Senior Site Reliability Engineer @ PathAI

About

With over fourteen years of professional experience, I specialize in site reliability engineering, with a focus on Kubernetes, AWS, and scalable infrastructure solutions. At Indeed, I contributed to the mission of helping people get jobs by driving cloud migrations and ensuring performance and reliability standards. I thrive in collaborative environments and am motivated by solving complex technical challenges that enable organizational growth and innovation. At Indeed, I spearheaded the migration of over 50,000 pods to Amazon EKS, ensuring seamless performance for product teams and users. My expertise in Kubernetes and AWS allowed me to collaborate with hundreds of teams, transitioning on-premise deployments to cloud-native solutions with zero user impact. Additionally, I introduced automation strategies that improved deployment efficiency and reliability across the organization.
