Bridging first-principles AI reasoning with robust software engineering.
I'm a Computer Science student at CBIT Hyderabad focusing on Agentic AI, RAG architectures, and real-time intelligent systems. I believe in understanding how LLMs reason without hiding behind bloated framework abstractions.
01
First-Principles Agent Loops.Understanding prompt construction, tool-invocation dispatch, and state memory from scratch.
02
Hybrid Retrieval Over Naive Vector Search.Combining BM25 keyword matching with dense embeddings and FlashRank cross-encoder reranking to eliminate hallucinations.

01
AI Agent from Scratch (No Frameworks)
Custom AI agent built in pure Python without LangChain or agent frameworks, using the Sarvam AI API for autonomous reasoning.
Implemented the full agent loop manually: prompt construction, response parsing, and tool-invocation logic with live web search capability.
Demonstrated core agentic concepts (reasoning, tool-calling, action-taking) from first principles without prebuilt framework abstractions.
End-to-end Financial RAG pipeline to ingest, index, and query complex financial documents with hybrid retrieval and reranking.
Built with LangChain, ChromaDB vector store, Sentence Transformers embeddings, and the Groq API for high-speed inference.
Designed a multi-stage hybrid retrieval layer combining semantic dense search, BM25 sparse retrieval, and FlashRank cross-encoder reranking to eliminate hallucinations.
Data-driven technical interview platform generating role-specific questions with adaptive follow-up logic and speech signal evaluation.
Generates and evaluates 500+ role-specific questions with dynamic context-aware follow-up questioning.
Built a speech/voice processing pipeline extracting acoustic features (pitch variance, pause distribution, confidence) to generate automated feedback reports.
Added real-time acoustic pitch variance and pause feature extraction pipeline.
