Hello! I'm Callum Alexander Fay, a seasoned technology professional with over a decade of experience in software development, DevOps, and cloud technologies.

Throughout my career, I've worked across the financial services industry, building expertise in containerization, Kubernetes, cloud platforms, and most recently, generative AI solutions. My journey has taken me through roles of increasing responsibility at major financial institutions, where I've focused on developing scalable, resilient systems.

I have a passion for emerging technologies and enjoy tackling complex problems with innovative solutions. My technical background spans both frontend and backend development, with particular depth in cloud-native architectures.

I'm keen to stay hands-on and be as involved as possible with fixing the issues at the coal face, believing that the best technical leaders never lose touch with implementation details.
