2. Multi-Cloud Infrastructure as Code¶
Technologies: Terraform, AWS, Azure, Bicep, Ansible
Description: Built reusable infrastructure modules for multi-cloud deployments with automated provisioning and configuration management.
Key Achievements: - Created 50+ reusable Terraform modules - Implemented cost optimization strategies saving 30% monthly - Set up automated compliance and security policies - Enabled self-service infrastructure provisioning
Infrastructure Components: - Virtual networks and subnets - Load balancers and auto-scaling groups - Database clusters with high availability - Monitoring and logging stacks - Security groups and IAM policies
3. Kubernetes Platform Migration¶
Technologies: Kubernetes, Helm, Istio, Prometheus, Grafana
Description: Led the migration of 20+ microservices from monolithic architecture to containerized Kubernetes deployments.
Key Achievements: - Migrated legacy applications with zero downtime - Implemented service mesh for traffic management - Set up comprehensive monitoring and alerting - Achieved 99.9% uptime post-migration
Migration Strategy: 1. Assessment: Analyzed existing applications and dependencies 2. Containerization: Created Docker images with multi-stage builds 3. Orchestration: Deployed to Kubernetes with Helm charts 4. Networking: Implemented Istio service mesh 5. Monitoring: Set up Prometheus and Grafana dashboards
4. DevSecOps Implementation¶
Technologies: SonarQube, OWASP ZAP, Trivy, Terraform, Azure Policy
Description: Integrated security practices throughout the development lifecycle with automated security testing and compliance.
Key Achievements: - Implemented SAST/SCA/DAST in CI/CD pipelines - Reduced security vulnerabilities by 70% - Automated compliance reporting - Trained teams on secure coding practices
