[01] Professional Summary
AI Engineer with hands-on experience building and shipping production LLM systems — multi-agent orchestration, RAG and hybrid retrieval, and real-time voice agents. Designs agentic backends with LangGraph, AgentFlow and MCP/FastMCP, drives structured extraction over large document corpora with Gemini and Vertex AI, and cost-optimises inference by replacing LLM calls with deterministic parsers where accuracy allows.
[02] Experience
AI Software Engineer
Jul 2026 — Present10xScale.ai · Hyderabad
Nirnaya, a legal investigation platform: FastAPI and TaskIQ/Redis pipelines that parse 1,000+ court and registry PDFs into PostgreSQL, deterministic parsers in place of per-document LLM calls, identity resolution with hard vetoes before fuzzy scoring, and a Chrome extension for data collection. Also an AI tutoring platform: low-latency LiveKit voice, adaptive multi-agent routing on AgentFlow, and MCP tools via FastMCP.
AI Intern
Jul 2025 — Dec 202510xScale.ai · Hyderabad
Built a dual-mode medical chatbot with multimodal report analysis (Gemini 2.5 Flash, AgentFlow), a database agent with MCP tools on LangGraph, and a pgvector RAG chatbot over 200+ PDFs.
AI Intern
Apr 2024 — Jun 2024FourKites · Chennai
Built a multi-agent CrewAI workflow converting XML, CSV and Excel inputs into structured JSON, and used Virtuoso for AI-powered application testing.

[05] Selected Projects
Nirnaya — Legal Intelligence
Court and registry records are scattered across portals as unstructured PDFs and HTML. 1,000+ documents from eCourts, Supreme Court, NCLT, DRT, CERSAI and MCA normalised into PostgreSQL, with deterministic parsers cutting LLM cost and latency.
Stack: FastAPI, TaskIQ, Gemini, PostgreSQL, WXT
AI Tutoring Platform
Students needed real-time voice tutoring that adapts to what they are doing. Low-latency WebRTC audio with VAD-based cost control and agents that switch between video Q&A, live coding and study planning.
Stack: LiveKit, Vertex AI, AgentFlow, FastMCP, Qdrant
Database AI Agent
Non-technical users can't query diverse database schemas. Natural-language querying across schemas with a query-understanding preprocessing layer.
Stack: LangGraph, MCP, SQL
RAG Chatbot & Medical Assistant
Answers needed to be grounded in 200+ PDFs and in patient reports and imaging. Semantic retrieval-augmented answering, plus patient/expert modes with database-backed appointment scheduling.
Stack: pgvector, Gemini 2.5 Flash, AgentFlow
