◎ Mission Profile

Senior Platform Engineer and Site Reliability Engineer with a background spanning mission-critical aerospace systems and large-scale cloud infrastructure. I design and build secure, multi-account AWS platforms — from account structure and networking to identity, container security, and observability — with a focus on operational consistency and production readiness at scale. I own technical roadmaps, align cross-functional stakeholders, and translate infrastructure decisions into business outcomes.
