Sr. AWS DevOps Engineer at Webfirst, Inc.
January 1, 2023 - November 6, 2025
Led design and operation of a multi-account AWS landing zone using Control Tower, Organizations, SCPs, and IAM Identity Center, reducing misconfigurations and unauthorized changes by standardizing guardrails and account provisioning. Migrated core services to serverless (Lambda, API Gateway, DynamoDB, S3), reducing infrastructure overhead by 25% and lowering p95 latency through event-driven patterns and provisioned concurrency. Built end-to-end CI/CD with Jenkins → GitHub Actions + CodePipeline/CodeBuild/CodeDeploy, implementing canary and blue-green deployments; deployment lead time dropped 40% and change failure rate improved. Stood up EKS with managed node groups + Karpenter, Helm-based releases, and ALB Ingress; container startup time and cluster utilization improved while SLA remained at 99.9%+. Implemented policy-as-code and IaC scanning (tfsec, Checkov, OPA/Conftest) and image scanning (Trivy) in the pipeline; blocked noncompliant changes pre-merge and improved audit outcomes.
Sr. AWS DevOps Engineer at Juniper Networks
December 1, 2022 - December 1, 2022
Led a 23-member DevOps group through cloud modernization; standardized Terraform module catalog and GitOps (Argo CD) for repeatable, auditable deployments across dev/stage/prod. Migrated on-prem apps to AWS (EC2, RDS/Aurora, EKS), introducing autoscaling and multi-AZ failover; realized 20% cost reduction and 99.99% availability on critical paths. Established CI/CD with GitLab CI and CodePipeline, adding SBOM (Syft/Grype), SAST (SonarQube), and DAST (OWASP ZAP) gates; raised release confidence and reduced vulnerabilities shipped to prod. Implemented service mesh (App Mesh/Istio) with mTLS and fine-grained traffic policies in EKS; improved east-west security and canary rollouts. Automated patching/compliance baselines via Systems Manager Patch Manager, State Manager, and Ansible; cut manual toil by 50% and improved audit evidence readiness. Built observability stack with Prometheus + Grafana, CloudWatch metrics/alarms, and custom exporters; capacity planning stabilized and noisy alerts d
DevOps Engineer at JJTech Inc. (Client: Innovative Life Solutions)
February 1, 2019 - February 1, 2019
Engineered multi-region AWS architectures with Terraform/CloudFormation and reusable modules; accelerated environment builds and reduced drift across accounts. Built Dockerized microservices and Kubernetes deployments with Jenkins pipelines and Helm; cut release cycles by 35% while improving rollback confidence. Implemented secure CI/CD to AWS using CodePipeline/CodeBuild/CodeDeploy and GitHub/Bitbucket; added branch protections, approvals, and artifact signing. Deployed Kinesis → Lambda → S3 serverless streams for real-time processing; simplified downstream analytics and alerting. Stood up centralized logging with OpenSearch/ELK and CloudWatch Logs; root-cause analysis times dropped thanks to structured fields and trace correlation. Automated patch/compliance across accounts using Systems Manager (Run Command, Patch Manager) and parameterized baselines; reduced maintenance windows and outages. Applied cost controls (RI/Savings Plans, S3 lifecycle to Glacier, compute rightsizing) a
AWS DevOps Infrastructure Engineer at JJTech Inc. (Client: Compass Inc.)
December 1, 2017 - December 1, 2017
Built foundational VPCs (private/public subnets, NAT, NACLs, SGs), Transit Gateway/peering, and Direct Connect; established segmented, scalable network topologies. Authored CloudFormation (nested stacks) and early Terraform for repeatable infra; slashed environment build time by 60% and improved parity across stages. Stood up self-managed Kubernetes on EC2 and Docker Swarm (pre-EKS) with Jenkins pipelines; enabled blue-green and canary strategies to de-risk releases. Implemented CloudWatch metrics/alarms, custom log enrichment, and SNS/PagerDuty notifications; reduced MTTR through actionable runbooks. Enforced encryption at rest (KMS) and in transit (TLS), key rotation, and secrets management; passed internal security reviews without critical findings. Introduced Packer-built golden AMIs and SSM Session Manager; improved node hygiene and access auditability. Drove cost hygiene with RI planning, S3 lifecycle policies, and automated idle resource cleanup; saved double-digit percentages m
Infrastructure Support Analyst (Intern) at Orange Cameroon
November 1, 2014 - November 1, 2014
