What I'm looking for

I seek a Data Scientist/ML role applying Python, ML and generative AI to build production models that deliver measurable business impact within collaborative, product-focused teams.

I am a data scientist focused on machine learning and Generative AI, building production-grade models that drive measurable business impact.

At HDFC Bank I fine-tuned the LLaMA instruct model to create a leadership Q&A assistant, developed a WhatsApp chat-banking propensity model and fraud-detection classifiers, contributing to projects cited with an estimated €18.5M impact and a merchant-retention model delivering €13M in preserved transaction value.

Previously at ReNewPower I built XGBoost forecasts for 120 solar plants and automated penalty and error reporting across wind and solar assets, improving operational accuracy. I hold certifications including Machine Learning (Coursera, Andrew Ng), Advanced Python, Power BI, and Data Science & SQL.
