I’m David Park, DevOps & Cloud Architect at Kurai. I specialize in building infrastructure that’s reliable, scalable, and cost-effective. My background at Uber and AWS has given me deep expertise in cloud architecture, Kubernetes, and infrastructure automation.
Infrastructure at Scale
At Uber, I led infrastructure migrations that served millions of requests per second with 99.99% uptime. At AWS, I worked as a Solutions Architect helping enterprise customers design cloud architectures that saved them millions in infrastructure costs.
I believe that great infrastructure is invisible—it just works. My job is to make sure your backend and AI systems run smoothly, 24/7/365.
My Expertise
Cloud Architecture:
- Multi-cloud strategies (AWS, GCP, Azure)
- Serverless architectures (Lambda, Cloud Functions)
- Hybrid cloud (on-prem + cloud)
- Cost optimization (rightsizing, reserved instances, spot)
Container Orchestration:
- Production Kubernetes (EKS, GKE, AKS)
- Docker containerization best practices
- Service mesh (Istio, AWS App Mesh)
- Helm charts and ArgoCD for GitOps
Infrastructure as Code:
- Terraform for multi-cloud provisioning
- CloudFormation for AWS-native resources
- Ansible for configuration management
- Pulumi for modern IaC
CI/CD & Automation:
- GitHub Actions, GitLab CI, Jenkins pipelines
- Automated testing and deployment
- Blue-green and canary deployments
- Infrastructure testing (Terratest, Kitchen)
Monitoring & Reliability:
- Prometheus + Grafana dashboards
- ELK stack for log aggregation
- Distributed tracing (Jaeger, X-Ray)
- SRE practices (SLIs, SLOs, error budgets)
Production Infrastructure
Recent infrastructure projects I’ve delivered:
- Multi-region setup: AWS active-active deployment across 3 regions
- Kubernetes migration: Lift-and-shift of monolithic app to microservices on K8s
- Cost optimization: Reduced AWS bill by 45% for SaaS client
- Disaster recovery: Implemented RTO of 15 minutes, RPO of 5 minutes
Reliability Engineering
I follow Site Reliability Engineering (SRE) principles:
- Measure everything: Metrics, logs, and traces
- Automate relentlessly: Manual tasks are errors waiting to happen
- Design for failure: Everything fails, design accordingly
- Blameless postmortems: Learn from incidents without blame
Security & Compliance
Infrastructure security is paramount:
- IAM least privilege policies
- Security groups and network ACLs
- Secrets management (AWS Secrets Manager, Vault)
- Compliance (SOC2, HIPAA, PCI-DSS)
- Infrastructure security scanning (Trivy, Snyk)
