I’m an eCommerce Manager who lives and breathes online retail — managing everything from listings and marketing to warehouse coordination and 3PL operations. I currently run multi-channel sales across eBay, Amazon, Backmarket, and OnBuy for a UK refurbished tech brand doing over £1M a year.

I love finding smarter, data-driven ways to grow sales, simplify processes, and make online stores perform better. Outside of work, I’m building a few side brands in tech, collectibles, and fishing gear — because I’m always testing new ideas and chasing what’s next in eCommerce.
