BERTRAND BATE

Migrated 15 production microservices from EC2 to Amazon EKS on Fargate, managing Kubernetes deployments, Helm releases, scaling, monitoring, and operational reliability for large-scale IoT workloads. Administered EKS environments with cluster troubleshooting, resource optimization, workload scaling, and operational automation. Automated secret rotation workflows using HashiCorp Vault, AWS Lambda, RDS PostgreSQL, and MongoDB Atlas, eliminating weekly manual credential management. Improved observability and incident handling by implementing CloudWatch anomaly detection, SLO-based alerting, and PagerDuty playbooks, reducing false positives. Reduced MTTR from 45 minutes to 18 minutes through proactive monitoring and automation. Built secure GitLab CI/CD pipelines using Packer and Ansible to automate hardened AMI image creation and weekly patching via IaC. Reduced vulnerability remediation timelines from 14 days to 24 hours, supporting SOC2 compliance with zero audit findings.

Re-architected enterprise DevOps platforms using GitHub Actions, Terraform Cloud, and AWS services for automated infrastructure provisioning, CI/CD deployments, Kubernetes environments, and cloud-native application delivery. Reduced deployment windows from 6 hours to 70 minutes while eliminating configuration drift through IaC standardization and Terraform automation. Designed and deployed a streaming analytics platform using Amazon Kinesis, AWS Lambda, and OpenSearch for high event throughput, improving conversion tracking accuracy. Implemented least-privilege IAM governance using CloudFormation Guard and AWS IAM Access Analyzer, remediating critical security audit findings. Achieved 100% SOC2 compliance within two weeks by automating IAM reviews, security policy validation, and cloud governance workflows. Managed end-to-end infrastructure lifecycle across dev, staging, and production including provisioning, CI/CD automation, environment standardization, and deployment workflows.

Led migration of 200+ enterprise applications from legacy high-availability clusters to AWS, supporting 45 application teams through EKS cluster provisioning and Route53 DNS configurations. Completed enterprise cloud migration three weeks early with zero production incidents by applying scalable Kubernetes and AWS architecture standards. Automated TLS certificate lifecycle management using Jenkins pipelines, cert-manager, and Venafi integrations, reducing provisioning time and preventing certificate-related outages. Partnered with HashiCorp Vault teams to secure MongoDB, PostgreSQL, and AMQ credentials and removed hardcoded secrets from repositories. Improved Kubernetes stability with HPA tuning, pod resource optimization, and created 25+ operational runbooks. Applied SRE practices including SLO-based alerting, monitoring improvements, incident response automation, and reliability engineering, increasing pod uptime and reducing incident volume and MTTR across production EKS environment
