I am Maham Marashizadeh, president of Nimblytica, a data and business intelligence consultancy. I build Power BI dashboards, SQL data models, Python automation, and Azure Data Factory / Snowflake pipelines that turn messy source data into reliable, decision-ready reporting. As a Senior BI professional at a large healthcare organization, I have delivered enterprise dashboards, KPI frameworks, and ETL processes used daily by operations and finance teams. My work covers data warehouse design, DAX and Power Query optimization, report performance tuning, workforce analytics with Visier, and automating manual Excel processes end to end. I hold a degree from CSUN plus eCornell certificates in Machine Learning and Python. Whether you need a new dashboard, a pipeline rebuilt, or recurring reporting fully automated, I deliver clear, documented, maintainable solutions with fast communication.
