About Ayan Adesigbin

I\'m an experienced DevOps Engineer with 8 years of expertise in building, automating, and managing CI/CD pipelines using tools like Jenkins to streamline the deployment of applications and services across diverse cloud platforms. My practical knowledge involves using modern containerization technologies like Docker and Kubernetes, enabling efficient orchestration of microservices architectures. I specialize in deploying secure, scalable, and fault-tolerant infrastructure, leveraging Terraform and Ansible on Azure and AWS platforms. I\'m well-versed in creating highly available and resilient environments across multi-cloud infrastructures.

Experience

1. Devops Engineer

   TEKsystems

   Nov 2023 — Present

   Orchestrated the end-to-end automation of infrastructure provisioning on AWS and Azure using Terraform and Ansible, reducing manual setup time by over 70% and ensuring consistent, repeatable environments. Engineered and optimized robust CI/CD pipelines using Jenkins, GitLab CI, and Azure DevOps, accelerating release velocity by 45% and minimizing deployment failures through automated testing and quality gates. Spearheaded the containerization of monolithic/microservice applications using Docker and orchestrated them on managed Kubernetes services (EKS, AKS), improving application scalability and resource utilization by 60% while reducing infrastructure costs. Led the migration of on-premises infrastructure to AWS and Azure, designing secure, highly available cloud architectures (VPC, IAM, Load Balancers) that enhanced system resilience and achieved 99.9% uptime. Implemented a comprehensive monitoring stack using Prometheus, Grafana, and the ELK stack, decreasing Mean Time to Resolution (MTTR) for production incidents by 50% through proactive alerting and centralized logging. Strengthened security posture by integrating security tools into the pipeline and enforcing compliance checks, resulting in a 40% reduction in vulnerabilities prior to production deployment. Mentored development teams on DevOps best practices, including Git branching strategies and CI/CD concepts, fostering a collaborative culture and improving cross-functional workflow efficiency.
