Subbu Kolli

I am a results-driven Financial Data Analyst and Power BI Developer with over 6 years of experience leveraging data to drive strategic decisions across Finance, Sales, Marketing, and Operations. With hands-on expertise in Power BI, SQL, Excel, and DAX, I specialize in designing scalable dashboards, optimizing reporting workflows, and turning raw data into actionable insights.

Currently at PwC, I’ve led the development of executive dashboards tracking $50M+ in Sales & Marketing spend, enabling a 25% improvement in ROI visibility. I’ve also automated Opex/Capex reporting using Power BI and DAX, reducing manual effort by 40%, and collaborated with business stakeholders to optimize legacy reports that delivered $30M in operational savings.

My career has spanned industries including Telecom, E-commerce, Banking, and Manufacturing. At Accenture, I built telecom churn and revenue dashboards that directly supported a 20% increase in customer retention. At Amazon, I managed GRIR and GL reconciliation processes for $20M+, reduced close-cycle backlog by 30%, and ensured 100% audit-ready compliance.

Beyond the technical tools, I bring a business-first mindset—deeply understanding stakeholder needs, aligning reporting with financial strategy, and proactively contributing to forecasting, budgeting, and resource planning processes.
