Human or Not (AI21)
**Webby Award Winner!** A Social Turing Game. Chat with someone for two minutes, and try to figure out if it was a fellow human or an AI bot. Think you can tell the difference?

Seasoned software engineer and team lead specializing in GenAI, search, and scalable systems. I build RAG applications, AI agents, and hybrid search solutions using Python, TypeScript, Next.js, and modern frameworks.
As a consultant, I've delivered end-to-end GenAI projects for clients across industries. My background spans ad-tech, finance, and big data with deep expertise in Elasticsearch, OpenSearch, and LLM-powered applications.
Recent wins: Webby Award for "Human or Not" and Google AI Hackathon winner for "Tube Uni."
Available for GenAI consulting, partnerships, public speaking, and private workshops.
I'm excited to announce that I'll be speaking at PyCon Israel 2025 with a talk that demystifies embeddings for software engineers - no ML PhD required!
Join me on July 30th for a comprehensive workshop on building production-ready RAG applications with OpenSearch, covering everything from data preparation to LLM integration.
Learn to build and deploy production-ready Retrieval-Augmented Generation (RAG) systems with hands-on guidance from preprocessing to evaluation.
