Ex-Head of AI building SaaS MVPs & AI agents, Tel Aviv
A highly scalable, cloud-based real-time auction platform written in Go, which I established and led as R&D Tech Lead at ironSource. Architected for massive scale on AWS and GCP, handling ~50 billion requests and generating $1M+ in daily revenue, with end-to-end observability in Datadog and PagerDuty and performance improvements shipped every week. The same engineering standards go into every backend I build for clients. Enterprise RAG and document-intelligence pipelines I built as Head of AI at Rivery (acquired by Boomi). Multi-stage indexing with AI-native search engines (Perplexity, Tavily) and smart chunking, hybrid retrieval with Cohere reranking and OpenAI embeddings, multi-LLM features across OpenAI, Anthropic Claude and Cohere, and Python evaluation pipelines covered by unit, integration and E2E tests. I can build the same for you: a RAG chatbot or AI search over your own documents, with measured accuracy. A multi-agent AI system I built to run the day-to-day operations of my own SaaS product. Specialized agents handle development, QA, customer support and customer success, so a live product with ~500 users runs with a team of one. Built on OpenAI and Anthropic Claude models with TypeScript, Python and Supabase/Postgres. I build the same kind of agents for clients: support bots, internal assistants, automated QA and workflow automation. WriteinaClick, an AI book-writing platform I designed and built solo, end-to-end. Web and mobile apps, an AI writing assistant (Robin) that suggests edits in the author's own voice, and a multi-agent layer that runs daily operations. ~500 writers in under 6 months, fully organic, with a 34-minute average session and 5 books already published. Stack is React, TypeScript, Supabase/Postgres, GCP, OpenAI and Anthropic Claude.
