What I'm looking for

I'm looking to build practical machine learning and GenAI products, especially in healthcare prediction, RAG systems, NLP, and conversational AI, while growing through hands-on engineering collaboration.

I'm building a Brain Aneurysm Prediction pipeline at Alkem Laboratories using machine learning and Vision AI, reaching 88.4% precision on test data. I integrated LIME to provide transparent, per-prediction explanations for healthcare professionals.

I've developed RAG-based conversational AI projects including a business loan voice assistant that combines Faster Whisper, FAISS, Groq LLM, Kokoro TTS, LangChain, and Streamlit. I also built a stateful LangGraph chatbot with persistent SQLite-backed conversation memory and real-time response streaming.

My work spans EDA, feature engineering, class-imbalance handling, model evaluation, hyperparameter tuning, and data visualization. I work primarily with Python, scikit-learn, LangChain, Hugging Face, vector stores, and LLM applications.
