About Me

Brian O'Reilly

Brian O'Reilly

I am a strategic data leader passionate about solving complex business challenges by building robust data platforms and fostering data-driven cultures. With a First Class Honours degree in Business Information Systems and over a decade of experience, I've led teams and initiatives across multiple industries, from finance to enterprise software.

My work focuses on creating tangible value—whether that's surfacing millions in revenue, saving thousands of hours in manual work, or establishing governance that stands the test of rapid corporate growth. I am a continuous learner, currently exploring Azure AI and Generative AI, and I thrive on turning chaotic data into a clear strategic advantage.

Based in Spain, available for remote or hybrid projects in Europe.
