Geoffrey Miller
Infrastructure Director & Principal Cloud Architect
With over 12 years of experience in cloud architecture and platform engineering, I specialize in designing, building, and operating scalable cloud platforms that enable engineering teams to deliver value faster and more reliably.
About Me
I'm passionate about building platforms that empower developers and accelerate innovation. Currently serving as Infrastructure Director at First Citizens Bank, I lead teams that design and operate cloud-native platforms serving thousands of engineers and millions of customers.
My expertise spans the full spectrum of platform engineering - from Kubernetes orchestration and service mesh architecture to developer experience and organizational transformation. I believe in the power of automation, observability, and treating infrastructure as a product.
When I'm not architecting the next generation of cloud platforms, you'll find me contributing to open source projects, mentoring fellow engineers, and sharing knowledge through writing and speaking at industry conferences.
