Summary

Senior🎓
Top SchoolGuo L is a Senior Site Reliability Engineer based in Singapore with 11 years of experience building and operating resilient infrastructure across cloud, networking, and security domains. He has driven SRE initiatives at F5 and Tencent, automating deployments, troubleshooting complex Linux/DPDK load balancers, and writing protocol dissectors and integration scripts to streamline operations. His background spans system consulting and technical leadership roles where he designed virtualization, monitoring, and HA solutions, often using bespoke automation (Python, Bash, Ansible) to replace manual processes. Comfortable across Windows and Linux stacks, he pairs low-level packet troubleshooting (Wireshark/tcpdump) with cloud-native practices like Kubernetes and CD-driven upgrades. Notably, he has implemented pragmatic migrations (P2V, offline cloning) and custom tooling to preserve service availability during large-scale changes, reflecting a bias for measurable operational reliability.
