    Inventory Optimization (Retail Client): Designed and production-ized a time-series-forecasting pipeline with XGBoost, pandas, NumPy and scikit-learn to predict SKU-level demand and optimize inventory allocation. The solution cut stock-outs by 20 %, reduced overstocking by 30 %, and, through regression-based driver analysis, continuously refined the retailer’s inventory algorithms for sustained improvement.Model Validation: Conducted A/B tests on product performance and rigorously validated machine learning models to ensure reliability before deployment, proactively identifying issues.Automated ML Pipeline with Airflow and AWS SageMaker: Developed and implemented an Airflow data pipeline using Airflow and AWS SageMaker for model trainingand deployment—streamlining operations and saving 1–2 hours of manual work per monthMulti Agent AI System: Built an end-to-end multi-agent AI system using Groq api, LLaMa 17B LLM, Tavily, LangChain, and LangGraph to enable autonomous task coordination and intelligent decision-making across agents. Developed the backend using FastAPI for managing agent interactions and the frontend using Streamlit for real-time monitoring and user interaction. Implemented a CI/CD pipeline with Jenkins to automate testing and deployment workflows, and deployed the containerized application on AWS ECS and AWS Fargate for scalable, serverless execution.LLM Chatbot Development: Developed and deployed a retrieval-augmented generation (RAG) chatbot using LangChain, OpenAI’s GPT-4, and text-embedding-3-large, enabling helpdesk agents to query internal PDF documents. Used RecursiveCharacterTextSplitter for chunking, stored vectors in ChromaDB, and designed modular chains via LCEL. Improved response speed and accuracy while reducing manual query handling effort.Pricing Optimization (FMCG Client): Designed an optimization engine (COBYLA + regression) to recommend optimal pricing for food products.
