MICHEAL ADUFE

• Dell is one of the top OEM providers to the telecommunication and IT industry in the United States and around the world. In this project, as a Cloud DevOps Engineer, I manage AWS resources in the cloud and maintain Continuous Integration and Continuous Deployment (CI/CD) pipeline for a fast-paced robust application development environment.
  Contributions:
  • Set up CI/CD pipelines for Microservices and integrated tools such as Maven, Bitbucket, SonarQube, Nexus, Docker, and Slack for providing immediate feedback to DEV teams after code check-in.
  • Wrote Ansible playbooks from scratch in YAML. Installing, setting up & Troubleshooting Ansible, created and automated platform environment setup.
  • Set up Git repositories and SSH Keys in GitHub for Agile teams.
  • Integrated GitHub webhooks into Jenkins to automate the code check-out process.
  • Implemented the setup for master-slave architecture to improve the performance of Jenkins.
  • Created Dockerfile and automated docker image creation using Jenkins and Docker.
  • Automated infrastructure provisioning on AWS using Terraform and Ansible.
  • Created nightly builds with integration to code quality tools such as SonarQube and Veracode.
  • Created quality gates in the SonarQube dashboard and enforced them in the pipelines to fail the builds when conditions were not met.
  • Rebuild the entire existing platform over to Docker containers.
  • Set up Kubernetes clusters using Amazon EKS.
  • Set up repos on Azure Git, merging code from the develop branch to the main branch
  and preparing it for deployment.
  • Migrated legacy applications to Microsoft Azure Cloud PaaS by setting up CI/CD pipelines on AzureDevOps
  • We created WebApps (PaaS solutions) on the Azure portal for deploying web applications using Azure DevOps pipelines.

• I have expertise in managing and automating infrastructure deployment using tools like Terraform and AWS CloudFormation. I am proficient in building CI/CD pipelines using tools like Jenkins and GitHub CI/CD. I have experience in containerization technologies like Docker and container orchestration platforms like Kubernetes.
  I have worked on various projects, ranging from small startups to large enterprise environments. I have a proven track record of delivering high-quality solutions on time and within budget. I am constantly learning and keeping up with the latest trends and best practices in the DevOps field.
  Contributions:
  • Experienced with EC2, VPC, Route53, ELB, S3, EMR, Redshift, supporting networking
  and management/monitoring services
  • Developing high-quality, enterprise-scale software products using AWS technologies such as AWS Code Commit, CodeBuild, Code Deploy, and Code Pipeline. Building enterprise-class, highly available CI / CD pipelines from code in a highly elastic, cloud-native environment.
  • Application, server, and network security. Worked on infrastructure with Docker containerization; Kubernetes is being used to orchestrate Docker Containers' deployment, scaling, and management.
  • I worked on Micro Services deployments on AWS ECS and EC2 instances, actively worked on Docker, and deployed and maintained Microservices in a Dev and QA environment.
  • Implemented docker-maven-plugin in maven pom.xml to build docker images for all
  microservices and later used Docker file to build the docker images from the java jar files
  • DevOps Tools: Packer, Jenkins, Terraform, Puppet, Docker • OS: Windows, Linux •
  Software: Apache, Nginx • Container Technology & Management: Kubernetes, Docker, Docker Swarm • Programming: Shell, Bash, Python, NodeJS, PHP
  • Shared best practices and guides with engineers while implementing Infrastructure as a code, using Terraform or
  • Cloud formation

• Troubleshoot and identified all faulty hardware issues on customer IN/VAS Linux server
platforms
• Planned activities around the replacement of defective hardware on Linux servers
• Effectively communicated with the customers on server maintenance’s impact on live
traffic.
• They reviewed maintenance’s MOPs with the customer and level 2 support Engineers to
assure the customer of resolving any issues arising from maintenance activities.
• Wrote Cron. Scripts to perform several scheduled activities like database backups and
purging of log files

Contributions:
• Ensured 24/7 uptime on clients’ Server Platforms
• Performed hardware and software installation and upgrades on servers and storage such
as hard discs, RAMs, Motherboard, SCSI, Tape-drives, lithium batteries, Fan, PSU
(power supply unit), and operating systems like Oracle Solaris and HP-UX operating
system. (e.g., SUN, HP, and ALPHA servers)
• Performed fault troubleshooting of server hardware and software
• Consulted in the procurement and Installation of Field Replacement Units (FRUs)
• Performed Monthly health checks on customer’s servers and scheduled preventive
maintenance
