Jan 2017 - Mar 2022

Here to design modern training methodologies to match the needs and diversity of 21st century people, based on what neurosciences and my personal experience as a teacher / continuous learner have taught me on how humans learn. My goal is that the learning user experience found at BeCode delivers concrete results, while at the same time be joyful, inspiring and uplifting for the incredible people who join our trainings. The other part of my role as manager is to make sure everyone in the staff feels empowered to have the maximum positive impact on our society. What I do : - Find, hire and onboard the next generation of IT trainers - Structure, update and align BeCode's active learning pedagogy throughout Belgium, using co-creation, design thinking, Agile (I prefer to call it "failing forward" ) - Manage and support trainers in their day-to-day ideas and in their pedagogic upskilling using 1on1s (supervision), honest feedback and encouraging group dynamics of help (intervision) - As part of BeCode's leadership team, I contributed in the growth of an ambitious startup of 11 people into a SME of 45 (and counting...) over 5 cities

At first, an AT Protocol PDS (Personal Data Server) located in my house, this grew into a bigger project to help onboard people to the fast-growing ATmosphere, a decentralized ecosystem of apps and opportunities.

Coach

BLACK RICKERS BASEBALL & SOFTBALL CLUB

Oct 2023 - Apr 2025

I coached and supervised the bi-weekly training of a group of 13 young fellas, aged 12-15, and loved every bit of it. The main challenge I worked on: - turn the group into a team, where solidarity and uplifting each other is key to success despite the diversity of mindsets and skills - improving both hard skills and soft skills. Baseball is a beautiful and demanding sport, especially for young Belgians since they don't see any baseball outside the baseball training hours. That said, it's a great school of life as it foster personal and group ethics.

After‑school tutoring

L'Ilot ASBL

Jan 2024 - Dec 2024

In short: I provided after‑school support and recreational activities with children and teenagers. Why ? I got fed up with living a quiet, safe life while walking past people in deep distress, sleeping directly on the street. I started feeling that I should be a little less part of the problem and a little more part of the solution — at least by trying to support the people who do this work professionally, with some of my time and creativity. I first joined a Christmas celebration there (an absolutely legendary karaoke!) and it was honestly one of the best Christmases of my life because the human warmth was incredible. Now I go every week to help kids and teenagers with schoolwork. The experience is deeply rewarding: I learn a lot from them and, despite their wounds and their challenges, they smile, they show up, and in the end we just have fun together. Their life stories and resilience really humble me. I keep thinking they have so many strengths that our society desperately needs. Every week at L’Îlot, what I see is the raw, unfiltered beauty of humanity. Support L’Îlot : they are really professionals and caring.
