Rockstar🎓
Top SchoolHasan Mahmood is a Senior Engineer based in Austin with 10 years of experience building production-grade backend and networked systems. He currently leads low-level networking and observability work at Datadog, contributing to the system-probe and eBPF-based monitoring that improve connection tracking and performance at scale. His open-source contributions include deep networking work on VMware's vSphere container runtime (vmware/vic) and the widely used Go netlink library, where he implemented route querying and socket handling improvements. Hasan blends backend engineering with DevOps sensibilities—adding test infrastructure and NAT tests—to ensure features are reliable in real deployments. With a Master’s from UT Austin, he brings a strong academic foundation to pragmatic, systems-level problem solving. Colleagues would note his knack for untangling tricky port-layer and network-context bugs that quietly improve platform stability.
