Talks
I started to give talks in technical events many years ago and continue to do so as a DevRel today. Here is a glimpse of my topics.
Image Generation - Enhancing QR Codes in the Age of GenAI
Discover how GenAI is revolutionizing the personalization of QR Codes. This presentation highlights the technical foundations of QR Codes and demonstrates, through practical examples, how tools like ControlNets enable the creation of unique QR Codes that blend functionality and aesthetics — all executed locally on a PC. Immerse yourself in a future where every scan becomes an engaging visual experience.

Image Generation - Mastering Image Generation with Stable Diffusion
Discover how to generate precise, diverse, and inclusive images using Stable Diffusion and ComfyUI. This talk showcases how to control poses, styles, and character consistency for use cases like yoga pose visualization. Learn to master text-to-image and image-to-image workflows, leverage LoRA for lightweight customization, and create visually rich, inclusive image libraries. With live demos and actionable insights, this session inspires your next creative AI project.

Agentic AI - The Future Beyond LLMs: Exploring Agentic AI
What exactly are AI Agents, and how do they operate? How do they compare to and interact with LLMs and functionalities such as function calling, chain-of-thought processing, assistants, tools, or actions? In this talk, I delve into the unique features of Agentic AI, including perception, state estimation, goal setting, planning, and action selection & execution. We will define various levels of Agentic AI and form a map to help navigate this emerging landscape. By categorizing current agent-based or agent-related solutions with practical examples, we'll provide an overview of the current state of Agentic AI.

Generative AI - Chat with your Documents: Discover the magic of RAG with and without OpenAI
This talk explores the revolutionary concept of Retrieval-Augmented Generation (RAG) in Large Language Models. Participants gain practical insights into implementing RAG using OpenAI and various open-source alternatives, including hands-on demonstrations with Node.js and Jupyter Notebook. Attendees learn about customizing LLMs, mastering embeddings, and discovering innovative tools like Flowise, ANythingLLM, RAGFlow, Dify and Hugging Face models. The talk concludes with a look at the future of RAG and its implications for developers and businesses, highlighting the dynamic advancements from major tech players and the open-source community.

Generative AI - From OpenAI to Opensource AI: Navigating Between Commercial Ownership and Collaborative Openness
This presentation explores the evolution of generative AI, highlighting the trajectories of various models such as GPT-4, and examining the dynamics between commercial interests and the ethics of open collaboration. We offer an in-depth analysis of the levels of openness of different language models, assessing various components and aspects, and exploring how the (de)centralization of computing power and technology could shape the future of AI research and development. Additionally, we explore concrete examples like LLaMA and its descendants, as well as other open and collaborative projects, which illustrate the diversity and creativity in the field, while navigating the complex waters of intellectual property and licensing.

Architecture - The hitchhiker's guide to software architecture and design (with my colleague Alexandre Touret)
Designing a new platform is always tricky to set up. How to start? What is the best strategy to adopt while designing a platform? What kind of architecture should we deploy: event streaming, orchestration, or choreography? For a brand-new platform: "Donut @ Home", we will proceed a live architecture study. After analyzing the customer needs, brainstorming, and exchanging our ideas, we will choose among all the potential solutions the least worst option. You will be asked to validate our design and the different implementation examples. At the end of this talk, you will have tips and tricks for thinking about it and starting working on architecture studies in complete peace of mind.

Decentralization - Towards a Redecentralization of the Internet: Exploring Current Technologies and Initiatives
The Web and Internet are constantly evolving, and a crucial question arises: how can we (re)decentralize these platforms to ensure an open, resilient and privacy-respecting Internet? In this presentation, we will explore a comprehensive overview of the various current initiatives and technologies contributing to this (re)decentralization. We will delve into the exciting world of Web3 with its concepts of blockchain, dApps, consensus, and DLT. We will also discover the promises of Web 3.0, including projects such as Solid and the semantic web. We will then explore the Fediverse, an ecosystem of decentralized social networks, as well as Holochain, a peer-to-peer application development technology.

Web3 - Understand the architecture of Web3
Web3, blockchain, cryptocurrencies, tokens, wallet, NFT, smart contract, dApp, DAO… It’s about taking a step back from the buzzwords and speculative bubbles to better understand what is happening in the background: re-decentralization of the Internet! This presentation is the map that I would have liked to have had at the start of my exploration of the enormous ecosystem that is the decentralized Internet (or Web3 as it is sometimes incorrectly called).
