI innovation.
