Name: Denise Day, Chief Information Officer, dunnhumby


Throughout my career my focus has been data, data management, technology, and software development. Today I am interim CIO, but I began my technology career four decades ago developing and coding data solutions – this was long before IT was a ‘thing’ or Windows existed commercially.

I am a creative person, who loves learning, and solving complex problems so the pace of evolution within technology and science, the shock of the new, the opportunities this presents has kept the fascination alive for me.

I have never tired of the challenges and changes, and have had such fun writing elegant code, investigating and fixing all kinds of stuff and solving really tough problems. Whilst I no longer ‘officially’ code (I have a raspberry pi at home) my role allows me to think and deliver tactically and strategically and to problem solve every day on a scale I never dreamt of when I started out in 1979.
