Marcus A.

Hi, I’m Marcus. I help startups and scaling companies turn messy, unstructured pipelines into decision-grade analytics.

Many businesses have beautiful reports that nobody trusts because the underlying data is broken. My expertise lies beneath the surface: data modeling, SQL logic, transformation layers, and metric definitions. I fix the structure so you can trust the charts.

Core Expertise:

Analytics Engineering & SQL: Building robust fact/dimension tables (using dbt, Snowflake, Databricks), optimizing queries for cloud databases (like ClickHouse, Redshift), and creating a single source of truth.

Business Intelligence: Translating complex logic into actionable reports via Power BI, Looker Studio, Metabase, and Apache Superset.

Python & Automation: Scripting custom ETL pipelines, data validation, and workflow automation (e.g., n8n, custom Slack/API integrations).

Data Quality & Governance: Implementing consistency checks and metric validation to ensure reporting reliability over time.

Where I Add Value:
I've helped international, remote-first teams scale their revenue analytics, pricing logic, operational reporting, and growth metrics. Whether you need a rapid MVP to capture data or a complete overhaul of large production datasets, I build systems that scale and stay accurate.

If your problem isn’t simply “making a chart,” but rather structuring and trusting your data, let’s connect.
