Grigorii Kosarev

Hi! I’m Grigorii — a data analytics engineer and digital nomad based in Barcelona, with a background in economics and a strong focus on scalable, high-impact data systems. Over the past few years, I’ve worked on ETL/ELT pipelines, analytical tools, and event-driven architectures that help companies make better, faster decisions. I enjoy connecting data engineering and analytics — designing Airflow + dbt pipelines, developing internal tools with FastAPI or Streamlit, and setting up monitoring with Grafana or Metabase. My experience spans from corporate analytics at Kaspersky to high-velocity projects in fintech and crypto. Currently, I’m expanding my expertise in AI-driven automation and data architecture design. I love projects where I can bring structure to chaos — turning messy data into reliable insights and tangible business value.
