What I'm looking for

I'm looking to continue building scalable ML and Generative AI products that solve high-impact business problems, from problem framing through enterprise deployment, alongside cross-functional teams and global stakeholders.

At Novartis, I build and deploy production ML and AI products for pharmaceutical marketing and decision-making. My HCP targeting engine delivered 5–10% incremental Rx lift, 3–5% digital promotion uplift, and 3.5X ROI improvement.

I built an Agentic RAG chatbot using LangGraph, Portkey, FastAPI, and Pydantic LogFire that reduced repetitive analytics turnaround by 20–30%. I also deployed drug-shortage prediction across five global markets and created MLOps workflows that reduced operational overhead by 30%.

Across Novartis, WNS Global Services, and Sapieo Software India, I’ve applied causal inference, forecasting, predictive modeling, and marketing-mix modeling to drive measurable commercial outcomes. I’m continuing to expand into Generative AI, LLM orchestration, and scalable decision-ready systems.
