At RBC, he built K8s CronJobs for Terraform drift detection. The homelab runs 20+ services with 99.2% uptime, managed via ArgoCD GitOps. - -**Q**: Tell me about the LLM setup. -**A**: The homelab runs vLLM serving Qwen3-32B with INT4 quantization on GPU. It's orchestrated by KServe with a custom Go API gateway. This setup achieved 60% latency reduction. Also runs Ollama for smaller models and TEI for embeddings. - -**Q**: What did you do at AWS? -**A**: Rock owned Distributed-Map for Step Functions—from design doc to production across 57+ regions. Key achievements: sub-100ms P99, 20x burst handling, checkpoint recovery for failed workflows. He also owned oncall and built the observability dashboards. - ---- - -## Contact & Links - -- **Portfolio**: portfolio.riotpiao.com -- **GitHub**: github.com/rockliang -- **LinkedIn**: linkedin.com/in/rockliang -- **Email**: locartrock@gmail.com
