About

I build AI agents, RAG pipelines, and LLM-powered applications from architecture through deployment. My flagship project, AgentifyAI (www.AgentifyAI.in), is a multi-agent learning platform built with LangChain, tool calling, Pydantic, and JSON-first prompting. I designed orchestrator-led routing, structured response validation, and modular coach, planner, and executor roles to improve reliability and observability. Selected work: - RAG systems with FAISS, Sentence Transformers, and contextual tutoring - Local LLM applications using Phi-3 and Ollama - NLP classification with TF-IDF and Multinomial Naive Bayes, achieving about 93% test accuracy - Full-stack AI applications using FastAPI, Next.js, Streamlit, Vercel, and Netlify - MCP integrations and agentic workflows Professionally, I am a Data Specialist at The D. E. Shaw Group in Hyderabad, where I build Power BI dashboards, automate reporting workflows, validate large-scale datasets, and support data quality and governance initiatives. Core stack: Python, LangChain, LangGraph, RAG, FAISS, FastAPI, Pydantic, MCP, Hugging Face, Groq, Scikit-learn, Pandas, and Power BI. Microsoft Azure AI Fundamentals (AI-900) certified.
