Current Projects 

In 2025, I decided to regroup all my isolated communities, audiences, customers and offerings under a single umbrella: the Knowii Community. Knowii is a community of practice where top-tier professionals get to meet and grow together. Going forward, Knowii will be at the very center of my business. Instead of offering separate/isolated products, I now offer a real transformation to paid members, who get access unlimited access to my entire ecosystem of knowledge (i.e., courses, products, tools, templates, content, ...).

My Story 

Life & Family 

I live in Binche, Belgium, a city with almost a thousand years of traditions.

I have 3 kids, but manage to live a quiet life, free from the frenzy many seem to face with far fewer responsibilities. I don't feel overwhelmed, and I'm (almost) always calm, "zen", even though my life is BUSY. I'm getting married in 2026, with the most wonderful woman on earth (If you know her, you know it's true) ❤️

Childhood 

I was born in 1983, when the Internet and the world was waking up to the World Wide Web. I spent my childhood riding my bike, playing in parks, watching TV, playing videogames, etc.

Around 8, I became addicted to computers and the Web, and never stopped. I played competitive online games for many years: MMOs, FPS such as Counter-Strike, Quake 3, Overwatch, and many others.

As a teenager, I was super shy and introverted. I was not at ease with people, and preferred to write and build websites. I've been writing code for 30+ years, so I know a think or two about that. And I've been writing for almost as long. Writing and IT are my two main passions in life.

I consider myself as kind, generous and humble. I love learning and sharing what I learn. I've explored many areas in my life, some much more deeply than others, but always with the same intensity. Those include: writing, programming, electronics, photography, board games, music theory, guitar, piano, personal development, productivity, personal organization, ...

Given my high level of curiosity and drive to learn, I'm a generalist, not a specialist. Although, when I dive into a new topic I find interesting/valuable, I tend to rapidly develop a deep level of expertise.

Career 

I've been working for ~20 years in the IT industry . Since day one (and actually long before that), I have always been passionate about Software Development, Software Architecture, IT security, Code Quality, the Open Web, Free and Open Source Software (FOSS), IT Infrastructure, ... Professionally, I wore different hats over time: Software Developer, Technical Lead, Software Architect, Solution Architect, Infrastructure Architect, Infrastructure Manager, System Engineer, Team Leader, IT Security Expert, DevSecOps Architect, ...

Recent years 

Back in 2019, I wrote a book called Learn TypeScript by Building Web Applications about the TypeScript programming language and modern Web development frameworks (e.g., React, Angular, Vue, ...). At the time, I was working on a startup project that ended up failing miserably. At the time, I also published many articles about software development on my Website, and started publishing my newsletter. I then started working on a collection of 12 e-books called Dev Concepts which explains a gazillion concepts about IT and Software Development. I published the first two, then decided to put that project on hold because I lacked funding and had to try other things to keep my business alive. I still intend to finish writing those books later on.

In 2020, I decided to pivot my business. I stopped consulting, and focused entirely on Knowledge Management. I started by doing serious research about the ecosystem/market: identifying the experts/enthusiasts, the products & their features, the communities, the main blogs/websites/communities, methods/systems/best practices... That led to the creation of a first product, called the Personal Knowledge Management Library (PKM Library). At first, I wanted to build a Knowledge Management SaaS (hence the research), but since I lacked funding and didn't have enough runway, I instead focused on creating content. I wrote hundreds of articles and newsletters, created communities, a sub-reddit, a Medium publication, a social media account. I also started crossposting my content on different platforms such as LinkedIn, Substack, ... DeveloPassion thus became a media business, and I kept building new things.

Personal Knowledge Management Library
IntroWho is this for? You want to learn how to organize your personal knowledge You wonder how to take smart notes You want to remember more of what you read You want to improve your knowledge management skills If concepts/acronyms such as PKM, SecondBrain, Zettelkasten, Evergreen notes, and Digital Garden make you curious, then you’ve come to the right place!It is well-known that our memories are not reliable. To store and organize knowledge bases, we need digital solutions to help us. But that’s not enough. To keep things manageable over time as our knowledge base scales, we need clear techniques and methodologies.What is this?I’ve been passionate about information, knowledge management, and PKM for more than 20 years. As a knowledge worker, author, blogger, and entrepreneur, I needed solutions to store and organize an enormous amount of information.Over the years, I’ve explored, used, and advocated many different tools: old-school wikis (e.g., MediaWiki, TiddlyWiki, DokuWiki, Confluence), note-taking solutions such as Evernote, Google Keep, Microsoft OneNote, Okular, Zim, and many more.Recently, the Personal Knowledge Management space has evolved a lot with the rise of tools such as Notion, Obsidian, Roam Research, LogSeq, and others. Those have drastically changed the knowledge management landscape and brought us the opportunity to manage knowledge much more efficiently, and to truly create ourselves a second brain, or digital garden.During most of 2021, I’ve done extensive research and curated a ton of information and links about the Personal Knowledge Management space. I’ve now regrouped all of this inside of a Notion space.It is now a solid database of the best resources you can find on the subject around the InternetEach and every week I add new resources to this Notion space: articles, blogs, books, courses, tools, videos, etc. This includes the content that I publish myself on the subject and my weekly newsletter.Note that this product is included in the Knowii offer.What you will getHere, you can buy lifetime access to my Notion space, and get regular updates; either for you personally, or for your team.What’s included? A list of 290+ tools Links to 350+ articles Links to 145+ videos A list of 90+ books about learning, thinking, writing, note-taking, journaling, neuroscience, psychology, stoicism, etc Links to 225+ sites & blogs A list of 75+ Youtube channels A list of 90+ courses A list of 90+ newsletters A list of 40+ podcasts A list of podcast episodes A list of 70+ communities and forums A list of ~2K PKM leaders, influencers, and enthusiasts A list of 50+ starter kits and templates A list of 100+ Twitter hashtags to follow A list of 80+ topics and links to relevant articles, books, videos, etc And more! I will keep adding to the Notion space, and I’ll continue contributing information for the whole community.You’ll also get lifetime access to the Personal Knowledge Management community for support and knowledge sharing.Testimonials

