Principal Scientist building Large Language Models Applications ¡ Ex-Google, Ex-AppsFlyer, Ex-Microsoft, former CTO, Community Builder
đ Haifa District, Israel
I'm a Principal Scientist II at TII, where I develop Large Language Models Agentic AI, RAG systems, and LLMOps. With 20+ years in software engineering and machine learning, including an ML-focused MSc, I previously headed Data Science at AppsFlyer, a multi-billion-dollar mobile attribution platform.
My work spans the full stack: from building responsive web interfaces to architecting scalable infrastructure, processing data at high scale and managing large infrastructures and highly autonomous teams. I care deeply about automation, continuous deployment, and software craftsmanship. I'm also an active open-source contributor.
Beyond my day job, I co-host Reversim with Ori Lahavâa Hebrew podcast for software developersâand organize Reversim Summit, Israel's largest developer conference, drawing 2,000+ attendees annually.
