• As a seasoned DevOps Engineer I played a crucial role in supporting the organization's cutting-edge infrastructure platform. By leveraging the power of Infrastructure as Code (IAC) technologies such as Terraform, Terragrunt, atlantis.io and Kubernetes, I was able to streamline deployment processes and enhance the reliability and scalability of the infrastructure.• I also had the opportunity to contribute to the implementation of a highly automated GitLab CI/CD pipeline, which further optimized the software delivery cycle and ensured the highest level of efficiency. My technical expertise and attention to detail proved invaluable in providing technical support and troubleshooting for the infrastructure platform.• My experience at Rivian not only gave me a chance to work with some of the most innovative technologies in the field, but it also honed my skills in managing and scaling cloud infrastructure.

• As a senior member of a team, I supported Adobe's Creative Cloud services running on the Ethos/adobe.io platform in a true DevOps role. Focusing on automation and efficiency, I managed CI/CD pipelines and infrastructure on both AWS and Azure using cloud-formation, ARM templates, and terraform to streamline deployment processes.• My expertise in metrics, reporting, and alerting was critical in ensuring the smooth functioning of the services, and I utilized Prometheus and Grafana for real-time insights and monitoring. The services ran as dockerized containers on the Adobe Ethos platform and were designed to automatically scale based on demand, making them highly available and resilient.• To optimize the software delivery cycle and testing, I implemented robust CI/CD pipelines using Jenkins and GoCD, which triggered automation and testing based on pull requests. I placed a high emphasis on the security of the services and utilized Hashicorp Vault for secrets management to ensure maximum data protection.• In the event of issues, I was responsible for troubleshooting the services using tools such as Splunk, Grafana, and other relevant technologies.
