About Samuel

Technical leader with 15+ years designing and governing data & AI systems at scale. I set technical standards, resolve architectural conflicts across teams, and build the infrastructure that makes data platforms reliable, cost-efficient, and sustainable long-term.
Hands-on across the full stack: data ingestion, transformation, serving, and ML pipelines — on BigQuery, Spark, Databricks, Snowflake, and AWS. I've led multi-team alignment at MediaMath (4 global regions), governed data architecture at AdInMo across competing product lines, and standardized measurement frameworks at Betsson across conflicting business domains.
I work best in environments where there's no single source of truth yet — and where the job is to build one, get cross-functional buy-in, and make it stick.
