Dear Hiring Manager,

I am writing to express my interest in the Infrastructure & Cybersecurity Architect position. With over eight years of hands-on experience in infrastructure architecture, cloud security, and compliance-driven engineering, I have led secure, scalable system deployments across hybrid environments while strictly adhering to frameworks like NIST, DFARS, and FedRAMP. My background uniquely combines deep technical execution with architectural vision, making me well-suited for this doer-leader role.

In my most recent work, I designed and deployed secure AWS and hybrid architectures using Terraform, Ansible, and CI/CD pipelines, supporting mission-critical applications with 99.99% uptime. I conducted risk assessments, implemented continuous compliance with NIST 800-53 and DoD STIGs, and authored automated hardening scripts in Bash and Python to enforce baseline security on Linux and Windows systems. I also developed hardened AMIs with Packer, embedding TPM 2.0, Secure Boot, and IMDSv2 to meet audit and operational integrity goals. In addition to infrastructure and compliance, I’ve actively managed endpoint hardening, identity and access management (IAM), vulnerability scanning (using tools like AWS Inspector and Nessus), and incident response across cloud and on-premises networks. My experience includes managing vendor compliance, reviewing third-party solutions, and collaborating with internal audit and compliance teams to maintain security certifications and audit readiness. Highlights of my qualifications include:

• Architected secure, redundant infrastructure across hybrid (AWS/on-prem) environments.

• Implemented NIST CSF and DFARS-aligned controls, with audit documentation and response.

• Deployed and maintained SIEM, EDR, and vulnerability management platforms.

• Automated patching, logging, and security baselines using Bash, Python, and Ansible.

• Designed DR/HA strategies and performed security impact analyses for major upgrades.

• Led cross-functional technical implementations in defense and logistics environments.

• Hold active AWS Security Specialty and Solutions Architect–Professional certifications. I am excited by the opportunity to bring secure, resilient infrastructure to a fast-moving maritime environment, and would welcome the chance to contribute my experience to your mission. I look forward to discussing how I can support your team’s goals. Thank you for your consideration.

Sincerely,

Emmanuel Dibia
