What I'm looking for

I’m looking for an AI-focused role where I can build RAG and multi-agent systems, ship reliable APIs, and improve retrieval quality with strong evaluation—while growing alongside experienced engineers.

I’m a B.Tech student in Artificial Intelligence at National Institute of Technology Rourkela (CGPA: 8.21/10, expected 2024–2028). I focus on turning retrieval-augmented and agent-based ideas into production-style services using Python, FastAPI, and robust database-backed workflows.

In my Multi-Agent Customer Support Platform, I designed a layered LangGraph system with 8 specialized agents, durable state management, and Human-in-the-Loop approval, exposing 27 FastAPI REST APIs backed by PostgreSQL, pgvector, and SQLAlchemy. I also built a Self-Corrective RAG framework with recovery strategies (like query rewriting and web-search fallback), and benchmarked it against Vanilla RAG—improving Faithfulness (71.2%→94.5%) and reducing hallucinations by 88.7%.

Work history, roles, and key accomplishments

Self-Corrective RAG

GitHub

Jul 2026 - Present (0 months)

Architected a Self-Corrective RAG framework with recovery strategies (query rewriting, memory, web-search fallback, knowledge-gap detection, and retry workflows) to improve retrieval quality. Benchmarked on 100 evaluation queries, improving Faithfulness, Answer Relevancy, and Context Recall while reducing hallucinations.

Multi-Agent Customer Support Platform

GitHub

Jun 2026 - Present (1 month)

Built a layered LangGraph-based multi-agent AI support platform with durable state management and Human-in-the-Loop approval workflows. Implemented multilingual RAG ticket processing, developed 27 FastAPI REST APIs, and deployed the platform using Docker on Hugging Face Spaces.
