๐Ÿš€ About Me

I'm an e-commerce specialist with 5+ years of experience architecting and scaling Salesforce Commerce Cloud (SFCC/SFRA) platforms for global retail brands. My work covers PLP/PDP, cart, checkout, OCAPI/SCAPI and payment integrations, with measurable impact on conversion and cart performance.
