Tech Stack: LangChain, Groq (openai/gpt-oss-20b), FAISS, HuggingFace, and Streamlit.

* Engineered an end-to-end RAG system using LangChain and a vector database to automate document Q&A for complex shipping manifests and policy PDFs.

* Boosted retrieval precision by implementing MMR (Maximal Marginal Relevance) and re-ranking techniques to solve multi-document context issues.

* Developed a custom data pipeline to clean, chunk, and process raw logistics data, ensuring high-quality semantic search across the entire knowledge base.

* Reduced internal support tickets by 40% in the first month by deploying the AI tool and iterating based on support team feedback.

* Led full-cycle deployment from initial vector DB setup to production, including UI refinements and performance monitoring.

* Optimized system accuracy through internal trials, replacing basic search flows with advanc

* Engineered a Natural Language-to-SQL (NL2SQL) pipeline that allowed non-technical users to query 50+ relational tables using plain English, reducing dependency on the data engineering team for ad-hoc reports by 65%.

* Architected a Multi-Agent system using LangGraph that autonomously selects relevant schemas through Dynamic Schema Linking, resulting in a 92% accuracy rate on complex queries involving multi-table joins and sub-queries.

* Implemented a Self-Correction Loop using ReAct (Reason + Act) logic, which decreased SQL execution errors by 40% by allowing the agent to "self-heal" and rewrite queries based on database error logs.

* Integrated an Agentic Visualization Layer using Python REPL and Plotly, enabling the system to not just fetch data but also generate interactive trend charts and distribution plots with a Time-to-Insight of < 5 seconds.

* Hardened system security by implementing a &quo
