Hi, I’m Marcus. A data professional specialized in building reliable analytics systems and decision-grade datasets. I help companies structure data foundations that actually support reporting, forecasting, and business decisions. My work focuses on data modeling, SQL logic, metric definitions, and transformation layers; the part of BI that makes dashboards correct, not just visual. I work across: SQL & Data Modeling: fact tables, dimensions, KPI logic, performance optimization Analytics Engineering: transforming raw data into clean business layers Business Intelligence: Power BI, Metabase, Apache Superset, Looker Studio Python: ETL, automation, data validation, pipeline scripting Data Quality & Governance: consistency checks, metric validation, reporting reliability I’ve worked with revenue analytics, pricing logic, operational reporting, growth metrics, and large production datasets; building analytics foundations that scale and stay accurate over time. If your problem isn’t “a chart” but structure, trust, or correctness of data, that’s where I add value. Let’s connect.
