Hey, I'm Achilleas 👋

Software Engineer @ EUROCONTROL MUAC · BSc Data Science & AI · Freelance via VadioTech 🇳🇱

I work on the COAV (Contrail Avoidance) platform at EUROCONTROL using ground-based imagery and computer vision to detect and track contrails, helping aircraft avoid climate-impacting atmospheric regions. I independently manage the full server infrastructure: detection services, schedulers, and tracking systems running as containerized microservices on Kubernetes.

I'm also the owner of VadioTech, my freelance software and consulting business based in the Netherlands.
