He focuses on practical AI integration, exploring how agentic tools and browser-based models change the way software gets built. He frequently speaks on running small LLMs directly in Chrome and using multi-agent workflows to ship full-stack apps. Outside of his day job, he runs the "NG-Heroes" tech meetup and contributes to open-source open projects. When he isn't testing local AI models or managing development teams, Daniel focuses on his family—who humorously crowned him the "Best Developer in the World." ## Upcoming Sessions ### World Congress 2026 North America · September 23, 2026 San José, CA - [From Idea to Production with AI: Agentic Development in Practice](https://www.wearedevelopers.com/events/world-congress-2026-north-america/sessions/1418-from-idea-to) - [Small LLM in your Browser: Huge Opportunities for Web Applications](https://www.wearedevelopers.com/events/world-congress-2026-north-america/sessions/1434-small-llm-in-your) ## Past Sessions ### World Congress 2026 Europe · July 8, 2026 Berlin, Germany - [AI in Your Browser: Exploring Chrome's Built-In LLM](https://www.wearedevelopers.com/videos/100157-ai-in-your-browser-exploring-chrome-s-built-in-llm) · 30 min · 🎥 Watch recording - [Gen-AI on Localhost: Prompt, MCP, Fine-Tune and RAG&Roll](https://www.wearedevelopers.com/events/world-congress-2026-europe/sessions/1658-gen-ai-on-localhost) · 120 min ## Videos - [AI in Your Browser: Exploring Chrome's Built-In LLM](https://www.wearedevelopers.com/videos/100157-ai-in-your-browser-exploring-chrome-s-built-in-llm) · Daniel Ostrovsky ## Links - [X](https://x.com/danduh81) - [LinkedIn](https://www.linkedin.com/in/danduh/) - [Blog](https://medium.com/@danduh) - [GitHub](https://github.com/danduh)
