NAGA SAHITH YANNAM

Designed and operated Akkeris, an internal Platform-as-a-Service (PaaS) that provides developers with self-service infrastructure provisioning, application deployments, observability, and operational capabilities on AWS.

• Built and maintained a developer self-service platform that abstracted infrastructure complexity while enforcing security, compliance, monitoring, and automated failover capabilities.
• Designed reusable Terraform modules for S3, RDS, ElastiCache, Elasticsearch, networking resources, and platform services to standardize infrastructure provisioning.
• Migrated existing AWS resources into Terraform state without service disruption, establishing infrastructure-as-code governance.
• Managed production multi-cluster Kubernetes environments on Amazon EKS supporting highly available containerized applications.
• Migrated workloads from on-premises Kubernetes clusters to AWS EKS using Velero and Karpenter, improving scalability and resilience.
• Leveraged Karpenter for intelligent node provisioning and resource optimization.
• Standardized deployments using Helm charts and implemented GitOps workflows through ArgoCD to automate application synchronization and drift detection.
• Designed and maintained CI/CD pipelines using Jenkins and GitHub Actions enabling reliable and repeatable deployments.
• Implemented service-to-service traffic management and observability using Istio service mesh.
• Secured application secrets and encryption keys using AWS Secrets Manager and KMS while enforcing IAM least-privilege policies.
• Built observability platforms using Prometheus, Grafana, OpenTelemetry, Coralogix, InfluxDB, and CloudWatch for centralized metrics, logs, and distributed tracing.
• Defined SLIs, SLOs, and error budgets to establish service reliability objectives and operational excellence practices.
• Reduced downtime by approximately 70% through telemetry-driven alerting, automated recovery mechanisms, and resilient infrastructure design.
• Integrated monitoring systems with PagerDuty and participated in incident response, root cause analysis, and postmortem processes to reduce MTTR.
• Contributed to FinOps initiatives through rightsizing, autoscaling, tagging strategies, and infrastructure governance to optimize AWS spending.
• Built reusable infrastructure patterns suitable for AI-enabled applications, model-serving workloads, and emerging LLMOps requirements.
• Collaborated closely with engineering teams to improve developer experience and accelerate software delivery.
