About Me

AI/ML Engineer (final-year B.Tech, AI & Data Engineering @ LPU), currently an AI Engineering Intern working on LLM Systems & Applied GenAI — building production-grade agentic pipelines with LangGraph, open-weight LLMs, and full observability.

  • Building EquityFlow, a multi-agent equity research system (LangGraph, Llama-3.1-8B, Tavily, yfinance, ChromaDB, FastAPI, LangFuse).
  • Author of AutonoML v2.3.0, a multi-agent AI platform — Planner (DAG), parallel Research, ReAct Execution, hybrid LLM + programmatic Evaluation, two-tier memory, 386 tests; SmartRouter cuts latency from ~45s → ~2s on direct queries.
  • Previously built data/AI pipelines at Futurense Technologies.
  • Shipped AIOps RCA (XGBoost + SHAP + FastAPI + Docker) and a serverless Model Arbitration Engine on AWS (87ms avg latency across sklearn / XGBoost / Bedrock).
  • Interests: LLM orchestration & agents, RAG evaluation, MLOps/AIOps, GPU-poor-friendly open-source model engineering.

Experience



  • Building multi-agent LLM systems (research, writer, and critic agents) with real LLM calls, web research, financial data tooling, and persistent memory.
  • Instrumenting pipelines end-to-end with LangFuse tracing and eval hooks for reproducible agent behaviour.


  • Integrated and cleaned 5+ MBA admissions datasets using Python (Pandas), performing data preprocessing and exploratory data analysis to uncover campaign and enrollment insights.
  • Developed a multi-page Power BI dashboard to visualize KPIs, marketing funnel performance, applicant analytics, and campaign ROI for data-driven decision-making.
