Chris Tarazi
Software Engineer at Isovalent
United States
Summary
🤩
RockstarChris Tarazi is a software engineer with 11 years of experience specializing in eBPF, Kubernetes, and low-level cloud networking. At Isovalent he contributes to Cilium, focusing on ENI, BGP, IPsec policy configuration, and BPF tunnel/forwarding logic to make cloud networking more secure and observable. His open-source work on the widely used cilium/ebpf Go library includes adding mmapable and inner map support, refactoring batch APIs with a safer BatchCursor abstraction, and real-world tests for chunked lookups. Comfortable operating at the kernel-user boundary, he combines systems-level rigor with practical engineering for production cloud environments. A useful but less obvious strength is his ability to translate complex kernel primitives into ergonomic Go APIs that reduce developer mistakes.

ebpf-go is a pure-Go library to read, modify and load eBPF programs and attach them to various hooks in the Linux kernel.
Role in this project:Back-end Developer
Back-end DeveloperContributions:4 reviews, 2 commits, 5 PRs in 4 days
Contributions summary:Chris primarily contributed to the `ebpf-go` library, adding feature tests for new eBPF functionalities like mmapable and inner maps. They modified core files related to map creation and system calls, integrating the new features. Their work also included refactoring the batch API, introducing a `BatchCursor` abstraction to simplify usage and enhance its safety. Additionally, the user added a unit test to demonstrate chunking capabilities within the batch lookup API.
