Fer Martinez

I am a senior BI and business data analyst with a strong track record building data products and analytics that improve merchant and partner performance. I combine SQL and Python engineering with dashboarding to deliver actionable insights for commercial teams.

At Tienda Nube / Nuvem Shop I led initiatives around OKR tracking and an App Store Review and Rating automation that increased review volume and average rating, using AWS, Postgres, S3, DBT and orchestration tools. My work focuses on end-to-end data solutions that move key business metrics.

At Pedidos Ya I designed analyses and models around discount adoption, a Discount Recommendation Engine, and loyalty program work that directly informed partner revenue strategies. I routinely build reproducible pipelines with Airflow, BigQuery and Appscript automations.

I bring fluent English and native Spanish communication, formal training in data science and Python, and a pragmatic, product-minded approach to analytics. I enjoy applying machine learning and data engineering practices to solve commercial problems and scale impact.
