Sean Pertet, Founder of Obsidian Web

Meet the founder, Sean Pertet

I'm a full-stack developer with a background in e-commerce and cloud engineering. After graduating from the University of Manchester, I joined an award-winning e-commerce agency in Manchester where I honed my skills building Shopify and BigCommerce stores alongside cloud integrations.

Over the years, I've worked with numerous merchants to improve store performance and deliver complete online experiences—from initial store configuration all the way through to launch. I've integrated with platforms like Bloomreach, Ometria, Klevu, SAP, and Caliq, and built beautiful storefronts that help businesses succeed.

Today, I work with clients to build fast, reliable websites and handle the technical infrastructure that keeps them running smoothly.
