Hire the Best Data Analysts in Berlin, DE

Your dashboards are slow, your data sources don't agree with each other, and leadership has stopped trusting the numbers, I rebuild the analytics layer underneath, using dbt on Snowflake or BigQuery, so your team makes decisions on data you can actually defend. With over 11,000 hours logged and 80+ projects delivered on Upwork, I've worked with growth-stage SaaS startups, fintechs, retail and eCommerce operators, real estate firms, and global research organizations to design dbt-based data models, build end-to-end ETL/ELT pipelines, and deliver BI systems that eliminate reporting delays. A few projects I've led recently: CGIAR - Built a centralized enterprise analytics platform on Microsoft Fabric and Power BI, replacing fragmented reporting across a global research consortium. Sojo Industries - Designed a continuous intelligence layer delivering real-time visibility and enterprise-grade analytics for retail operations.

ECAP - Delivered analytics and financial modeling for a private real estate investment firm managing strategic property portfolios. Voice AI Automation Company - Integrated Stripe, HubSpot, GA4, Google Ads, Linear, Pylon, and MongoDB into a unified, business-ready data model for an AI-first SaaS company. How I work across the analytics engineering stack: Data Modeling and Transformation - I build dbt models on Snowflake and BigQuery that turn raw, multi-source data into clean, analytics-ready datasets. Strong focus on testing, documentation, and modular design so your data layer stays reliable as it scales. Data Engineering and Pipelines - I design and maintain ETL/ELT pipelines using SQL, Python, and Apache Airflow across AWS, GCP, and Azure. Whether you need to ingest from APIs, sync SaaS tools, or move data between warehouses, I build pipelines that don't break when your business grows. Business Intelligence and Dashboards - I build interactive dashboards in Power BI, Tableau, and Looker Studio that turn analytics-ready data into clear, actionable insights for stakeholders. KPI tracking, executive reporting, self-service analytics — designed for the people who actually use them. Cloud and Warehouse Expertise - Deep work across Snowflake, BigQuery, PostgreSQL, and Redshift, with hands-on experience integrating GA4, HubSpot, Salesforce, Stripe, and other SaaS data sources into unified warehouses for cross-functional reporting.
