Find the right talk for your audience
Practical browser AI, explained clearly and without the hype.
Built for curious audiences
I'm Nico, an open-source machine learning engineer at Hugging Face, a maintainer of Transformers.js, and a Google Developer Expert in AI and Web Technologies. After more than a decade of building for the web, I now explore what happens when modern AI meets the browser.
I've spoken at developer conferences across Europe since 2018. I match the technical depth to the room, explain the trade-offs without the hype, and leave people with ideas they can actually try.

“I’m AFK for a Bit”: Letting an AI Agent Run Wild on WebGPU Kernels
A case study on letting an AI coding agent autonomously write and optimize custom WebGPU kernels for in browser inference, achieving multiple-x speedups for all kinds of ML models. The core insight: autonomous optimization becomes trustworthy not through better prompting, but through project structure. Bounded edit surfaces, independent correctness oracles, and noise-resistant benchmarking.
Engineers already working with agentic coding tools (Claude Code, Opencode, etc.) who want advanced patterns for making autonomous agents safe and productive on hard, low-level problems. No WebGPU or ML background required.
It Depends: the final and honest take on client-side AI
A hype-free look at when client-side AI actually makes sense in production. Beyond flashy LLM demos, the talk focuses on small, reliable models (VAD, background removal, classification), the client-vs-server trade-offs, and a decision framework for where AI workloads should run. Plus a glimpse at what's coming (kernel optimizations, cross-origin storage).
Web developers and tech leads who are curious about AI in the browser but need a realistic, production-oriented framework for deciding what belongs client-side, server-side, or hybrid.
Look ma, no hands! Multimodal AI-Agents in the browser
How to build multimodal AI agents (voice, vision, context, tool calling, RAG) running entirely in the browser via WebGPU and WebAssembly. Fully offline, no cloud provider, privacy-preserving by default, with concrete demos showing what on-device agents can do beyond chatbots.
Developers and decision-makers exploring what modern on-device AI can do beyond chatbots, who want inspiring but concrete demos of multimodal agents built with standard web technologies.
Let’s build K.I.T.T. with JavaScript
Recreating Knight Rider's talking car in the browser: an offline AI agent with personality, memory (RAG), and autonomous actions (function calling), connected to real hardware via WebBluetooth. An entertaining vehicle (literally) for teaching AI agent patterns with JavaScript and on-device LLMs.
Developers of any AI experience level who learn best through playful, hands-on storytelling, especially those curious about connecting browser-based AI agents to real hardware.
What organisers said
Nico’s live demos were a real highlight of code.talks: ambitious, engaging, and executed flawlessly. He made complex ideas tangible and kept the audience hooked throughout.
Nico is the full package 😂🔥 Crazy smart, an amazing speaker, and somehow still one of the most down-to-earth people you’ll meet. Honestly, one of the smartest people I’ve ever seen speaking—and just a genuinely great human on top of it. We need more speakers like Nico!
One of our absolute favorites — because apparently live demos are only scary for the rest of us. 😎
We've had Nico on our podcast multiple times, so we knew what we were getting: prepared, responsive, no chasing required, and a genuinely good storyteller. Unsurprisingly, he won our conference's audience award for best speaker. We invited him back immediately.
It was a pleasure to have Nico as part of the DevTalks Romania 2026 lineup. Our collaboration was fantastic. Nico is professional, engaging, and genuinely passionate about sharing his knowledge. We’d be happy to have him back anytime.
