Summary
🤩
Rockstar🎓
Top SchoolCheng-zhen Yang is a backend-focused software engineer with nine years of experience designing high-performance systems, particularly in Go, gRPC, and observability tooling. He has driven production improvements at companies from startups to large platforms—uplifting observability with OpenTelemetry at mx51 and building protocol-driven SDKs and integration tests for decentralized systems at Sylo. Cheng-zhen combines a pragmatic engineering mindset with a knack for automation, having saved 100+ development hours by building in-house tooling and streamlined S3/streaming pipelines early in his career. He’s recently worked at TikTok and is currently affiliated with Google, bringing experience in multi-tenant architectures, RBAC/SSO integrations, and scalable file processing. Comfortable across cloud-native stacks (Kubernetes, Terraform, AWS) and data stores, he also surfaces non-obvious wins like a 10x GraphQL introspection speedup via targeted caching. Based in Sydney and active in practical R&D, he blends systems-level thinking with hands-on delivery in observability and backend platforms.
