I am a Power BI Developer with 5+ years of hands-on experience in designing, developing, and delivering interactive dashboards and data-driven solutions for businesses across different industries. Over the years, I have worked with sales, finance, operations, and marketing data to build meaningful reports that help decision-makers track KPIs, identify trends, and improve performance. My expertise includes data modeling, Power Query (data cleaning and transformation), DAX calculations, and building optimized, user-friendly dashboards. I have strong experience working with multiple data sources such as Excel, CSV, SQL databases, and cloud platforms. I specialize in transforming messy, raw data into structured models using best practices like star schema design to ensure performance and scalability. Some of my key achievements include: Developing executive-level dashboards that reduced manual reporting time by over 60%. Automating monthly and weekly reporting processes using Power BI and Power Query. Improving report performance by optimizing data models and DAX measures. Designing visually appealing dashboards focused on clarity and business insights. I focus not only on building reports, but on understanding business requirements and delivering solutions that provide real value. My goal is always to create dashboards that are simple, insightful, and actionable. I am committed to delivering high-quality work, meeting deadlines, and maintaining clear communication throughout every project.
