What I'm looking for

I’m looking for a backend/cloud-native security role where I can build high-performance services, improve CI/CD reliability, and strengthen observability and incident readiness while shipping multi-cloud features end to end.

I’m a Backend Development Engineer building cloud-native security services and infrastructure features across the container lifecycle—from images and orchestration down to runtimes. I’ve developed core backend systems, including eBPF-based host security probes, distributed image scanning engines, and network microsegmentation controls with Kubernetes-native integrations.

I bring a strong engineering mindset: I design for observability and resilience, optimize storage/query performance for large-scale assets, and improve pipeline reliability through modular CI architecture. In my recent work on China Mobile Cloud and Arksec’s platform, I’ve led multi-cloud integrations, built high-concurrency task scheduling, and delivered features that reduce operational risk while improving security coverage.
