I've built and deployed end-to-end ML systems, from a 970K-record subscriber churn engine achieving 0.956 PR AUC to an NLP complaint-risk platform with 89.4% accuracy and 0.865 Macro F1.

For seven freelance clients, I've architected n8n automation pipelines and LLM-powered data-extraction tools that reduced manual lead-processing time by about 20%. I've also delivered three production web applications and led hands-on workshops on agentic workflows and structured LLM integrations.

I built QUANT-ENGINE, combining XGBoost, Attention LSTM, macroeconomic signals, and a Streamlit dashboard for NSE stock-price inference. At Krea University, I also orchestrated OnCampus, a community and utility platform serving 1,000+ students that reduced cafeteria peak wait times by about 30%.

I'm a Data Science undergraduate at Krea University with a 8.94/10 CGPA, focused on predictive modeling, NLP, and production ML pipelines. I bring experience in Python, SQL, scikit-learn, LightGBM, PyTorch, FastAPI, Streamlit, and React, alongside bilingual teaching experience in Tamil and English.
