## Education

## Involvement

### Volunteering
- BLACK RICKERS BASEBALL & SOFTBALL CLUB (Oct 2023 - Apr 2025)
  Coach
  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.
- L'Ilot ASBL (Jan 2024 - Dec 2024)
  After‑school tutoring
  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.
