EMMANUEL A.

• Built and operated Kubernetes-based cloud-native platforms on AWS supporting 15+ microservices across development, staging, and production environments. • Designed and maintained secure GitLab CI/CD pipelines and automated release workflows, reducing deployment time by up to 70%. • Implemented GitOps-based application delivery using Argo CD and Helm, improving deployment consistency, traceability, and rollback capabilities. • Automated AWS infrastructure provisioning and lifecycle management using Terraform and Infrastructure as Code, reducing environment setup from days to under one hour. • Hardened CI/CD pipelines with vulnerability scanning, dependency validation, code-quality gates, image security checks, secrets detection, and software supply-chain controls. • Implemented secrets and access-management solutions using AWS Secrets Manager, Kubernetes Secrets, IAM, RBAC, and least-privilege practices. • Built observability capabilities using Prometheus, Grafana, Loki, OpenTelemetry and Jaeger for metrics, logs, distributed tracing, dashboards and alerting. • Improved production troubleshooting and incident response through monitoring, alerting and root-cause analysis, contributing to a 35% reduction in MTTR. • Improved deployment quality through CI/CD controls and environment hardening, reducing deployment defects by approximately 35%. • Standardized AWS resource tagging and infrastructure governance and contributed to cloud optimization initiatives that reduced operating costs by approximately 30%. • Collaborated with development, security and operations teams on platform reliability, scalability, production incidents and continuous improvement.

• Contributed to migration initiatives from monolithic applications to microservices-based architectures deployed on Kubernetes platforms. • Built and maintained CI/CD pipelines supporting automated testing, container image creation, and application deployments across multiple environments. • Automated infrastructure provisioning and deployment workflows using Terraform, Bash scripting, and Infrastructure as Code (IaC) best practices. • Implemented centralized monitoring, logging, and observability solutions using Prometheus, Grafana, and related tools to improve platform visibility and operational support capabilities. • Supported Linux-based production environments and participated in troubleshooting, incident response, root-cause analysis, and operational issue resolution. • Collaborated with development teams to improve deployment reliability, automation, release processes, and overall software delivery efficiency. • Maintained Kubernetes environments supporting containerized applications and platform services, ensuring system availability, scalability, and operational stability. • Assisted with secrets management and secure configuration practices, supporting the protection of application credentials and sensitive infrastructure data.

• Administered Linux-based servers across on-premises and cloud-hosted environments, ensuring system availability, security, and performance. • Managed system configuration, patching, package lifecycle management, and operating system maintenance to maintain stable and secure infrastructure. • Implemented user access management and role-based access control (RBAC) policies following least-privilege security principles. • Configured and maintained core infrastructure services including DNS, DHCP, NTP, SMTP, SSH, and VPN solutions to support business operations. • Supported networking operations, including firewall administration, routing, switching, and secure connectivity across distributed environments. • Automated routine operational tasks using Bash scripting, cron jobs, and system automation tools to improve efficiency and reduce manual effort. • Monitored infrastructure health, system performance, and service availability, while participating in incident troubleshooting and issue resolution. • Collaborated with engineering and operations teams to improve infrastructure stability, security, and overall operational reliability. • Maintained system documentation, operational procedures, and configuration standards to support consistent infrastructure management and knowledge sharing.
