What I'm looking for

I’m looking to build production AI systems that orchestrate tool-using agents, robust RAG, and dependable backend workflows—while designing scalable cloud deployments and monitoring for long-term model reliability.

I’m a Senior AI Agent Orchestration Engineer at Halper AI, building production-ready AI agents with LangChain and LangGraph. I connect LLM reasoning to real workflows using tools, structured actions, validation, retries/fallbacks, and session-aware memory across platforms like Instagram, WhatsApp, and Telegram.

On the RAG side, I designed a dual-index real-estate retrieval setup combining FAISS + BM25 + OCR + CLIP embeddings, then fused building-level and property-specific knowledge for brochure-backed answers. I also wired structured outputs for price, location, amenities, and viewing/booking availability.

Before Halper AI, I served as an AI Engineer at Huddle Systems and led the end-to-end technical roadmap for AI and backend platform scaling. I built scalable microservices, shipped AI-driven recommendation and moderation features, and managed model lifecycle from dataset creation through training, deployment, monitoring, and optimization.

I’ve also led ML work across teams at CybersWave and built agent orchestration systems integrated into web backends at SoulsHub. Earlier roles included converting ML models into production microservices with FastAPI/Docker and building ML for assistive robotics and computer-vision tasks like license plate localization.
