Experience
Cloud DevOps Lead
- Architected a CSO-approved, secure GenAI infrastructure utilizing AWS Bedrock, OpenSearch, and ECS, ensuring enterprise-grade scalability and compliance.
- Directed a DevOps team to deploy a production-ready Generative AI banking solution within a high-pressure 2-week timeframe, including full CI/CD pipeline integration.
- Modernized legacy infrastructure by architecting and executing the migration of VM-hosted applications to a high-availability OpenShift Kubernetes environment.
- Orchestrated a large-scale CI/CD migration from Jenkins to GitLab CI, seamlessly integrating a comprehensive DevSecOps toolchain including SonarQube, Veracode, Nexus, and Prisma Cloud for end-to-end security and quality gates.
- Empowered developer self-service by designing a centralized GitLab CI component library, reducing pipeline configuration time and enforcing global standards.
Senior DevOps Engineer
- Architected a high-availability (HA) monitoring ecosystem using Prometheus and Thanos, enabling long-term metric retention and global query capabilities across multiple clusters.
- Engineered a custom Kubernetes controller in Golang to automate ConfigMap synchronization, significantly reducing manual configuration overhead and deployment errors.
- Developed a standardized library of Terraform modules for AWS ALB and resource provisioning, accelerating infrastructure deployment through Infrastructure-as-Code (IaC) best practices.
- Automated data resiliency by developing AWS Lambda functions for scheduled EC2 EBS volume snapshots, ensuring robust disaster recovery and cost-effective backup management.
DevOps Engineer
- Defined and executed a strategic Continuous Delivery (CD) roadmap using Jenkins, Docker, and Helm, streamlining application delivery from development to production.
- Enhanced deployment reliability by implementing Canary release strategies on production EKS clusters, minimizing the impact of potential regressions. Evaluated OSS tools like Twitter Diffy for traffic shadowing.
- Provisioned secure, compliant AWS infrastructure using CloudFormation, ensuring consistent environment replication and adherence to Infrastructure-as-Code (IaC) principles.
- Engineered a proactive observability pipeline featuring robust monitoring and automated alerting integrated with MS Teams and email for rapid incident response.
