📦 Infrastructure Management & Automation- High-Availability Multicloud Kubernetes Clusters:Architected and automated high-availability Kubernetes clusters across AWS and GCP using Terraform and Ansible, achieving seamless multicloud connectivity and flexible scaling. This setup supports robust redundancy and continuous availability for critical workloads.- Cluster Management and Automated Updates:Streamlined the management of rollbacks, service updates, and OS upgrades, automating Kubernetes node draining and updates to maintain uptime. Integrated AWS EventBridge and AWS Lambdas for real-time event-driven workflows, enabling automated notifications and incident responses.- End-to-End Monitoring and Observability:Implemented comprehensive monitoring using OpenTelemetry for distributed tracing and integrated with Argocd for continuous delivery (CD). Leveraged Prometheus and Grafana for metrics collection and visualization, ensuring proactive incident detection and resource optimization.- Access Control and Security:Strengthened cluster security through fine-grained access control (RBAC and IAM) and secured internal communications using mTLS. Configured kubelet authentication and authorization to limit node access and implemented a custom ArgoCD setup to automate CD pipelines while ensuring consistency across environments.- Disaster Recovery and Data Resilience:Configured Velero for disaster recovery (DR), enabling scheduled backups and on-demand restores across cloud environments, ensuring data resilience and business continuity even during outages or infrastructure issues.📈 Secure Web Application Development- Developed and deployed a secure web application using Next.js and NGINX, integrating monitoring solutions (Betterstack, Posthog) and securing domains via Cloudflare.- Implemented custom server-side authentication with NextAuth and HttpOnly cookies, enhancing client-server security.

🌐 DevSecOps and Secure SDLC EnhancementsIn the realm of DevSecOps, I've spearheaded the integration of security measures within the Software Development Life Cycle (SDLC) through the application of Static Code Analysis (SCA) tools like SonarQube and Fortify, and the development of custom Jenkins plugins utilizing Java and Maven. This strategic approach not only enhanced security gates and controls but also bolstered SDLC security, all while minimizing cloud resource consumption.💻 Automated-Secure Infrastructure ProvisioningI am at the forefront of developing an innovative tool for automated kubeadm cluster provisioning, aimed at simplifying and securing cloud infrastructure setup. This cutting-edge tool leverages Terraform for infrastructure as code (IaC) and Ansible for configuration management, automating the entire infrastructure setup process from authentication to Role-Based Access Control (RBAC). This ensures a hands-off, secure, and efficient deployment of cloud resources, embodying the principles of Infrastructure as Code and automation.🔐 Full-Stack Development with Zero-Trust SecurityMy work in full-stack development embraces the Zero-Trust security model on a code and technology training platform. By implementing DevSecOps practices and managing cloud infrastructure, I utilize Continuous Integration/Continuous Deployment (CI/CD) pipelines with Jenkins, containerization with Docker, orchestration with Kubernetes, and microservices architectures to enhance security and operational efficiency. This approach is further supported by the integration of security scanning tools and automated testing frameworks to ensure the robustness and security of the platform.
