Professional Summary

Who I am and what I focus on

Senior DevSecOps and Site Reliability Engineer with end-to-end ownership of CI/CD platforms in regulated, enterprise environments. I design, implement and govern Jenkins / CloudBees and Octopus Deploy ecosystems, automate certificate and PKI workflows, and help teams ship securely, consistently and with confidence.

Recent work includes leading Octopus Deploy rollout and automation across Allstate Canada, hardening and modernising CloudBees Jenkins, driving SecureFlow CI/CD standards, and engineering certificate lifecycle automation across Windows and Linux estates.

Approach & Philosophy

How I think about DevSecOps, reliability and platforms

I treat CI/CD and deployment tooling as products: with clear ownership, documentation, and predictable interfaces. Good platforms make the secure, correct path the easiest one.

I favour opinionated standards over ad-hoc solutions. Shared libraries, reusable templates and runbooks reduce cognitive load, improve auditability, and let teams move faster without re-solving the same problems.

My work balances reliability, security and developer experience: automation should be transparent, debuggable, and aligned with compliance — not a black box that teams work around.

Mentoring, documentation, and cross-team collaboration are core parts of the role: they turn platform decisions into organisational capability, not individual heroics.
