About Dany

Full stack developer .NET / React with an obsession for offensive security (Pentesting)

I build end-to-end products that solve real business problems, and I think like an attacker while doing it. eJPT certified and trained at Maldev Academy, I spend as much time shipping applications as figuring out how to break them.
That dual perspective changes everything: validation, auth and secret management become critical features rather than checklist items, and threat modeling happens before the first commit, not after the first incident.

I also embed AI/LLM capabilities into business apps, notably through Semantic Kernel / Microsoft Agent Framework

If you need someone who can build the product AND make sure it survives production, let's talk.

P.S. As an IT enthusiast, I collect tech disasters. If you have some "masterpieces" for my Gallery of Horrors, feel free to send them over! Check it out here: dany-vanmuylder.com/gallery
