With over a decade in managing AWS infrastructure and working extensively with Terraform, I'm confident that I can deliver the Sonatype Nexus configuration project you're seeking. The mention of S3 integration, NLB configuration, DNS setup with custom domain names on AWS Route 53 underscores the need for a seasoned AWS professional to ensure success, and that's exactly what I bring to the table.
I have a comprehensive understanding of Sonatype Nexus, knowing its quirks and capabilities, all of which would be useful during the setup process. Moreover, I have vast experience in SSL setup and configuration and integrating SaaS applications, skills which are invaluable when ensuring security requirements are met at an expert level.
Additionally, my proficiency in automation tools like PowerShell, Ansible, Terraform will come in handy as we work towards creating an infrastructure for Sonatype Nexus that is not only complete but also functional. Let's make your AWS dream a reality together!
