Hi there! I'm Mario.

I combine hands-on experience of tech startups (a few of which I've founded or co-founded as CTO) and 25+ years of experience in the market research technology area with a keen interest in up-and-coming technology trends.

I like to keep up to date and learning, and am always experimenting with new technologies. Recently I have been particularly interested in and working with/developing for conversational interfaces, chatbots and voice assistants.
