• Cloud Modernization: Orchestrated the end-to-end migration of 20+ legacy EC2 services to AWS EKS using Terraform. By standardizing the runtime environment, reclaimed 30+ engineering hours/month previously spent on manual OS patching and redirected them to CI/CD automation, significantly lowering the Total Cost of Ownership (TCO).
• CI/CD & Release Engineering: Architected automated pipelines via AWS CodeBuild and Jenkins, reducing deployment cycle time by 80% (from ~30min to ~5min). Implemented Canary Deployment via Argo Rollouts and Gateway API to minimize deployment risk through phased traffic shifting.
• SLO Framework: Designed and established an SLO-based reliability framework for a financial trading platform with 150K+ database QPS at peak, defining SLIs (latency P99, error rate, throughput) and SLOs across critical domains — order matching, deposit/withdrawal processing, and user authentication. Formulated error budget policies and multi-window burn rate alerting strategy, aligning engineering and product teams on reliability-velocity tradeoffs.
• AI-Augmented Operations: Engineered AI operational guardrails — including pre-execution hooks for kubectl/Helm and declarative policy-as-code — to safely delegate bulk infrastructure changes across 4 EKS environments. Enabled a single engineer to audit and propagate config changes across 80+ shell scripts and Terraform modules via human-in-the-loop workflows, while leveraging AI-assisted log triage to accelerate multi-cluster incident root cause analysis.

SRE / DevOps Lead - Mending Technology (眾⿍科技)

(2023-12 - 2025-07)

• Service Modernization: Orchestrated the containerization of 20+ services and transitioned to microservices via GitLab CI/CD, reducing deployment time from 1.25hr to 15min and sustaining 8,000+ RPS during DDoS attacks with CloudFlare and HPA auto-scaling.
• Security Incident Response: Defended against targeted APT campaigns including DDoS attacks and trojan infiltration, implementing MDR (24/7), CloudFlare DDoS mitigation, network segmentation (EKS NetworkPolicy), and cloud-native secrets management (AWS KMS, Secrets Manager) to secure the platform's cryptographic dependencies.
• Reliability: Established comprehensive monitoring with Prometheus and Grafana, achieving 99.9% service availability and reducing MTTR by 97% (from ~3hr to ~5min) through automated database failover and self-healing infrastructure.

(2017-11 - 2023-11)

• Security Automation & Research: Developed an automated security analysis platform to streamline threat detection, utilizing traffic mirroring and analysis to enhance incident response workflows.
• Cloud Security Compliance: Led the AWS migration and containerization of project products, successfully achieving the AWS Security Competency Partner certification through rigorous security architecture validation.
• Infrastructure Standardization: Established core DevSecOps and Cloud-Native architectures, providing standardized monitoring and CI/CD solutions that unified delivery across various departmental projects.
