Senior🎓
Top SchoolIoan Sendroiu is a Senior Data Analyst with 11 years of experience building AI-first analytics stacks for e-commerce, currently leading a modern rebuild at The Conqueror Challenges using Claude Code, BigQuery, dbt, Evidence and Airbyte. He designs end-to-end pipelines, warehouses, semantic models and internal data APIs, and runs daily refreshes across orders, ads and GA4 for multiple business units. Previously he single-handedly built a 220-table Power BI estate with 1,200+ measures and executive-facing reports, demonstrating deep expertise in semantic modeling, DAX optimization and deployment ALM. His background spans data engineering, cohort and retention analysis, and media buying at scale, giving him rare fluency across analytics, marketing and operations. Based in Bucharest, he pairs an Automatica si Calculatoare foundation with hands-on production experience—often reducing weeks of engineering work to a single SQL query. He’s attracted to pragmatic, measurable improvements: rebuilding fractured ETL into modular warehouses and exposing curated data via REST/MCP for cross-team reuse.
