01 — About

A vector space of curiosity, systems thinking, and shipped code.

I'm an AI/ML undergraduate at VVIT specializing in production-ready generative AI applications — from data ingestion and embeddings to full RAG pipelines and agentic orchestration.

My work spans LangChain and LangGraph for multi-step reasoning, vector databases like Qdrant, FAISS and Chroma for retrieval, and FastAPI backends that hold it all together — with a strong foundation in DSA, machine learning, and backend systems engineering.

One core, many connections — like a neuron firing across a stack.

The center is the engineer; every dendrite is a tool that carries a signal into production.

03 — Experience

Where the systems got real.

Internship
CDAC — Software Engineering Intern

Designed and implemented efficient telecom traffic data storage using Berkeley DB, optimizing query performance for large-scale network topology and traffic matrices. Built structured retrieval mechanisms improving data access efficiency for enterprise-scale datasets.

Community
TEDx VVIT — Event Operations Coordinator

Coordinated with speakers and managed on-ground logistics, ensuring smooth execution of the event and strong audience engagement, working within a cross-functional team.

Projects, from retrieval to real-time.

01 / Currently Working

Enterprise-grade RAG system built on LangGraph — agentic workflows with multi-step reasoning, conversation memory, and history-aware query planning. NeMo Guardrails block off-topic queries, prompt injection and jailbreak attempts. Portkey Gateway auto-fails over across Groq API keys for high availability. Retrieval runs on Qdrant Cloud with 3072-dim Gemini embeddings and FlashRank re-ranking.
