## Core Engineering Specializations
- Autonomous Multi-Agent Systems: Stateful, cycle-tolerant multi-agent orchestration with LangGraph, human-in-the-loop approval, and deterministic tool execution.
- Production RAG Architectures: Hybrid retrieval (dense semantic vectors + sparse BM25), reciprocal rank fusion (RRF), adversarial fact-auditing, and citation grounding.
- Digital Image Forensics: Error Level Analysis (ELA), sub-pixel tampering detection, and image manipulation auditing.
- Real-Time Voice AI: Full-duplex conversational voice agents built with LiveKit Agents SDK, Silero VAD, Deepgram STT, Groq LLM inference, and ElevenLabs TTS.
- Document AI: Embedded PDF intelligence, spatial layout analysis with PyMuPDF, OCR with Tesseract, and local LLM acceleration.