In 2022, I created the Obsidian Starter Kit, a 1:1 copy of my own system in Obsidian. I knew it worked since I was using it everyday. It was stable, and scaled really well. I sold hundreds of copies and kept improving it since then. I still maintain it, and intend to continue making it evolve. Meanwhile, my Knowledge Management practice became more and more mature, to the point I now consider myself a domain expert. I later created the Obsidian Starter Course, focusing on Obsidian and knowledge management best practices I learned from experience.

In 2024 I've also built a number of Obsidian plugins and templates to scratch my own itch and further improve my practice:

In 2024, I started working on the Knowledge Management for Beginners course. I released it in early 2025. That course covers everything I know and believe about Knowledge Management. It also goes wide and deep, and covers both theory and practice, applying design & systems thinking approaches to help people build their own system (rather than just using/tweaking a tool without proper system design).

In 2025, I launched a first product about AI, the AI Ghostwriter Guide. It's a guide I wrote based on the approach I used and refined to create my own AI Ghostwriter, helping me write articles, newsletters, sales copy, etc.

Build Your AI Ghostwriter: The Complete Guide to Creating an AI Assistant That Writes Like You
What is this?Transform any AI into your personal ghostwriter that writes with your exact voice, style, and expertise using this proven step-by-step system.Who This Is For✅ Perfect if you: Create content regularly (articles, essays, newsletters, social media posts, etc) Want to scale your content using AI without losing your unique voice Spend too much time editing AI slop-generated content Have products or services to promote through content Want to build a sustainable content creation system ❌ Not right if you: Never create content or have no interest in writing Prefer to write everything manually without AI assistance Don’t have existing writing samples to analyze Are looking for a “magic button” solution without any setup Stop Using AI Like a Dummy. Start Training ItYou’ve tried them all: ChatGPT. Claude. Gemini. But every time, you feel the same frustration: “This doesn’t sound like me at all.“The AI gives you generic text, content that could apply to anyone. You spend more time editing than you would writing from scratch. I’ve been there as well, but that was a long time ago!Here’s the problem: You’re using AI like everyone else—throwing random prompts at it and hoping for magic to happen. But that’s not the way it works!The solution? You have to TEACH AI to write like YOU.What If AI Could Capture Your Exact Voice?Imagine opening your AI assistant and getting content that: ✅ Sounds like YOU ✅ Uses your signature sentences and personality quirks ✅ Understands you and your unique perspective ✅ Knows your content strategy and helps you create highly relevant content for your target audiences ✅ Knows your business, your brand, your products and services, your audience, etc ✅ Creates content across all your formats (articles, essays, newsletters, social media posts, scripts, ...) ✅ Evolves over time Sounds too good to be true? Well this isn’t fantasy. It’s exactly what I’ve built for myself. And now, I’m showing you how to do the same.The System You NeedAt this point, my AI Ghostwriter has helped me write hundreds of pieces of content: notes, articles, newsletters, podcasts, course scripts, emails, letters, etc.I’ve spent months perfecting this system and approach. I’m relying on it daily, and thus I know from experience that it works flawlessly. The cool part is that I’ve documented it all along the way, and thus I can teach you how to create the same for yourself.This isn’t about better prompts (though you’ll get those too). This is about creating an AI Ghostwriter that understands you and your needs.Why This WorksMost people make these mistakes: ❌ Using generic prompts hoping to get unique content ❌ Starting over with new prompts for every piece of content ❌ Settling for “good enough” content that needs heavy editing ❌ Abandoning AI because “it doesn’t work” My system fixes all of this by: ✅ Creating a comprehensive description of your personality, writing style, rules, content strategy, content types, and more! ✅ Training AI to adapt to your style, not the other way around ✅ Building a system that delivers high quality results and improves over time ✅ Establishing consistency across all content types What’s IncludedYou’ll get the complete step-by-step guide you can follow to create your own AI Ghostwriter, including: Clear explanations Many AI prompts you can use to help you create the documents you need Document templates Advanced techniques for power users 💡 Bonus Resources Private community access for questions, updates and knowledge sharing Real examples taken from my own implementation Frequently Asked QuestionsQ: Do I need deep technical skills to implement this? A: No. There are advanced options for power users, but the core system works with simple copy-paste/upload on any AI platform.Q: Which AI platforms does this work with? A: ChatGPT, Claude, Gemini, DeepSeek, NotebookLM, ... Basically, any AI that accepts custom instructions and/or file uploads.Q: How long does it take to set up? A: Basic setup takes 2-3 hours. Advanced implementation with Model Context Protocol (MCP) can take a weekend, but the time savings compound quickly.Q: Will this work for my niche/industry? A: Yes. The system analyzes YOUR writing samples, so it works regardless of your topic, industry, or content type.Q: What if I don’t have enough writing samples? A: Start with what you have. You can still add more later. It’s not a showstopper.Stop settling for generic AI responses. Start creating content that sounds like YOU.
