At Mu Sigma, I used SQL, Python, Excel, and Power BI to analyze operational data and identify drivers of rising customer churn. I implemented a solution that reduced churn by 15% and developed a Power BI dashboard that reduced manual reporting effort by 45%.

At Mu Sigma, I also led Citigroup’s data governance framework through the Data Concern and Remediation Management System, resolving 42 data concerns and defects. In my projects, I benchmarked optimizers on CIFAR-10 with ResNet models in PyTorch and developed an agentic visual reasoning system using vision and language models.
