Project Overview:
Leading critical infrastructure initiatives for IBM Cloud's Key Management Service, focusing on high availability, security, and automated operations at enterprise scale.
Key Responsibilities:
- Architected and maintained CI/CD pipelines for automated testing and deployment
- Designed observability solutions for containerized services
- Led secret rotation and security automation initiatives
Technical Environment:
- Cloud Services: IBM Cloud's Key Management Service, Secrets Manager, LogDNA, IKS(Managed Kubernetes), Postgres DB
- Tools: Jenkins, Docker, Ansible, Kubernetes, Prometheus, Linux, Terraform
- Languages: Golang, Python, Bash
Major Achievements:
- Enterprise-Scale Secret Management Automation
- Challenge: Manual secret rotation across multiple services created significant security risks and operational burden. Quarterly compliance requirements were time-intensive, pulling team resources from critical development work and increasing risk of human error.
- Solution & Impact: Architected an automated secret rotation pipeline with built-in compliance checks and manual override capabilities. The system automatically handled quarterly rotations while enabling on-demand updates when needed.
- This resulted in:
- 85% reduction in credential management time
- 100% compliance maintenance
- Enhanced security posture through elimination of manual handling
- Freed engineering resources for strategic initiatives
- Kubernetes Network Architecture Optimization
- Challenge: Complex multi-region architecture requiring service-to-service communication through public APIs, creating unnecessary security risks and operational complexity. Multiple authentication layers, region-specific credentials, and both on-prem/cloud deployment options complicated the infrastructure.
- Solution & Impact:Implemented pod-to-pod communication strategy through Kubernetes networking configurations, revolutionizing our service architecture.
- This resulted in:
- Eliminating need for external API calls between services
- Removed authentication/authorization complexity
- Reduced security attack surface
- Simplified multi-region deployment architecture
- Decreased operational overhead for credential management
- Advanced CI/CD Pipeline Evolution
- Challenge: Need for reliable, secure, and efficient multi-region deployment process supporting extensive testing requirements and compliance checks. Migration from Jenkins to Tekton required maintaining service reliability while enhancing automation capabilities.
- Solution & Impact: Led the design and implementation of comprehensive CI/CD pipelines, evolving from Jenkins to Tekton while expanding automation coverage:
- Automated feature testing integration
- Enhanced compliance verification systems
- Implemented robust load testing frameworks
- Created multi-region deployment orchestration
- Built automated monitoring and logging analysis
- Reduced deployment issues through improved testing automation
Key Learnings:
- Importance of automation in maintaining security at scale
- Balance between innovation speed and operational stability
- Critical role of observability in modern cloud services
Skills Advanced:
- Container Orchestration
- Infrastructure as Code
- CI/CD Pipeline Design
- Cloud Security
