Sai Krishna

Practical, outcome-driven DevOps Engineer with 5+ years of experience building reliable, automated, and secure cloud-native platforms across financial services and telecom domains. Strong expertise in designing, implementing, and operating CI/CD pipelines, Infrastructure-as-Code, container orchestration, and production-grade observability to support high-availability systems. Proven track record working with enterprise-scale organizations, including Manulife Financial, Rogers Communications, delivering scalable and resilient DevOps solutions.

Hands-on experience modernizing legacy pipelines, migrating workloads to Kubernetes and public cloud environments, and enabling microservices-based architectures. Deep knowledge of SRE and DevOps best practices, including GitOps, automated rollbacks, canary/blue-green deployments, and proactive monitoring to reduce deployment lead time and production incidents. Strong scripting and automation skills using Python and Bash, combined with infrastructure automation through Terraform and Ansible.

Advanced experience in observability and monitoring using Prometheus, Grafana, and Datadog, with a focus on improving MTTR, system reliability, and developer productivity.

DevOps Engineer at Manulife Financial (2023-04 – Present)

• Designed and maintained GitOps-driven CI/CD pipelines using GitHub Actions and ArgoCD, delivering >20 microservice deployments per day with automated rollbacks and canary strategies.
• Implemented Infrastructure-as-Code for multi-account AWS environments using Terraform and remote state (Workspaces/S3 + locking), reducing environment provisioning time from days to <2 hours.
• Built and operated a container platform on Kubernetes (EKS), created Helm charts and operators for standardized deployments, and supported autoscaling and multi-zone resilience.
• Led observability and SRE initiatives: instrumented services with Prometheus and Grafana for metrics, integrated Datadog for APM and alerts, and established SLO/SLI/alerting playbooks to lower MTTR.
• Automated secrets management using Vault and implemented RBAC + OIDC for cluster access and CI. Hardened images using scanning tools and integrated container image signing.
• Introduced IaC testing, drift detection, and policy-as-code (Sentinel/OPA) in pipelines to improve compliance and deployment safety.
• Mentored cross-functional dev teams on GitOps practices, infrastructure testing, and purple/blue-green deploy patterns — helped reduce failed deployments by a measurable margin.

DevOps Engineer at Rogers Communications (2020-03 – 2023-05)

• Migrated monolithic build pipelines to containerized CI with Jenkins and GitLab/GitHub, introduced pipeline-as-code, and parallelized test stages to shrink build times by 40%.
• Provisioned and automated infrastructure with Terraform and configuration management using Ansible, enabling consistent dev/test/prod environments and predictable rollouts.
• Adopted Docker + Kubernetes for microservice deployments; developed Helm charts, configured cluster autoscaling, and namespace-based isolation for teams.
• Established logging and monitoring stacks: ELK for centralized logs, Prometheus/Grafana for metrics, and PagerDuty for on-call rotations — improved incident detection and response times.
• Automated CI/CD security checks and dependency scanning (Snyk/Trivy), and integrated infrastructure scanning into pipelines for compliance with telecom security policies.
• Collaborated with networking and cloud teams to move selected workloads to AWS and implement hybrid-cloud connectivity and observability.
