About

I've had a breadth of experience from tiny startups to Google, where I currently manage products with millions of users. I've honed my skills in eCommerce at Ocado, tackled fraud and authentication for online marketplaces at Ricardo.ch, and improving the buyer experience at tutti.ch. From this, I've got a deep understanding of the product development lifecycle, from ideation to launch and beyond. I'm adept at leveraging data and machine learning to inform product strategy and innovation, and I thrive on the challenge of creating products that make a difference. Whether it's optimising user experience, driving growth, or developing cutting-edge AI solutions, I'm always looking for new ways to create value for users and businesses alike. I recently even branched out into Entrepreneurship with the launch of my own anti-odourant company, http://athon.store.
