About
I'm a software engineer based in Belgium. I've been building software professionally since 2018, working mostly in product teams where engineering decisions have a direct impact on the people using the product.
I write about software craftsmanship, career growth, team dynamics, and the lessons that only become obvious after you've shipped the thing. I prefer practical ideas and honest trade-offs over hot takes or recycled advice.
Outside of engineering, I'm into fitness, running, audiobooks, and spending time with my family. I'm also figuring out how to be a good first-time dad.
