Current Quest: Building reliable, production-grade agentic AI systems
Side Quests: 17+ hackathons cleared | 5th place @ Hack-Ula
| Build | Materials | What it does |
|---|---|---|
| 🗡️ Interroga AI | Python, FastAPI, LangGraph, FAISS, Sarvam AI | LangGraph RAG + GraphRAG agent that generates cases with hidden suspect/truth graphs, voice agents at 2.1ms latency, and a Judge Agent to evaluate accusations |
| 🛡️ HoneyMind AI (live) | XGBoost, Reinforcement Learning, FastAPI | Trained a fraud-detection model, extracted it via Knockoff Nets/JBDA attacks (~99% surrogate accuracy), then built an RL defense gateway that drops extraction accuracy to ~50% |
| ⛈️ Namma Weather (live) | XGBoost, LightGBM, TensorFlow, Optuna | Multi-agent hyperlocal weather forecasting for Bengaluru — gradient-boosting ensemble fused with physics-constrained agents and a MobileNetV2 cloud classifier |
| 🦆 Rubber Duck AI | LangGraph, Qdrant, Vapi | Dual-agent dev assistant: a voice agent + a dashboard agent rendering contextual flowcharts/diagrams from your own repos via RAG |
| 🧠 MiniGPT | Python, NumPy | GPT-style decoder-only Transformer built from scratch in raw NumPy — attention, backprop, and Adam optimizer included |
