Computer Network / Distributed Systems Engineer
Building large-scale P2P testbeds, blockchain experiments, and research infrastructure
I am a graduate student and engineer working on P2P networks, blockchain systems, and large-scale distributed experimentation. My interests include GossipSub/libp2p analysis, network graph metrics, containerized testbed design, and research infrastructure automation.
