To Whom It May Concern,

It is a genuine pleasure to recommend Damon Ellerbee, who worked with me as a Senior Software Engineer (SE-IV) at PDI Technologies. During our time working together, he consistently demonstrated strong technical skill, sound judgment, and a thoughtful approach to building software.

Damon is a capable full-stack engineer with a solid understanding of CI/CD and cloud-based systems. He was especially effective at debugging legacy systems and applying sustainable, long-term fixes, as well as improving integrations and designing clear, reliable workflows. He approached complex systems with care, focusing not just on solving the immediate problem but on building solutions that would hold up over time.

What I appreciated most was his emphasis on clarity and maintainability. His code was easy to understand, well-structured, and supported by good documentation, which made it easier for the rest of the team to work with and extend. He also made good use of modern tools, including AI, to improve quality and efficiency without sacrificing thoughtful design.

He also genuinely enjoys learning, figuring things out, and sharing what he knows. He was always helpful to teammates and collaborated easily across teams, products, and departments, which made him a trusted and valued partner on larger initiatives.

Damon is dependable, collaborative, and professional. He took ownership of his work and was someone I could trust to handle important responsibilities. I would recommend him with confidence and would gladly work with him again.

Sincerely,
Meagan Rowell
