Brice I.

• Architected and operated production workloads on AWS EKS with multi-AZ resilience, supporting large-scale microservices and meeting 99.99% availability targets. • Designed reusable Terraform modules for VPC, IAM, EKS, RDS, ALB/Ingress, and Route53, cutting provisioning time by 60% and reducing environment drift. • Implemented GitOps delivery using ArgoCD and progressive delivery via Argo Rollouts (blue/green and canary), reducing deployment failures by 40%. • Built and standardized CI/CD pipelines using GitHub Actions and Jenkins, decreasing deployment time by 75% and improving release frequency from weekly to daily. • Established SRE operating model using SLO/SLI definitions and error budgets, reducing Sev-1 incidents by 35% through reliability-focused engineering decisions. • Implemented end-to-end observability using Prometheus, Grafana, Alertmanager, ELK Stack, and CloudWatch, reducing MTTR from 90 minutes to less than 30 minutes. • Tuned alerting and dashboards to improve signal-to-noise, lowering false-positive pages by 30% and improving on-call effectiveness. • Strengthened security controls with least-privilege IAM, Kubernetes RBAC, Vault secrets management, TLS/WAF, and automated scanning with Trivy, improving compliance readiness. • Implemented policy guardrails using OPA patterns for preventative controls, reducing misconfigurations reaching production by 25%. • Led incident response and postmortems (RCA, corrective actions, prevention plans), reducing repeat incidents by 45% through permanent fixes. • Improved traffic management by standardizing Ingress controllers and ALB routing, reducing routing-related production issues by 30%. • Optimized cloud cost via right-sizing, autoscaling, tagging governance, and S3 lifecycle policies, delivering $180K+ annual savings. • Designed and validated HA/DR processes including backup/restore testing and failover drills, meeting defined RTO/RPO targets consistently.

• Automated infrastructure provisioning using Terraform and CloudFormation, accelerating environment builds by 50% and improving repeatability across teams. • Containerized applications using Docker and deployed to EKS/GKE clusters, improving scalability and reducing infrastructure cost by 30%. • Built and maintained CI/CD pipelines in Jenkins, GitLab CI, and Azure DevOps, increasing deployment frequency by 300% while reducing manual release steps. • Standardized deployment packaging using Helm charts and Kustomize overlays, improving environment consistency across dev/test/prod. • Implemented controlled promotion and release workflows (approvals, artifact versioning, rollback strategy), reducing production release risk and downtime. • Integrated monitoring/logging with ELK and CloudWatch, improving time-to-detect by 40% and speeding up troubleshooting. • Reduced pipeline break-fix cycles by hardening build jobs and eliminating recurring failure causes through root-cause remediation and automation. • Improved source control governance with Git branching standards, PR workflows, and review gates, lowering merge conflicts and improving code quality. • Implemented security hardening for Kubernetes using RBAC, secrets management practices, and vulnerability scanning, reducing high/critical findings by 50% before release. • Tuned alerts and dashboards to reduce noise by 30%, aligning monitoring to operational outcomes and service health. • Automated routine operational tasks using Python/Bash, reducing manual work by 40% and improving execution consistency.

• Supported enterprise Linux environments (RHEL/Ubuntu/CentOS) for production systems, ensuring stability through disciplined operational support and maintenance. • Performed troubleshooting across OS, services, and connectivity layers, improving platform availability and reducing repeated escalations. • Automated operational checks and routine tasks using Bash and Python, reducing manual workload by 30% and improving consistency. • Supported network and platform services including DNS, load balancing concepts, and service connectivity during incident triage. • Participated in incident response and RCA activities, contributing to a 20% reduction in recurring infrastructure failures through corrective actions. • Assisted with capacity and performance tuning efforts, helping prevent saturation and reliability degradation during peak usage windows. • Supported change and release processes, coordinating maintenance activities to reduce unplanned downtime and improve execution quality. • Helped maintain backup/restore procedures and validation routines, improving recovery reliability and reducing restore failures. • Produced and maintained runbooks, SOPs, and operational documentation in Confluence, improving knowledge transfer and reducing tribal dependency. • Collaborated with cross-functional teams in Agile delivery environments, improving operational alignment with application release timelines.
