## About

I build data systems that drive decisions — not just dashboards\. At ZS Associates, I own end\-to\-end analytics pipelines for a global pharma client: automated incentive compensation workflows that cut turnaround by 95%, Python\-SQL pipelines processing 100K\+ records/month, and Power BI dashboards that contributed to a 10% market share gain\. At DRDO's CAIR, I built a fully offline LLM\-based Q&A system using LLaMA 3, RAG, and Haystack — moving from prototype to deployed system in 6 months\. What I bring to BFSI: → Analytics pipelines at scale \(the same logic that powers IC compensation models applies directly to credit scoring, risk modeling, and rewards optimization\) → ML in production — not just notebooks → Business storytelling — I translate model outputs into boardroom\-ready recommendations I'm actively targeting Data Analyst and Data Scientist roles at companies like American Express, Barclays, Blackrock, and Mastercard — where analytical rigor meets real financial impact\. Core stack: Python · SQL · PyTorch · LangChain · Power BI · Tableau Open to referrals and conversations\. DM me or reach out at gursehajbir2027@gmail\.com
