What I'm looking for

I’m looking for a BI/Power BI role where I can build scalable semantic layers, optimize DAX, automate ETL with Airflow, and deliver secure dashboards using RLS for faster, more reliable decision-making.

I’m a BI Developer with 10+ years of experience designing scalable data models and interactive dashboards that streamline decision-making. I focus on delivering efficient, insight-driven BI solutions that help business growth and reduce manual effort.

In my recent role, I accelerated report rendering by building an efficient semantic layer between BigQuery and Power BI using a star schema. I reduced query load and improved responsiveness by migrating datasets into centralized Power BI Dataflows with incremental refresh, and I maintained stable performance on datasets exceeding 3 GB.

I automate end-to-end delivery by orchestrating ETL pipelines across BigQuery, Power BI Dataflows, and Power BI reports with Apache Airflow. I also optimize DAX performance and report efficiency by analyzing measures with DAX Studio and VertiPaq Analyzer, and by simplifying models using Tabular Editor and Measure Killer.

Security and governance are core to my approach: I implement Row-Level Security (RLS), role-based access, and manage secure delivery with dynamic subscriptions. I’ve built operational and analytics dashboards across finance, HR, risk, recruitment, and sales—often integrating sources like Snowflake, Qlik Sense, SharePoint, OneDrive, and Google Sheets.
