Deep technical knowledge implementing supervised and unsupervised ML algorithms: linear/logistic regression, neural networks (CNN, RNN, LSTM, Transformers), k-means clustering, DBSCAN, decision trees (CART, C4.5), and ensemble methods (Random Forest, XGBoost, LightGBM, CatBoost)
Proven experience building and deploying Agentic AI and LLM-based solutions using:
- LangGraph for complex agent orchestration and state management
- LangChain for chain-of-thought reasoning and retrieval-augmented generation (RAG)
- Agent Development Kit (ADK) for enterprise-grade autonomous agent development

Beneficial Skills & Qualifications:
