Bio

I’m the co-founder and engineering lead at Blaxel, where I’m building the infrastructure layer for AI agents. My background spans cloud systems, microVMs, and distributed compute — from designing next-gen architectures at OVHcloud and developing tooling across large-scale network environments. I’m focused on creating an AI-native platform that makes deploying and scaling agentic applications simple, reliable, and accessible to every developer.
