I am a Power BI Trainer and Data Analytics Professional with 3+ years of real-world industry experience in Business Intelligence, Data Visualization, and Data Engineering. My teaching approach is practical, industry-focused, and job-oriented, designed to help students and professionals confidently apply Power BI skills in real business scenarios.
I specialize in Power BI Desktop and Service, data modeling, Power Query (M), advanced DAX, and dashboard storytelling, with strong exposure to Microsoft Fabric, Azure Synapse Analytics, SQL, Python, and Pyspark. I focus on teaching not just how to build reports, but why certain models, DAX patterns, and performance techniques are used in real companies.
My sessions are hands-on and project-driven, covering end-to-end solutions — from raw data ingestion and transformation to optimized dashboards, security (RLS), and deployment. I also provide interview preparation, real-world use cases, and best practices that align with current industry expectations.
As a trainer, I am known for clear explanations, patience, and a student-first mindset. I enjoy mentoring learners from different backgrounds and helping them transition into job-ready Power BI, BI Analyst, and Data Analyst roles with confidence.
