Karthik Nagesh

I've delivered production ML systems, predictive models, NLP pipelines, and GenAI solutions across banking, consulting, and healthcare.

At Bank of America, I deployed a gradient-boosted fraud detection model scoring 40M+ daily transactions, increasing fraud capture by 22%, reducing false positives by 18%, and preventing $12M in annual losses. I also built 150+ predictive features and re-architected a credit-risk scoring pipeline from hours to under 10 minutes.

At Accenture, I delivered 10+ end-to-end ML solutions that generated $8M+ in combined savings, including a churn model with 87% precision and an NLP pipeline routing 500K+ monthly support tickets. I translated model outcomes into Tableau and Power BI dashboards for senior leadership while mentoring junior analysts.

I work across Python, SQL, Spark, Databricks, AWS, Azure, MLOps, and model governance. My projects include a RAG financial assistant and distributed fraud detection models, and I hold AWS Machine Learning Specialty and Azure Data Scientist Associate certifications.
