• Designed and implemented a multi-tenant SaaS reference architecture on AWS EKS, leveraging Terraform, Helm, and GitOps (ArgoCD & Argo Workflows) to automate infrastructure and application lifecycle management.
• Built a secure control plane deploying networking, compute, database, monitoring, and logging stacks through AWS CodePipeline, integrating self-hosted GitHub Actions runners for CI/CD.
• Automated tenant onboarding workflows with CodeBuild to provision siloed and pooled tenant infrastructure, enforcing strict IAM and Kubernetes RBAC policies to ensure isolation and compliance.
• Implemented centralized observability with Grafana, CloudWatch, Athena, and Prometheus, and integrated monitoring dashboards for cost visibility and system health.
• Integrated Route53, ACM, and SES for domain management, SSL certificates, and email services, ensuring production-grade reliability and secure communication.
• Established best practices in DDD, microservices, and event-driven architecture, enabling scalable and modular SaaS deployments.
