Hi, I'm Sergei.

I'm an independent data consultant in Stockholm, working under my own banner — Seppl. I design and build cloud-native data platforms on Microsoft Fabric and Azure Databricks — Lakehouse and medallion architectures, ETL/ELT pipelines, and Data Vault / dimensional models.

With 10+ years turning messy data into reliable, business-ready products across healthcare, public sector, and enterprise, I help teams make faster, data-driven decisions. Currently architecting greenfield Fabric platforms, and leaning into AI-assisted engineering.
